• PhD Viva Voces – A Complete Guide
• Doing a PhD
• A PhD viva involves defending your thesis in an oral examination with at least two examiners.
• The aim of a PhD viva is to confirm that the work is your own , that you have a deep understanding of your project and, overall, that you are a competent researcher .
• There are no standard durations, but they usually range from one to three hours, with most lasting approximately two hours .
• There are six outcomes of a PhD viva: (1) pass without corrections (2) pass subject to minor corrections, (3) pass subject to major corrections, (4) downgrade to MPhil with no amendments, (5) downgrade to MPhil subject to amendments, (6) immediate fail.
• Almost all students who sit their viva pass it, with the most common outcome being ‘(2) – pass subject to minor corrections’.

What Is a PhD Viva?

A viva voce , more commonly referred to as ‘viva’, is an oral examination conducted at the end of your PhD and is essentially the final hurdle on the path to a doctorate. It is the period in which a student’s knowledge and work are evaluated by independent examiners.

In order to assess the student and their work around their research question, a viva sets out to determine:

• you understand the ideas and theories that you have put forward,
• you can answer questions about elements of your work that the examiners have questions about,
• you understand the broader research in your field and how your work contributes to this,
• you are aware of the limitations of your work and understand how it can be developed further,
• your work makes an original contribution, is your own and has not been plagiarised.

Note: A viva is a compulsory procedure for all PhD students, with the only exception being when a PhD is obtained through publication as opposed to the conventional route of study.

Who Will Attend a Viva?

In the UK, at least two examiners must take part in all vivas. Although you could have more than two examiners, most will not in an attempt to facilitate a smoother questioning process.

One of the two examiners will be internal, i.e. from your university, and the other will be external, i.e. from another university. Regardless, both will be knowledgeable in your research field and have read your thesis beforehand.

In addition to your two examiners, two other people may be present. The first is a chairperson. This is an individual who will be responsible for monitoring the interview and for ensuring proper conduct is followed at all times. The need for an external chairperson will vary between universities, as one of the examiners can also take on this role. The second is your supervisor, whose attendance is decided upon by you in agreement with your examiners. If your supervisor attends, they are prohibited from asking questions or from influencing the outcome of the viva.

To avoid any misunderstandings, we have summarised the above in a table:

Note: In some countries, such as in the United States, a viva is known as a ‘PhD defense’ and is performed publicly in front of a panel or board of examiners and an open audience. In these situations, the student presents their work in the form of a lecture and then faces questions from the examiners and audience which almost acts as a critical appraisal.

How Long Does a Viva Last?

Since all universities have different guidelines , and since all PhDs are unique, there are no standard durations. Typically, however, the duration ranges from one to three hours, with most lasting approximately two hours.

Your examiners will also influence the duration of your viva as some will favour a lengthy discussion, while others may not. Usually, your university will consult your examiners in advance and notify you of the likely duration closer to the day of your viva.

What Happens During a Viva?

Regardless of the subject area, all PhD vivas follow the same examination process format as below.

Introductions

You will introduce yourselves to each other, with the internal examiner normally introducing the external examiner. If an external chairperson is present, they too are introduced; otherwise, this role will be assumed by one of the examiners.

Procedure Explained

After the introductions, the appointed chair will explain the viva process. Although it should already be known to everyone, it will be repeated to ensure the viva remains on track during the forthcoming discussion.

Warm-Up Questions

The examiners will then begin the questioning process. This usually starts with a few simple opening questions, such as asking you to summarise your PhD thesis and what motivated you to carry out the research project.

In-Depth Questions

The viva questions will then naturally increase in difficulty as the examiners go further into the details of your thesis. These may include questions such as “What was the most critical decision you made when determining your research methodology ?”, “Do your findings agree with the current published work?” and “How do your findings impact existing theories or literature? ”. In addition to asking open-ended questions, they will also ask specific questions about the methodology, results and analysis on which your thesis is based.

Closing the Viva

Once the examiners are satisfied that they have thoroughly evaluated your knowledge and thesis, they will invite you to ask any questions you may have, and then bring the oral examination to a close.

What Happens After the Viva?

Once your viva has officially ended, your examiners will ask you to leave the room so that they can discuss your performance. Once a mutual agreement has been reached, which can take anywhere from 10 minutes to an hour, you will be invited back inside and informed of your outcome.

PhD Viva Outcomes

There are six possible outcomes to a viva:

• Immediate award of degree: A rare recommendation – congratulations, you are one of the few people who completely satisfied your examiners the first time around. You do not have to do anything further at this point.
• Minor amendments required: The most common recommendation – you obtain a pass on the condition that you make a number of minor amendments to your thesis, such as clarifying certain points and correcting grammatical errors. The time you have to make these changes depends on the number of them, but is usually one to six months.
• Major amendments required: A somewhat uncommon recommendation – you are requested to make major amendments to your thesis, ranging from further research to collecting more data or rewriting entire sections. Again, the time you have to complete this will depend on the number of changes required, but will usually be six months to one year. You will be awarded your degree once your amended thesis has been reviewed and accepted.
• Immediate award of MPhil: An uncommon recommendation – your examiners believe your thesis does not meet the standard for a doctoral degree but meets the standard for an MPhil (Master of Philosophy), a lower Master’s degree.
• Amendments required for MPhil: A rare recommendation – your examiners believe your thesis does not meet the standard for a doctoral degree, but with several amendments will meet the standard for an MPhil.
• Immediate fail: A very rare recommendation – you are given an immediate fail without the ability to resubmit and without entitlement to an MPhil.

Finding a PhD has never been this easy – search for a PhD by keyword, location or academic area of interest.

What Is the Pass Rate for Vivas?

Based on an  analysis of 26,076 PhD students  who took their viva exam between 2006 and 2017, the PhD viva pass rate in the UK is 96%; of those who passed, about 80% were required to make minor amendments to their thesis. The reason for this high pass rate is that supervisors will only put their students forward for a viva once they confidently believe they are ready for it. As a result, most candidates who sit a viva are already well-versed in their PhD topic before they even start preparing for the exam.

How Do I Arrange a Viva?

Your viva will be arranged either by the examiners or by the chairperson. The viva will be arranged at least one to two months after you have submitted your thesis and will arrange a viva date and venue that is suitable for all participants.

Can I Choose My Examiners?

At most universities, you and your supervisor will choose the internal and external examiners yourselves. This is because the examiners must have extensive knowledge of the thesis topic in order to be able to examine you and, as the author of the thesis in question, who else could better determine who they might be than you and your supervisor. The internal examiner is usually quite easy to find given they will be from your institution, but the external examiner may end up being your second or third preference depending on availability.

Can I Take Notes Into a Viva?

A viva is about testing your competence, not your memory. As such, you are allowed to take notes and other supporting material in with you. However, keep in mind that your examiners will not be overly impressed if you constantly have to refer to your notes to answer each question. Because of this, many students prefer to take an annotated copy of their thesis, with important points already highlighted and key chapters marked with post-it notes.

In addition to an annotated copy of a thesis, some students also take:

• a list of questions they would like to ask the examiners,
• notes that were created during their preparation,
• a list of minor corrections they have already identified from their viva prep work.

How Do I Prepare for a PhD Viva?

There are several ways to prepare for a PhD viva, one of the most effective being a mock viva voce examination . This allows you to familiarise yourself with the type of viva questions you will be asked and identify any weak areas you need to improve. They also give you the opportunity to practise without the pressure, giving you more time to think about your answers which will help to make sure that you know your thesis inside out. However, a mock viva exam is just one of many methods available to you – some of the other viva preparation methods can be found on our “ How to Prepare for a PhD Viva ” page.

November 30th, 2021, defending a phd thesis is an emotional moment candidates and supervisors should be prepared for.

4 comments | 55 shares

Estimated reading time: 6 minutes

The PhD defence, or viva, is significant academic rite of passage, which as well as marking the culmination of years of study, can also be a highly charged emotional moment.   Drawing on years of collecting accounts of PhD defences on her blog and her recent book (Planning and Passing Your PhD Defence, co-authored with Olga Degtyareva),  Eva Lantsoght , discusses how both PhD students and supervisors can benefit from a more engaged understanding of the emotions underlying the PhD defence. 

In the days leading up to my doctoral defence, I had a recurring nightmare about my supervisor forgetting to show up for my defence. I was well-prepared, and since I was defending in the Netherlands, my thesis was already printed and approved. Failing was virtually impossible. Why then, was I nervous about my doctoral defence to the point of having recurring nightmares?

After eventually passing my doctoral defence, I decided to collect stories about the doctoral defence (or viva, depending on the country) around the world for my blog. I was originally fascinated by the differences between defence formats (such as the sword newly minted doctors receive in Finland and the medal in Chile ). Over time, however, I started to see that below the superficial differences, all types of defence show similarities. One is that there is always an emotional dimension to the defence. My worries before my defence were hardly an isolated case. Many doctoral candidates report strong emotions around thesis submission, in the weeks leading up to the defence, during the event, and even afterwards, when the post-defence blues may kick in.

Typically, discussions on the doctoral defence centre around the scholarly dimension. A defence is often viewed solely as an academic event marking and evaluating the end of a research project

Typically, discussions on the doctoral defence centre around the scholarly dimension. A defence is often viewed solely as an academic event marking and evaluating the end of a research project. However, in our recent book Planning and Passing Your PhD Defence , which I co-wrote with Olga Degtyareva, we have paid special attention to the emotional dimension of the defence (of course, in addition to the scholarly dimension preparing for answering questions, and other traditional aspects related to the doctoral defence). This was in part because, we strongly felt that we shouldn’t consider the defence as a regular examination, where a standard set of criteria are used to assess a student. Besides its function as an examination, the defence is also a rite of passage, a confirmation, a celebration, and the culmination of years of independent research work. Emotions are murky and difficult to factor in for assessment. The emotions involved in the doctoral defence make it a unique event: for the candidate, the examiners (or committee members), and for the supervisor. Being aware of these emotions, and bringing them to light, is important to understanding the defence better and the role it plays in a research career.

In my work on the doctoral defence, I found (to my surprise) that the major differences between defence formats did not influence the candidates’ perception much . On the other hand, I did find important differences in the emotions felt by candidates related to the defence, as a function of socio-demographic aspects, notably gender. Women doctoral candidates experience more negative feelings before the defence, and if they had a negative experience during the defence, the negative impact on their perception as a researcher could often be long-lasting. Being aware of how different groups experience the emotions related to the defence differently is important, especially for supervisors and examiners, and can be empowering for candidates. Besides simply being aware of the emotional dimension, it can also enable the small changes that can help settle things when emotions run high: taking a short break, offering water, getting up to open a window, or moving to another topic of the thesis.

While each PhD candidate, each research study, and each PhD trajectory are unique, there are some common emotions that deserve to be mentioned. First of all, in the weeks or days leading up to thesis submission, candidates often feel that the work is not enough, worthless, or otherwise insufficient, and these feelings can contribute to perfectionism. Other candidates may be so tired of the thesis that every small action may feel like a terrible chore. Some feel relieved upon submission, and others worry about how it will be received.

Many candidates also worry about how they will perform. For candidates in the United Kingdom, where the viva takes place before final submission of the thesis and may determine the level of corrections required for the thesis, candidates worry about what the outcome of the thesis and viva will be. Major revisions could potentially add months to the doctoral journey. Because the viva is behind closed doors, candidates also may not know very well what to expect. In the Netherlands, where candidates are sure they will pass, other causes lead to worry and anxiety. As the defence is public, candidates feel the pressure to perform well in front of the committee, friends, colleagues, and family.

it is also important for supervisors and examiners to be aware of this emotional dimension, and to know how different groups of candidates experience these emotions

The first step in dealing with this anxiety, is to name and acknowledge it, and to know that these feelings are normal. Candidates who passed without corrections worry about passing their defence as much as those who had more work on their thesis after the defence. Breathing techniques, meditation, and relaxation exercises can help. University counselling services should be there to support as well. Being well-prepared for the day of the defence itself may also help candidates to feel more in control over the day and their feelings. A positive action, such as stopping by colleagues and expressing gratitude to them before the defence, can improve defence-day-anxiety. Many candidates feel more nervous right before and at the beginning of their defence. Taking notes, repeating the question, or asking for clarification of the question, are all valid options to start answering in a calm and controlled manner. At the end of the defence, candidates can be nervous to hear the outcome, and the minutes while the committee is in deliberation may feel like hours. Then, after hearing the verdict, often the final flood of emotions (relief, happiness, pride, or perhaps disappointment, anger, or worry about the thesis revision) comes.

Emotions play an important role leading up to and during the doctoral defence. Understanding the role of these emotions is important for candidates, so that they know that what they are feeling is normal, and does not mean that they are not worthy of a doctorate. At the same time, it is also important for supervisors and examiners to be aware of this emotional dimension, and to know how different groups of candidates experience these emotions. Being aware of and holding space for these emotions allows all those who are involved in the defence to experience the defence, not simply as a test of knowledge, but as the important moment it is, in the formation and affirmation of a new scholar.

Defending your PhD thesis in… the United Kingdom

Verena Brähler , one of our Researching Security Fellows, is sharing with us her experience of defending her PhD thesis in the United Kingdom.

September 2014

Thesis defence procedure in the United Kingdom

Contrary to most other countries in Europe, the PhD thesis defence in the United Kingdom is not a formality. The thesis defence in the UK is called viva voce (“with the living voice”). It is an oral examination with two examiners and may require a substantial amount of preparation. Usually you will have one internal examiner from your university and one external examiner. Unless you request otherwise, your supervisor(s) will not be present during the examination and neither will be any members of the public. That is quite nice actually because the examiners will focus on discussing the most important aspects of your thesis, rather than asking tough questions “to entertain the audience”. The examination can take between two and four hours and these are the most common outcomes:

• Pass: I personally do not know anyone who has passed the viva straight away but, theoretically speaking, it is possible.
• Pass with minor corrections: This is the most common outcome. You get 3 months to make minor amendments to your thesis, based on what was discussed during the viva.
• Major corrections: This seems to happen to very few people. It means that you get another 18 months to make substantial changes to your thesis.
• Fail: Theoretically speaking, there is a possibility that you can fail but I have never heard of anyone who did.

Preparation

Given these different outcomes, it is smart to prepare for the viva. In my case, I submitted my thesis in March 2014 and had six weeks to prepare for the viva in the beginning of May. At the time, I was already working in Vienna and doing an internship with UNODC. I used the two weekends prior to my viva to read the whole thesis again (you wouldn’t believe how many typos I still found) and think about how I would answer the following questions:

• What is original about your thesis? What sets your work apart from others?
• What are the strongest/weakest parts of your work?
• What were the crucial research decisions that you made? How did you resolve any issues which arose in the course of your research?
• How did you tackle the ethical implications of your work?
• Who is your audience?
• What is the agreed methodology in your discipline?
• Do you anticipate publishing the material? And, if so, what aspects?
• What researchers would be interested in your work?
• What are the theoretical underpinnings to your work?
• Who would be most likely to agree/disagree with your findings?
• How long do you expect your work to remain innovative? Do your contributions have a limited timescale?
• Do you think that your recommendations are feasible?

One the day

My examination was in London. On the day, I felt pretty calm and well prepared. I always thought that I am a bit better in speaking than in writing, so I felt confident but not exactly über-enthusiastic. When I walked into the room, my two examiners welcomed me and started the viva by asking two ice-breaker questions:

• How did you come to research this topic?
• Do you have any plans to publish some of the materials?

Then in the following 40 minutes, the examiners went straight into criticising my main argument (“oligopoly of security providers in Rio de Janeiro”) and it was quite challenging to defend my research choices. The rest of the viva continued in a similar format. One of the professors would give a “mini-lecture” on a certain aspect of my thesis and I then had the opportunity to defend myself and explain my arguments. The whole process was quite exhausting but I also enjoyed it because it showed that these two very distinguished and well-known professors had read and analysed my whole thesis (a good 290 pages) in a lot of depth.

After the examination, I had to leave the room quickly so that the professors could decide on the outcome of the viva. When I was asked back into the room, they told me that I had passed with minor corrections and explained the changes I needed to make over the next three months. I was very happy with this result and felt relieved. We called my supervisor and together we had a glass of champagne and then went for dinner.

After defending the thesis

On the next morning, I had to go immediately back to Vienna to continue with my work at UNODC. The next day at work I felt that I must be one of the smartest and dumbest interns my department ever had. Smart because I had just passed my PhD viva and dumb because here I was, 28 years old and doing an unpaid internship. Two weeks later, I received the official report by the examiners. It was quite a lot of pages so I panicked a bit and then not looked at it again for the next two months while finishing the internship.

Upon my return to London, I immediately started working on the corrections and it took me a good three weeks. I must say it was quite difficult because after a few months of working outside academia, it felt like a huge step backwards to work on the thesis again. I also felt under a lot of pressure to find a job and sometimes I felt that the thesis corrections were getting in the way of my job applications (or the other way around?). All in all, I must admit though that the thesis has been hugely improved by doing the minor corrections and I am grateful that I was forced to go through this rite of passage.

Useful information

For those preparing for the viva, I would recommend to watch these videos by Imperial College London which explain the examination process quite nicely. And if I can just give you one piece of advice: write your thesis as best as possible before you submit it! Little inconsistencies in your arguments, a weak theoretical framework or unfeasible policy recommendations may backfire at you during the viva. From my own experience, I can say that making changes to the thesis after the examination is a lot harder than before, simply because your mind will already be in another world.

Picture this: after countless hours of research, writing, and refining, you’re now standing on stage with your cohort, in a gown and funny hat, because … you’ve finally completed that last important milestone in your academic journey – defending your doctoral dissertation. It’s a culmination of years of dedication, determination, and sleepless nights.     You’re not there yet—but you’re close. So how do you make it past this final, nerve-wracking hurdle?  

In this article, we’ll deep-dive into the dissertation defense process, with tips, strategies, and straight-up information. I’ll share my expertise as a coach whose job it is to get people up on that stage.  

What to expect during the dissertation defense

A dissertation defense typically consists of an oral presentation to your dissertation committee, who have already received and read the final draft of your dissertation manuscript. Other members of your cohort and institution, and outside readers or experts, might also be present in the audience.  

Without fail, I see two different reactions to this news from my coaching students: either they are terrified of having their work scrutinized by their committee in public, or they are extremely laid back, knowing that they’ve already done all the hard work in the manuscript. (These later students are the ones paying attention to me).  

You probably already know the general gist of what happens in a defense presentation: you present the highlights of your study, the committee ask questions, and then they vote on whether you pass or need to complete further revision. So, here are some things you might not yet know:

• The oral defense gives the committee the opportunity to ask you about any areas of your study that are still unclear or weak on paper – so that you can prove they are not unclear or weak in real life. In other words, it’s a chance to get anything that got stuck in your head (rather than making it on to paper) out and in front of your committee.

• Your chair or supervisor and committee should not be allowing you to complete the defense process unless they are already confident that the biggest issues with your work have already been resolved.

• Questions are normal – your committee are working with you because your work interests them (hopefully), so questions are as likely to indicate their excitement about your work as a problem they have spotted.

• Revisions are normal – from requests to polish the grammar to insisting you add more supporting sources or develop your recommendations more thoroughly, “pass with revisions” is a normal, common, and expected end result. To pass with no revisions is pretty rare (although I have had a few students achieve this – looking at you, YY!) – like getting 100% on a calculus test in school.

In short, your defense presentation is nothing to be scared of. You are lined up for defense because both you and your committee feel you know your stuff, and now all you need to do is share what you’ve produced and learned and engage people in discussion about it. You got this!

Preparing for Your Dissertation Defense

Still nervous? Ok, that’s fair enough. As with many things, good preparation can help you get those nerves under control, so here are some top tips to help you get ready.

Tick the Boxes

It’s essential to understand the requirements and expectations of your defense committee. Get familiar with the specific guidelines and procedures set by your institution, and make sure you meet all necessary criteria. If you’re giving them what they ask for, you are definitely off to a strong start.

Know Your Stuff

This defense is about you showing off what you know, so before you stand up in front of the crown, take a deep dive into your own research masterpiece. Thoroughly review your dissertation, scrutinizing each chapter, section, and argument. Make notes. Look for anything that might provoke questions or debate. Remember, this is your opportunity to showcase your expertise and demonstrate the depth of your knowledge.

Seek Wise Counsel

Your advisor and committee members are the best resources you could ask for about defense. They set the guidelines, and they judge whether you have done well. Reach out to them for guidance, feedback, and advice—their collective wisdom and support can be instrumental in honing your presentation. And, if they are not all that … well, remember there are others out there who can help, including coaches, mentors, and past students.

Just like any performance, practice makes perfect. Take the time to rehearse your presentation multiple times, refining your delivery and strengthening your command over the content. By doing so, you’ll build confidence and ensure a smoother delivery when the day arrives. Even more importantly, you’ll settle the key points of your study firmly in your brain, making sure you sound like the expert you are.

Anticipate the Unknown

Obviously, you can’t predict every question or comment that will come up during your defense. However, you can still prepare yourself for potential challenges. Get cozy with the research landscape in your field and the interests of your committee members. Step outside of your own perspective and view your work through a stranger’s eyes to anticipate areas of critique or alternative viewpoints. This will enable you to respond thoughtfully and demonstrate your ability to engage in scholarly discourse.

Managing Nerves and Anxiety

You know what’s coming and you know how to prepare – are you still nervous? If so, know that that is completely normal. Here’s how me and two of my students got their dissertation defense nerves under control.

An Awesome Supervisor

For my own dissertation defense (known as a viva voce in the UK), I was incredibly lucky to have a supervisor with whom I had a strong, supportive, and nurturing relationship. Although the main examination of my work was handled by the external reader, who sat across from me behind a big desk, my supervisor sat behind him and nodded and smiled encouragingly every time I said something. Words can’t describe how much that calmed me down and gave me confidence. If you are as lucky as me and have an awesome supervisor, tell your nerves they can stand down – your supervisor’s got your back!

You Can Get Used to Anything

One of my students, who graduated last year, suffered from terrible defense nerves because she was worried about holding so much complex information in her head and delivering it coherently. Her solution? She practiced endlessly, over the course of about a month.

With me as her coach playing the role of audience, or with her kids and other family members, her cohort peers, her dog, and even other academics, she presented that study until she could do so in her sleep. The point was that, by the time the actual defense day rolled around, presenting the study to people was comfortable, familiar territory. Done and dusted!

Temporary Denial

Another student, who graduated shortly after, took completely the opposite approach to managing dissertation defense nerves. This student was burnt out from a huge rush to meet an unexpectedly tight deadline for the final manuscript when her chair decided to retire at the last minute. Rather than burn herself out further, she hit send on the manuscript, paid a designer to polish the design of the presentation rough draft, and then shut down her devices and went on holiday with her family. For one week, she did not look at or talk about her research at all. Instead, she sat on the beach, ate ice cream, and scrolled Instagram (probably). Then, she returned to work (a week before the presentation), refreshed and feeling excited about her work again. The break enabled her to practice and prepare in a calm frame of mind.

Some Parting Thoughts

I won’t walk you through the other obvious stuff, like what makes a good presentation PowerPoint or how body language and appearance can improve your presentation skills—that stuff is what Google is for. You’re an expert by now at finding the information you need, so get out there and find it. However, know that if you need help getting ready for your defense, there are definitely humans around you (and some dogs) who want to help – whether that’s your chair, your family, or a coach like me. I recommend you find them now and let them tell you just how ready for this you are.

To Be or Not To Be (a Reviewer 2): Should I Review Articles as a PhD Student?

For the wheels to continue turning in research, we need reviewers. Although often a thankless endeavour (littered with Reviewer 2 jokes), acting as a gatekeeper for the integrity of your research field remains vital. As a PhD student, you may find the process of reviewing a manuscript pretty novel, but a reviewer request email may enter your inbox in the near future. This article guides you through the pros and cons of reviewing articles.

‘Stairway to Lecture’: A Roadmap to Progress from PhD to Lecturer

Once you have submitted your dissertation, you may be asked to do a defence of your dissertation. This could be in the form of an oral presentation, a poster presentation of your findings, or you could be invited to a viva voce. Vivas, as they are usually known, are particularly common for research degrees such as MPhils or PhDs and are essentially a verbal defence of your thesis that is conducted in an interview style format. At a minimum, the viva is a way of checking you authored the thesis yourself and understand the detail, but it is also an opportunity to discuss your research findings and interpretations in depth with experts. Preparation is key for defending your thesis in a viva or a presentation format. With a bit of groundwork, you could even enjoy the discussion, after all the thesis is the culmination of all your hard work, and no one knows it better than you.

How to Defend a Thesis: An Introduction to the PhD Viva

The prospect of defending your PhD work can be more than a little daunting. It represents the climax of many years of hard work, you’ll have to defend a thesis in front of experts in your field and the whole PhD viva process can seem cloaked in mystery.

Maybe you’ve seen a labmate go for their PhD viva to then emerge several hours later, relieved but perhaps slightly dazed. Often it’ll be the case that they’ll have forgotten the specifics by the time they’ve left the room. On top of that, horror stories of bad PhD viva experiences pass through many research groups which are enough to make even the most confident and positive PhD students shake in their boots.

Having had my own PhD viva earlier this year, in addition to discussing experiences with many other PhD graduates, I now want to help you through the process.

Before we begin, I want to offer some reassurance. For most people the PhD viva is not at all the horrible experience we occasionally hear about. Even so, it’s still useful to know what to expect. I’ve therefore put together a series to help others understand the PhD viva process and how to defend a thesis.

Defend a Thesis: Overview of the PhD Viva Series

This first post will be an introduction to the PhD viva process and how to defend a thesis. Upcoming posts will cover:

• Viva Preparation: Common PhD Viva Questions
• What is a PhD Viva Like? Sharing Graduates’ Experiences
• How to Choose Your Examiners

If there is anything specific you’d like covered, please let me know! I’ll be sure to include it. If you’d like to subscribe to get notified of upcoming posts as they’re released you can do so here:

How is a PhD Assessed?

Typically the main output expected at the end of your PhD project is a thesis. You’ve put years of work into your PhD and the thesis details your contributions to your chosen research field. But how is the thesis “marked”? Who will decide if what you’ve written is actually any good?

This is where the PhD viva comes in!

The PhD viva involves you discussing and defending your work with experts in your field. The experts act as examiners to determine whether or not the university should award you a PhD based on your thesis and viva performance. The thesis is the written report submitted for a PhD, and the viva is a means of quality control to ensure that only suitable candidates are awarded a PhD by the university.

Although part of the purpose of a PhD viva is to ensure that the work is of a high quality, just as importantly it’s to check that you were the one who carried it out and that you understand what you were doing!

The PhD viva is therefore essentially an exam during which you’ll have to defend a thesis.

Here is the official “mark scheme” for a PhD at Imperial:

I recommend looking at the presentation which this screenshot came from: sadly I only came across it after my own PhD viva whilst putting together this post!

Steps to Completing a PhD

• Submit your thesis for the examiners to read ahead of the viva.
• Have the viva , where you’ll defend a thesis and discuss your research. The examiners will decide from a list of possible outcomes as detailed later in this post.
• Make amendments to the thesis as necessary.
• Optional celebration.
• Have the thesis amendments approved by the examiners and/or your supervisor and confirmation sent to the university.
• Upload the final copy of your thesis to the university.
• Eagerly await notification that you’ve been awarded a PhD by the university!
• Celebrate, Dr!

All celebrations except for the one after making changes to your thesis are mandatory!

PhD Viva vs PhD Defence

The words viva and defence are sometimes used interchangeably, but often are used to reference the different ways that the a PhD is concluded around the world.

A PhD viva (technically a viva voce ) is a formal examination of a PhD. It’s typical in the UK (amongst other countries) and it is a closed-event between yourself and some examiners.

Across much of Europe it is common instead to have a PhD defence . This still involves expert questioning but can be more of a ceremony and may even be open to the public. You can read about Siddartha’s experience , who completed his PhD in the Netherlands.

I went through a PhD viva and that’ll be the focus of this series. Nevertheless, there is overlap and you may still have difficult questions in a PhD defence, so the content in this series should still be useful no matter where you’re based.

In both a PhD viva and a PhD defence you’ll be expected to defend a thesis which represents the culmination of your work during the PhD.

Who is Present During the PhD Viva?

In the UK it is typical for the PhD viva to include:

• One or more experts from your university ( internal examiner ).
• One or more experts in your field from another institution to your own ( external examiner ).
• And sometimes your supervisor, though in my experience this is quite rare unless you actively ask them to be there.

The main role of the internal examiner is to act as a moderator and ensure that the university’s protocols are upheld. They’ll usually still have some questions for you, but on top of that they’ll make sure that the external examiner(s) are reasonable. They will also take charge of documenting the viva.

Often the external examiner will be more specialised to your field than the internal examiner, so expect them to potentially ask more tricky and technical questions.

As mentioned in the previous section, for PhD defences in other countries the event may be less of an exam (viva) and more of a celebration of your work. These can be a lot more open, with access granted to your friends, family or anyone else who is interested in the topic. I quite like this idea, especially when the research has been publicly funded!

How the PhD Viva is Structured

The structure of the viva will vary but a typical format is shown below. The times in brackets are how long the sections for my own viva were, thankfully not all vivas are over five hours long!

• Introductions (2 minutes) – greeting the examiners and they’ll usually quickly give an overview for how they want the viva to go.
• Presentation (10 minutes) – Not all examiners will want you to give a presentation, it’s best to ask them in advance. I believe many examiners like asking for presentations: both to ease into the exam and also to see how you do at distilling years of work into a short presentation.
• Discussion (Over 5 hours, yes, really!) – the long and potentially scary bit.
• A short break (~10 minutes) . You’ll leave the room (or video call!) and the examiners will come to a decision for your PhD outcome.
• Decision and final comments (10 minutes) – where the examiners will tell you what the outcome is of the viva – we’ll cover this in more depth in the next section.

The discussion in the middle of course is the main guts of the PhD viva, and the potentially scary bit. This is where you’ll get questioned about your work and thesis. What you get asked could vary considerably depending on your thesis and examiners.

I’ll save an in-depth discussion of my own viva for another post. In short, I received very few questions relating to the work or any fundamental underlying science. There were practically no questions to quiz my knowledge.

Rather than checking my understanding of the work, the viva was much more of a discussion of how best to present the work in the thesis. We spent roughly an hour going page by page through each chapter. This included suggestions for improvements to figures, changes in terminology and the like.

Possible PhD Viva Outcomes

At the end of the viva the examiners will give you feedback. This will include feedback on your performance in the viva. But as long as they’re satisfied that you carried out the work and that you knew what you’re doing, the bulk of the feedback will in fact revolve around your PhD thesis.

Technically there are lots of potential outcomes, as detailed here:

In reality here are the four main possible outcomes from the viva:

• Pass with no amendments . The examiners didn’t want to make a single alteration to your thesis. Well done you just have to submit the finalised thesis to the university and you’ve finished your PhD! I know a few people who’ve had no revisions but it’s rare.
• Pass with minor amendments Minor amendments include things such as correcting typos, rewording sentences and small alterations to data analysis and presentation. This is by far the most common outcome.
• Referral for resubmission ( major amendments). More substantial changes to the thesis are required or further experimental work is required to fulfil the requirements of a PhD. The examiners will decide whether or not this means having another viva too.
• Fail . Unless there are glaring issues or you didn’t actually do any of the research in your thesis yourself, you should be relieved to hear that practically no one ever fails. If you have failed, it usually points to systematic issues revolving around your supervisor: you shouldn’t have been allowed to get to this point. Usually the examiners would recommend that you be awarded a lower degree, such as a masters in research (MRes).

Slightly up the page is a screenshot from my own examiners’ report. You’ll see that I, like most people, passed with minor amendments.

Making Changes to Your PhD Thesis

Shortly after the viva you should receive the examiner’s report which includes a list of revisions for you to make.

If you’ve got through the viva with a pass, you can breathe a sigh of relief because the hard work is over! In a separate post I’ll be covering how the process to make my own minor amendments went.

No matter the outcome, it is possible that you’d like to make your own changes to the thesis since it’ll have been many weeks (or months) since submitting the draft copy for your viva. On reflection there may be things you’re not happy with. You are welcome to make changes to the document yourself.

If you’re interested in reading more about how to make the corrections to your thesis, read the article dedicated to it here: Minor Corrections: How To Make Them and Succeed With Your PhD Thesis.

After you’ve made changes, the final stage in getting awarded the PhD is submitting your finalised version of the thesis to the university. Shortly afterwards you’ll get the long-awaited notification that you’ve got your PhD!

Should You Strive For No Amendments?

In my opinion it’s not worth the effort of trying to get no amendments.

I’d personally rather spend slightly less time up front, knowing that more than likely I would have to made some amendments. You can never put in enough work to ensure there will be nothing your examiners want changed!

You could spent hundreds of extra hours endlessly going through your thesis meticulously before submission but your examiners can always find something they want you to change. In comparison, my own minor amendments only took two days of work.

Sometimes you’ll see someone mention on their CV that they passed with no revisions but it doesn’t really have any bearing on your PhD. Unlike most other qualifications, there aren’t really grades for PhDs: you either have one or you don’t.

During an early PhD assessment my assessor made a poignant joke about medical degrees: “What do you call the person who graduates bottom of their class in medical school? A doctor!” And it’s essentially the same with PhDs!

How to prepare for your PhD thesis defence

• by James Hayton, PhD

The 3 habits that saved my phd, how to design figures for your phd thesis.

What’s the best way to prepare for your PhD thesis defence? The tips below will help you in the final few weeks before the exam, but the real preparation begins as soon as you start your PhD . Talking to people and discussing your work regularly over a long period of time is the best preparation, so don’t let your thesis defence be the first time you get feedback on your work!

Know the format of your PhD thesis defence

The format of a PhD thesis defence varies from country to country. Having studied in the UK, my viva-voce defence was essentially an interview with one internal and one external examiner. In other countries, it’s common to have public examinations with a whole panel of examiners and an audience of colleagues, family and friends. The first and most obvious tip, then, is to make sure you know what the format of your exam will be; whether you will have to prepare a presentation and so on.

Prepare and practice your presentation

If you have to give a presentation, check any time restrictions so you can prepare accordingly. You don’t want to show up with 100 slides for a 15-minute presentation, nor do you want to show up with 3 slides for a 1-hour presentation.

The most important thing to do for any presentation is to practice so that;

• You know the material inside out
• You know how long it takes
• You can refine the presentation

You can practice on your own or with an audience, and you should do both if possible. Practicing on your own and speaking out loud to an empty room may feel silly, but overcoming that discomfort is good preparation for the discomfort of facing an actual audience. Practicing with an audience of peers is then a good way of getting feedback and finding out what questions people ask.

The dreaded “awkward question”

A common fear is being asked a question you can’t answer. It’s tempting to try to read a ton of literature to prepare for this, but since it’s very difficult to predict what the examiners will ask and it’s impossible to read everything, this approach isn’t always effective or reassuring (it might just make you realise how much you don’t know).

You aren’t expected to know everything. Sometimes, an examiner will ask a question they don’t know the answer to, either out of interest (since you are the expert in your research) or because they want to see how you think. While it is OK, sometimes, to just say “I don’t know”, you could also say something like,

‍ “I don’t know, but I would think that […] because of x and y , but you would need to do […] in order to find out” .

This shows that you have the ability to think as an academic.

Core content

Of course, there is some core content which you will be expected to know well, but this is set by you, not the examiner. To a large extent, the content of the examination is determined by the content in your thesis.

When you choose what to cover in your thesis you are choosing your battleground for the thesis defence. The best strategy, then, is to stick to the material you know best in your writing!

Dealing with nerves in your thesis defence

You will be nervous before your examination. You will almost certainly get an adrenaline rush, which can set your heart racing, give you sweaty palms, make your stomach churn and make you want to go to the toilet 10 times in 20 minutes. This is normal!

The worst part is waiting to start because there isn’t much you can do to use up your nervous energy. But once the defence starts, you can do some things to keep it under control.

One symptom of nerves is to talk really fast and to try to show how much you know and speak in this kind of long stream of consciousness that diverges away from the question until you forget what the actual question was but then you don’t know how to get back to the point and so you just keep talking and that makes you more nervous and how are you going to get off this train of thought…

Try to slow down and give yourself time to breathe. Try to remember the question* and come back to the point. Once you have answered, stop talking!

*If you forget the question, it’s OK to say, “sorry, I got lost in my train of though there, what was the question, again?”

The examiners expect you to be nervous

Remember that the examiners expect you to be nervous, and they will help you through if necessary. It’s OK to ask them to repeat or clarify a question, to pause to think, or to take a sip of water if you need to!

Ultimately…

Success or failure is determined mainly by the content of your thesis. If your research is good, and you actually did the work, it’s unlikely that a nervous performance in your defence will lead to failure. Generally speaking, once your thesis is submitted, there isn’t much you can do to affect the outcome (positively or negatively). Read through your thesis, read up on one or two key points if necessary, practice your presentation, and trust that whatever happens you will be OK.

Viva, Soutenance, Disputation: How PhD Students around the World Defend Their Thesis | Lex Academic Blog

22 November 2021

Our recent posts on avoiding major and minor PhD corrections focused primarily on the run-up to and aftermath of defending a thesis in the UK. It occurred to us that for students considering a PhD, or established UK-based academics who have been asked to examine a PhD abroad, it would be useful to know how students in different countries defend their thesis. For the sake of readers unfamiliar with the UK system, let’s begin with a summary. In the UK, students defend their thesis in front of two examiners, at least one of whom must be external to the student’s university, in an examination called a viva voce , or viva. After the exam, the examiners make one of four recommendations: pass with no corrections, pass with minor corrections, pass with major corrections, or fail – resubmission. The majority of students pass with corrections (for more on the difference between minor and major corrections, click the links above), which the student must implement before they can be awarded their degree.

Like those in the UK, students in the US and Australia are usually required to make amendments to their thesis after examination. PhD programmes in the US require students to take and pass oral examinations, or ‘defences’, at regular intervals. Unlike in the UK, where students rarely know their examiners well, as this testimony shows, students in the US system are examined by the same committee throughout their studies. In Australia, the process of submitting and defending a thesis seems to vary between institutions. At the University of Sydney , for instance, students, in consultation with their supervisor, choose between a viva-like oral examination and a thesis-only examination, where the examiners each produce an extensive review of the thesis. The University of Melbourne requires students to present their research at a public completion seminar in the six months before submission.

In many European countries, the concept of PhD corrections doesn’t exist. At the Freie Universität Berlin in Germany, students are awarded a grade ( summa cum laude (distinction), magna cum laude (very good), etc.) for their doctorate, based on the thesis itself and their performance at their viva, or Disputation . Once the thesis has been corrected by the examiners, it is made available for viewing by postdoctoral members of the student’s department before the Disputation . Students in Germany must also publish their thesis in order to receive their award. Unlike a viva in the UK, a French soutenance is a public event. Students defend their thesis in front of a jury , or panel, of examiners. The supervisor, who in the UK may attend a viva but is prohibited from speaking, is usually a member of the panel. The student first gives a presentation about their thesis topic and then responds to questions from each examiner. Unlike in the UK, students in the French system don’t make corrections to the thesis after defending. Instead, the examiners produce a report on the strengths and weaknesses of the thesis, which is a key part of academic job applications, even for senior positions.

In Scandinavian countries, the defence of a PhD thesis is often a ceremonial, highly coded event (this piece by an American academic who was the external examiner for a thesis at a Swedish university describes how the student had to nail – literally – their abstract to a plank in a department common room as a symbol of the public release of the thesis!). At Halmstad University in Sweden, the student defends their thesis publicly and in the presence of an external specialist known as the ‘opponent’. The student may present their thesis, but it’s also possible for the opponent to present the thesis and compare it to existing research in the field. A similar system is used at the University of Helsinki in Finland, where traditionally a strict formal dress code must be adhered to. These codes may sound rather daunting, but in practice few students fail their defence (and the rules on dress are now the subject of debate). The public event is usually cancelled if an examiner deems the work to be below doctoral standard.

Because the process of submitting and defending a thesis varies considerably between countries, students thinking about a PhD, as well as those advising them, would be wise to make this process, as well as other factors like funding and duration, a part of their decision making when applying to universities. Even if you don’t really mind how your thesis is examined, it’s good to know what you’re letting yourself in for.

How to Prepare for Your Dissertation Defense

4-minute read

• 1st August 2023

After years of research and study, you’ve finally reached the grand finale of your PhD years: your dissertation defense. Since defending your dissertation is the culmination of all your hard work, it’s essential to do everything you can to prepare for it.

In this post, we’ll take you through how to ready yourself for your dissertation defense so you can focus on your accomplishments and excel during this crucial professional moment.

What is a Dissertation Defense? 

The dissertation defense is the crowning moment of years of research – the final examination before a PhD student is awarded their doctoral degree.

During a dissertation defense, the student presents their research, methodology, findings, and conclusions to a committee of faculty members and experts in their field. The committee then engages in a question-and-answer session to assess the student’s understanding of the subject matter, the quality of their research, and their ability to defend their work under scrutiny.

Many PhD students consider it to be the defining moment of their academic career and their chance to prove their expertise in their chosen research field.

If all this sounds overwhelming – don’t worry. If you’re a PhD student, you’ll have plenty of time and opportunity to adequately prepare for your dissertation defense. Below are some strategies to help you get ready for this significant occasion in your career.

1.   Know the Requirements

Familiarize yourself with your institution’s guidelines and requirements for the defense process. Understanding the format, time limit, and expectations for the presentation will help you to prepare your material and anticipate any issues.

2.   Review Your Dissertation

Even if you think you know it inside and out, review your dissertation from beginning to end. It may have been some time since you’ve last read and considered certain portions of your research and findings. Consider what your committee might ask about your research questions , data analysis, and conclusions.

3.   Work on Starting Strong

To begin your defense on a strong note, work on creating a clear and engaging introduction. You can start by briefly outlining the purpose of your study, research questions, and methodology . Try to stay on topic and don’t veer off track by discussing unrelated or unnecessary information.

4.   Practice Presenting

Practice your presentation skills by rehearsing your defense multiple times. Focus on clarity and pacing and try to stay within the allotted time limit. It also helps to record yourself so that you can see yourself from your audience’s point of view.

5.   Practice Q&A Sessions

To build your confidence, enlist friends and colleagues to conduct mock question-and-answer sessions. When practicing, remember to pause before answering questions you’re unsure of. It’s better to take your time delivering a response than it is to give an inaccurate or incorrect answer.

6.   Seek Feedback

Find out if your institution offers mock defense sessions where peers or mentors play the role of the committee, ask you questions, and give feedback . You can also have colleagues, mentors, or advisors review your presentation and offer practical feedback.

7.   Create Visual Aids

Think about any visual aids , such as slides, you may want to use to illustrate your defense and prepare them in advance. Be sure to check that your university allows visuals or images and that they enhance, rather than overwhelm, your presentation.

8.   Stay Calm and Confident

It’s natural to feel nervous but try to stay calm and composed during your defense. Take deep breaths and remind yourself of the expertise you’ve gained through the experience of writing your dissertation.

How to prepare an excellent thesis defense

What is a thesis defense?

If you're about to complete, or have ever completed a graduate degree, you have most likely come across the term "thesis defense." In many countries, to finish a graduate degree, you have to write a thesis .

A thesis is a large paper, or multi-chapter work, based on a topic relating to your field of study.

Once you hand in your thesis, you will be assigned a date to defend your work. Your thesis defense meeting usually consists of you and a committee of two or more professors working in your program. It may also include other people, like professionals from other colleges or those who are working in your field.

During your thesis defense, you will be asked questions about your work. The main purpose of your thesis defense is for the committee to make sure that you actually understand your field and focus area.

The questions are usually open-ended and require the student to think critically about their work. By the time of your thesis defense, your paper has already been evaluated. The questions asked are not designed so that you actually have to aggressively "defend" your work; often, your thesis defense is more of a formality required so that you can get your degree.

• Check with your department about requirements and timing.
• Re-read your thesis.
• Anticipate questions and prepare for them.
• Create a back-up plan to deal with technology hiccups.
• Plan de-stressing activities both before, and after, your defense.

How long your oral thesis defense is depends largely on the institution and requirements of your degree. It is best to consult your department or institution about this. In general, a thesis defense may take only 20 minutes, but it may also take two hours or more. The length also depends on how much time is allocated to the presentation and questioning part.

Tip: Check with your department or institution as soon as possible to determine the approved length for a thesis defense.

First of all, be aware that a thesis defense varies from country to country. This is just a general overview, but a thesis defense can take many different formats. Some are closed, others are public defenses. Some take place with two committee members, some with more examiners.

The same goes for the length of your thesis defense, as mentioned above. The most important first step for you is to clarify with your department what the structure of your thesis defense will look like. In general, your thesis defense will include:

• your presentation of around 20-30 minutes
• questions from the committee
• questions from the audience (if the defense is public and the department allows it)

You might have to give a presentation, often with Powerpoint, Google slides, or Keynote slides. Make sure to prepare an appropriate amount of slides. A general rule is to use about 10 slides for a 20-minute presentation.

But that also depends on your specific topic and the way you present. The good news is that there will be plenty of time ahead of your thesis defense to prepare your slides and practice your presentation alone and in front of friends or family.

Tip: Practice delivering your thesis presentation in front of family, friends, or colleagues.

You can prepare your slides by using information from your thesis' first chapter (the overview of your thesis) as a framework or outline. Substantive information in your thesis should correspond with your slides.

Make sure your slides are of good quality— both in terms of the integrity of the information and the appearance. If you need more help with how to prepare your presentation slides, both the ASQ Higher Education Brief and James Hayton have good guidelines on the topic.

The committee will ask questions about your work after you finish your presentation. The questions will most likely be about the core content of your thesis, such as what you learned from the study you conducted. They may also ask you to summarize certain findings and to discuss how your work will contribute to the existing body of knowledge.

Tip: Read your entire thesis in preparation of the questions, so you have a refreshed perspective on your work.

While you are preparing, you can create a list of possible questions and try to answer them. You can foresee many of the questions you will get by simply spending some time rereading your thesis.

Here are a few tips on how to prepare for your thesis defense:

You can absolutely prepare for most of the questions you will be asked. Read through your thesis and while you're reading it, create a list of possible questions. In addition, since you will know who will be on the committee, look at the academic expertise of the committee members. In what areas would they most likely be focused?

If possible, sit at other thesis defenses with these committee members to get a feel for how they ask and what they ask. As a graduate student, you should generally be adept at anticipating test questions, so use this advantage to gather as much information as possible before your thesis defense meeting.

Your thesis defense is a formal event, often the entire department or university is invited to participate. It signals a critical rite of passage for graduate students and faculty who have supported them throughout a long and challenging process.

While most universities don't have specific rules on how to dress for that event, do regard it with dignity and respect. This one might be a no-brainer, but know that you should dress as if you were on a job interview or delivering a paper at a conference.

It might help you deal with your stress before your thesis defense to entrust someone with the smaller but important responsibilities of your defense well ahead of schedule. This trusted person could be responsible for:

• preparing the room of the day of defense
• setting up equipment for the presentation
• preparing and distributing handouts

Technology is unpredictable. Life is too. There are no guarantees that your Powerpoint presentation will work at all or look the way it is supposed to on the big screen. We've all been there. Make sure to have a plan B for these situations. Handouts can help when technology fails, and an additional clean shirt can save the day if you have a spill.

One of the scariest aspects of the defense is the possibility of being asked a question you can't answer. While you can prepare for some questions, you can never know exactly what the committee will ask.

There will always be gaps in your knowledge. But your thesis defense is not about being perfect and knowing everything, it's about how you deal with challenging situations. You are not expected to know everything.

James Hayton writes on his blog that examiners will sometimes even ask questions they don't know the answer to, out of curiosity, or because they want to see how you think. While it is ok sometimes to just say "I don't know", he advises to try something like "I don't know, but I would think [...] because of x and y, but you would need to do [...] in order to find out.” This shows that you have the ability to think as an academic.

You will be nervous. But your examiners will expect you to be nervous. Being well prepared can help minimize your stress, but do know that your examiners have seen this many times before and are willing to help, by repeating questions, for example. Dora Farkas at finishyourthesis.com notes that it’s a myth that thesis committees are out to get you.

Two common symptoms of being nervous are talking really fast and nervous laughs. Try to slow yourself down and take a deep breath. Remember what feels like hours to you are just a few seconds in real life.

• Try meditational breathing right before your defense.
• Get plenty of exercise and sleep in the weeks prior to your defense.
• Have your clothes or other items you need ready to go the night before.
• During your defense, allow yourself to process each question before answering.
• Go to dinner with friends and family, or to a fun activity like mini-golf, after your defense.

Allow yourself to process each question, respond to it, and stop talking once you have responded. While a smile can often help dissolve a difficult situation, remember that nervous laughs can be irritating for your audience.

We all make mistakes and your thesis defense will not be perfect. However, careful preparation, mindfulness, and confidence can help you feel less stressful both before, and during, your defense.

Finally, consider planning something fun that you can look forward to after your defense.

It is completely normal to be nervous. Being well prepared can help minimize your stress, but do know that your examiners have seen this many times before and are willing to help, by repeating questions for example if needed. Slow yourself down, and take a deep breath.

Your thesis defense is not about being perfect and knowing everything, it's about how you deal with challenging situations. James Hayton writes on his blog that it is ok sometimes to just say "I don't know", but he advises to try something like "I don't know, but I would think [...] because of x and y, you would need to do [...] in order to find out".

Your Powerpoint presentation can get stuck or not look the way it is supposed to do on the big screen. It can happen and your supervisors know it. In general, handouts can always save the day when technology fails.

• Dress for success.
• Ask for help setting up.
• Have a backup plan (in case technology fails you).
• Deal with your nerves.

The top 10 thesis defense questions (+ how to prepare strong answers)

Crafting a thesis is significant, but defending it often feels like the ultimate test. While nerve-wracking, proper preparation can make it manageable. Prepare for your thesis defense with insights on the top questions you can expect, including strategies for answering convincingly.

Mastering the thesis defense: cultivate a success mindset

Confidence enables you to present your research with conviction, while composure allows you to navigate any challenges with grace and clarity.

Remember, you know your thesis best, so trust in your expertise.

In essence, a success mindset encompasses the belief in your abilities, coupled with the ability to remain calm and focused under pressure.

Stay composed and focused, relying on your thorough preparation. If you encounter a question you can’t answer, gracefully guide the conversation back to familiar topics.

By embracing these principles and staying confident and adaptable, you’ll navigate your thesis defense with ease.

Question 1: Why did you choose this particular topic for your research?

This question delves into the origins of your academic journey, aiming to understand not just what you studied, but the underlying motivations and processes that drove your exploration. It’s not merely about the superficial aspects of your research, but rather about the deeper intellectual curiosity that ignited your quest.

Moreover, discuss the gaps you identified in the existing literature that motivated you to contribute to your field. What deficiencies or unanswered questions did you observe? How did these gaps inspire you to embark on your research journey with the aim of filling these voids? By articulating the specific shortcomings in the current body of knowledge, you demonstrate a nuanced understanding of your research area and underscore the significance of your work.

Question 2: How does your research contribute to the existing body of knowledge?

This question delves into the vital role your research plays within the existing body of knowledge, urging you to articulate its significance and impact. It’s not merely about the subject matter you’ve studied, but also about the unique contributions and advancements your research brings to your field. To effectively respond, delve into the intricacies of your work and its implications for the broader academic landscape.

Illuminate how your findings could influence future research trajectories. Explore potential avenues for further inquiry that emerge from your research findings. Consider how your work opens up new questions or areas of exploration for future researchers. By identifying these potential research directions, you demonstrate the forward-looking nature of your work and its potential to shape the future trajectory of your field.

Question 3: What are the key findings of your research?

Furthermore, relate these findings to the broader implications they hold for your field. Articulate how your research contributes to advancing knowledge or addressing pressing issues within your academic discipline. Consider the potential impact of your findings on theory, practice, or policy, highlighting their relevance and significance within the larger scholarly community.

Question 4: Can you defend your research methodology?

Defending your research methodology entails a comprehensive understanding of its rationale, alignment with research objectives, and acknowledgment of potential limitations. It’s not merely about explaining the methods employed but also justifying why they were chosen over alternative approaches. To effectively respond, delve into the intricacies of your methodology and its implications for the study.

Be prepared to discuss the limitations inherent in your chosen methodology and how you mitigated them. Acknowledge any constraints or shortcomings associated with the selected approach, such as potential biases, sample size limitations, or data collection challenges. Demonstrate your awareness of these limitations and discuss the strategies implemented to address or minimize their impact on the validity and reliability of your findings.

Question 5: How did you analyze the data and what challenges did you encounter?

Begin by outlining the techniques used for data analysis. Describe the specific methods, tools, and software employed to process and interpret the data collected. Whether it involved quantitative statistical analysis, qualitative coding techniques, or a combination of both, provide insights into the analytical framework guiding your study. Additionally, discuss the rationale behind the chosen analytical approach and how it aligns with the research objectives and questions.

In summary, when addressing inquiries about data analysis, consider the following key points:

Question 6: What theoretical frameworks or references underpin your research?

Elucidate on how these frameworks shaped your hypothesis and analysis. Describe how the theoretical perspectives and insights gleaned from seminal works informed the development of your research questions, hypotheses, and analytical framework. Discuss the ways in which these theoretical frameworks guided your data collection and interpretation, influencing the selection of variables, measures, and analytical techniques employed in your study.

Question 7: How did you address ethical considerations in your research?

When addressing ethical considerations in your research, it’s essential to demonstrate a commitment to upholding ethical standards and protecting the rights and well-being of participants. Responding to inquiries about ethical protocols involves explaining the steps taken to ensure ethical conduct throughout the research process, describing the consent process and data protection measures implemented, and mentioning any institutional review board (IRB) approvals obtained.

Mention any institutional ethics review board approvals you obtained. Highlight any formal ethical review processes or approvals obtained from relevant regulatory bodies, such as IRBs or ethics committees. Discuss how the research protocol was reviewed for compliance with ethical guidelines and standards, including considerations of participant welfare, informed consent procedures, and data protection measures. By acknowledging the oversight and approval of institutional review bodies, you demonstrate your commitment to ethical integrity and accountability in conducting research involving human subjects.

Question 8: In what ways does your research contribute to the field?

Begin by detailing the novel insights your thesis provides. Articulate the key findings, discoveries, or perspectives that distinguish your research from existing literature and contribute to advancing knowledge within your field. Discuss how your study fills gaps in current understanding, challenges established assumptions, or offers innovative approaches to addressing pressing issues, highlighting its potential to generate new avenues of inquiry and broaden the scope of scholarly discourse.

In summary, when addressing inquiries about the contributions of your research to the field, consider the following key points:

Question 9: How did you ensure your research was free from bias?

Describe any blind or double-blind procedures employed in the study. Explain how blinding techniques were used to prevent bias in data collection, analysis, or interpretation. This may involve withholding certain information from researchers or participants to minimize the potential for conscious or unconscious bias to influence the results. Discuss how these procedures were implemented and their impact on enhancing the credibility and impartiality of the research outcomes.

Question 10: Where can future research go from here?

When considering the potential trajectory of your research topic, it’s essential to identify areas where further investigation could yield valuable insights, discuss unexplored questions that emerged from your research, and reflect on the limitations of your study as starting points for future research endeavors. Responding to inquiries about the future direction of research involves suggesting fruitful areas for further investigation, highlighting unresolved questions, and leveraging the limitations of your study as opportunities for future exploration.

Reflect on the limitations of your study as starting points for future research. Acknowledge any constraints, biases, or methodological shortcomings that may have influenced the outcomes or interpretations of your study. Discuss how these limitations provide opportunities for future research to refine methodologies, address confounding variables, or explore alternative theoretical frameworks. Consider how addressing these limitations could enhance the validity, reliability, and generalizability of future research findings within your field.

Defending a PhD thesis like a boss!- an in-depth Guide

A thesis defense is a two-way process of PhD evaluation, a session during which experts ask questions related to the PhD dissertation for awarding a PhD degree.  

Defending a PhD thesis or dissertation is the last station of the PhD. The process of a doctorate is different! Even though prospective candidates don’t need to appear in the written examination, the thesis defense is a must!

It’s a process occurring behind closed doors or openly (sometimes!), under the supervision of subject experts or all, to award someone a prestigious doctor of philosophy degree .

PhD- the Philosophia doctor is a path full of complications and problems. Starting from admission to writing a thesis or viva, a candidate has to achieve every milestone to move forward towards a PhD. 

Broadly, a good graduation or master’s score, completion of the entrance exam, course work, PhD thesis, publication in a peer-reviewed journal, PhD presentation and well-completed PhD research are criteria to appear in the PhD defense. 

If a candidate fails to achieve any of the requirements given above, he or she can’t go-ahead. The PhD is all about research, passion, knowledge on one side whilst depression, lack of confidence, loneliness, frustration on the other side, nonetheless, it is a fun journey. 

Defending a PhD thesis at terminal can relax a doctoral student, although should not be taken for granted. 

The present piece of content is all about defending your PhD thesis, what is it and how to appear. I will also give you some tips that help you to successfully complete it. 

What is a thesis defense? 

The thesis defense is the terminal process of discussing ‘research’ to award the PhD degree. It is also referred to as PhD viva too; however, it is more a discussion session than a viva. 

A prospective student has to appear in the thesis defense along with the PhD thesis, a presentation and all other PhD related documentation. A student also has to carry all the materials and proofs that can be used to convenience a supervisor or expert to award the doctorate. 

The entire process is verbal. Two external subject experts, a guide, and a university VC conducts the process, note that other students can also appear in the PhD defense process too as a guest. 

Universities usually conduct close viva sessions to avoid ‘personal bullying’ during the thesis defense. 

During the process, questions are based on the thesis content, topic and subject of the prospective student’s research. The objective of conducting the defense session is to check the knowledge of a student, research aptitude and how he or he had done their research. 

It is a kind of evaluation process in which experts ask questions and point out gaps in research presented by a student.

What is the process of thesis defense? 

The process of PhD thesis defense starts with the general introduction of experts followed by the presentation session. A candidate has to present their thesis in a PowerPoint presentation, keynotes or google slides. 10 to 20 minutes are alloted to present the work in 15 to 25 slides. 

Soon after, experts ask questions related to research. Several of them are, 

What is the purpose of the present research? 

Why is the present topic chosen? 

What is the study population and why only those are selecting 

What are the outcomes of the present work? 

Why are the results or outcomes important? 

What are the societal benefits of the present work? 

How or what the present research contributes to the present knowledge? 

These are the common questions asked to know the quality, quantity and strength of the research one has conducted. 

The process is of two types; close thesis defense viva and open thesis defense viva. 

In the close thesis defense viva, only a subject expert and a PhD supervisor conduct the entire process of the thesis defense, no one is allowed to interfere in it. A student can defend their thesis confidently, on the positive side, however, sometimes the integrity of the session doesn’t maintain due to lack of a monitoring body. 

During the open thesis defense, anyone can appear in the viva session including students of master’s and graduation. Also, anyone can ask questions related to the topic. 

Open thesis defense sometimes makes things harder for the prospective student. Which type of viva or defense system you have to face will depend on the university. The process and type of thesis defense vary from country to country and university to university.  

2 to 5 examiners or external evaluators are invited for a PhD thesis defense session by the university. The criteria to select examiners for the same are; they should be not from the university, they are experts in a related subject, they are working outside the university. 

University allows a PhD supervisor to the defense session but they can’t participate in the discussion. Examiner examines the thesis and will randomly ask queries to the presenter. 

Who conducts a thesis defense? 

The thesis defense of master’s, M Phil or PhD is held by the university under the vigilance of the supervisor for the student appearing in the degree. 

A PhD supervisor invites two or three other experts of the subject to conduct the session, university presentative or vice-chancellor closely monitors the entire process, if present.

How long a thesis defense occurs? 

Per student 10 to 20 minutes are allotted to defend the thesis, however, it may vary, depending on how long a verbal questioning session happens. If it is interesting, it may take up to 2 hours. 

Sometimes, experts wind things in 30 minutes too; that depends on how neatly you have written your thesis and how beautifully you have given your presentation. Still, a few questions are common and asked in every thesis defense. 

Usually 20 minutes to 2 hours it takes to complete the thesis defense. 

What happens after the completion of the thesis defense? 

Defending a thesis isn’t like giving a written exam, which means the results are not like ‘pass’ or ‘fail’. The results are like how excellently one has done their doctorate- research, thesis and presentation. 

There are three possibilities after completing the PhD viva or thesis defense.

• First, you have successfully completed it.
• Second, you have failed in defending the thesis- revision required. 
• Third, there are chances of improvement- minor revision required. 

When you present your thesis excellently, write the dissertation in a proper way and accurately- like a professional writer, proofread it correctly, complete all the objectives mentioned in the thesis, done research in a proper way, you probably come in the first case. 

A PhD degree will be awarded to you soon! 

If a thesis is not written in a good way, not all the objectives are completed, not published a paper, or fails to write a thesis completely or it is partially incomplete, you fail in defending the thesis, need revision.

In this case, you have to re-appear in the Ph.D. to complete the incomplete work. 

The third case is a bit different in which a student is advised to do some minor changes and improvements to make their own thesis much better. Usually, re-viva is not conducted in these cases. 

In the second case, in which a student fails to defend their thesis, re-viva and second round of thesis defense will be conducted after six months or a year. 

Note that awarding the thesis entirely depends on the external examiner.

Can anyone fail in the thesis defense? 

I can say yes! But not exactly because it is not an examination. A candidate has to appear again after sometimes to defend the thesis. Here are the cases in which we can say, a candidate failed thesis defense.

• Improper, incorrect or partial thesis. 
• Incomplete objectives. 
• Incomplete research work. 
• Lack of significant outcomes. 
• No publication 
• Fail to answer questions during the defense. 

Practically it is not considered as ‘fail’, re-viva or another round of thesis defense will be conducted. 

Tips to successfully defend the thesis for PhD: 

When you will be on your presentation, an examiner opens your thesis; thoughts of curiosity, nervousness, excitement and energy will flow around you, all at once. 

In these conditions, even if your preparation is excellent, a small mistake can ruin everything for you. 

You have to balance your positive as well as negative emotions at the same time. Here are some of the tips that definitely help you to defend your PhD thesis successfully. 

Fill yourself with positivity: 

You are very near to your goal, one step ahead of getting a degree- an utmost academic honor- the PhD. Surely, you need to balance everything, as I said, but to do so, you need to behave positively. 

Even if you know the gaps, problems, limitations and problems of your PhD thesis, yourself or your knowledge, you need to keep calm and behave like everything will be on your side. 

Only you know what is not perfect in your presentation or thesis, why to show it to others! Stay calm, focus, confident and positive like everything is perfect there. 

If you still feel so negative, imagine there are so many students in the world who have not even reached this level! You are here, on the last step of the PhD- feel proud of yourself.

Dress well, look well: 

To feel confident and positive, you have to look better. Wear a good, decent and formal dress, shave your beard or trim it, style your hair and polish your shoes. If you will look good, a positive and joyful atmosphere will be constructed in the room that will definitely help you. 

Don’t look tired, hopeless, restless, sleepless. 

Checklist all things: 

A couple of things are required during the PhD viva or thesis defense session. One is the presentation and the second is the thesis. In addition to this, don’t forget to take other documents related to your PhD like your plagiarism clearance certificate, your registration certificate and even your logbook. 

One can’t appear in the thesis defense session without a presentation and thesis. 

Other things are secondary in this case. 

Also read: How to Avoid Plagiarism in Your PhD Thesis?

Prepare a good presentation: 

Before preparing a PhD presentation, you need to know in which format the university allows to present the thesis. However, the globally accepted format is Microsoft Powerpoint. 

Prepare a good, decent and professional PhD presentation of 10 to 15 slides and save it in multiple formats. Include only necessary information, I know it is very difficult to summarize the 4000 to 5000-word essay in 10 slides. 

Also, don’t forget to include material, methods, theory, results and outcome of the research, those things are very essential. Make your presentation correct with your PhD supervisor before appearing in the thesis defense. 

Make a backup: 

What if your presentation will not run on the day of defending the thesis? What if you lost your hardcopy of the thesis? that is not good, right! 

 You are a PhD student , above all, out of the box thinking ability and good analytic thinking, how can you forget to make backups? 

Backup your presentation in a flash drive, cloud storage and email. Prepare presentations in multiple formats.

Make the back of the thesis soft copy as well and store it on different devices that are easily accessible in case of emergency. In addition to this, also prepare a rough and unbounded draft of the thesis hardcopy as a backup. 

Control yourself: 

Students who have done their PhD sincerely are confident about their work but it is very important to control yourself during the thesis defense. In any harsh condition don’t lose your calm, don’t be aggressive.

Even if you know that the expert is wrong- that is a rare case scenario, respect their opinion and behave accordingly. See it is obvious, no one knows more than you and your guide about your topic.

Try to explain things to the panel member, if it can’t work, leave it, respect their opinion and take it as suggestions. 

Read more: 10 PhD Programs You can choose to Study- A Comprehensive Guide .

Answer to the point: 

Sometimes it happens that you explain things more than the experts’ needs. There are drawbacks of explaining things elaborately, they can trap you! 

As I said, pay attention to the question asked by the expert and try to answer what they want, not more than that. Explain things if they don’t understand. 

Do this if you don’t have an answer: 

Experts’ duties are to find gaps and problems in your research so that they can find knowledge actually required. So it is obvious, they confuse you, and ask questions which you don’t know. 

 Don’t get nervous or panic, if you don’t know the answers. Take a deep breath and admit that you don’t have the answer or don’t have an idea about that. To support this situation, you can even make an assumption that this might happen or this will be the reason or give a probability.

See thesis defense is not like a viva, questions will be intellectual and will challenge your knowledge and thinking every time for sure. You have to show them your ability to think differently, not what to already know! 

Also read: 50 various PhD degree full forms .

Do this if something wrong happens! 

Days change, some are good, rest are bad. Things will be on your side someday, or not on other days. What you will do if something wrong happens whilst defending the thesis? 

Your presentation may not work, You lost your thesis, a big problem with the thesis- you didn’t know and problems in findings of results; these are some common problems I had seen in PhD viva. 

So you have to prepare for that, what to answer in those conditions. Anyone can make mistakes, simply apologize and request panel members that you will fix the problem soon. See, you have to act as per the situation, I can not tell you what you say in which conditions. 

For instance, if your presentation is not working or electricity is not there on the day of the presentation simply apologize for that, present it with the available utilities like chalk and blackboard.

The important thing is don’t panic, apologize first, and request to continue the presentation. For instance, if there is a major issue in the thesis, request the examiner that you will fix it, please allow you to continue the presentation. Try to complete your presentation, anyhow, who knows if they will impress. 

Be prepared for the most common questions: 

 The 10th tip is very useful and kind of a hack for you. There are several questions asked routinely during every thesis defense session. For instance,  what is the purpose of your research? How outcomes help society? Why have you chosen this topic? Why have you selected this technique for your work? What are the applications of your research? Like that. 

Be prepared for these questions, a few of them will be asked during the session. Then after the discussion will pick the heat, and your thinking ability will be tested.

Conclusion: 

Thesis or dissertation and PhD viva or thesis defense aren’t mandatory for all. Some professional degrees seek only internships for the award of PhD or doctorate. IN PhD in medicine or psychology, thesis or viva isn’t conducted, though the criteria are decided by the universities and hence vary greatly. 

Still, the thesis defense is a common practice performed to award PhD, M Phil or post-graduation degree.

Definition: Thesis defence

A thesis defence is an act of presenting your work to a panel of professors so they can grade your presentation abilities. In retrospect, the argument is essential to ascertain that you understood the topic. You have to hand in your paper first so that the lecturer can grade it before you appear for the defence.

As a university student, you need to hand in a high-quality thesis paper and defend it before a panel of professors. So what is this that takes place during a thesis defence? Read along to find out.

In a Nutshell

So, there you have it. These tips should help you present your thesis defence and ace it. Remember that:

• You should present facts that are in the paper. Do not add any new information
• Make the thesis defence as enjoyable as possible
• Arrive early enough
• Do not exceed your allocated time
• Confidence goes a long way
• ✓ 3D live preview of your individual configuration
• ✓ Free express delivery for every single purchase
• ✓ Top-notch bindings with customised embossing

Before the Thesis defence

Before the day of the thesis defence, the qualifying students receive a timetable that shows the chronology of how the day will be. You are required to keep time, or else you will have to wait until the next allocated defence to present your paper. To qualify as a defending student, you have to hand in your paper at least one month before the thesis defence date.

What happens in a Thesis defence?

Once you get to the hall, you need to introduce yourself and your topic, then present your paper to the lecturers. The professors will allocate you ¾ of the allotted time for the thesis defence. The remaining time is used up in the question and answer forum. Prepare yourself to answer several questions, such as:

• Your plans after completing the research
• The limitations you faced
• Things that you would change if given a chance
• How you chose your target audience
• How you intend to further your study on the subject
• The reasons for choosing your topic
• The most significant deductions you learnt from the survey
• Reasons for choosing your research methodology, etc.

In some cases, the board may ask you to summarize your deductions from the study. The questions asked are not standard, which nastys you have to be thoroughly prepared to answer whatever the panel throws your way during the thesis defence. Other things that take place during the thesis defence include:

• Deliberations – At this point, the board of lecturers will ask you to leave the room as they deliberate on your thesis defence performance. They will then decide whether you move to the next level or you will defend again.
• Verdict – Finally, the team will invite you back in and tell you how you performed in the thesis defence. These panel members may ask you to make a few corrections before you can go ahead and publish your paper. You have to present your corrections to your facilitator, who will then give you the go-ahead to publish.
• Signing – The members will then sign your document to ascertain that you were part of the thesis defence team on the selected date.

How much time does a Thesis defence take and how many people should be in the room?

During a thesis defence, each student appears before the panel individually. The facilitators will ask you questions concerning your topic to see if you fully grasped the concept. Each thesis defence will vary from the other depending on the technicality of your paper and the kind of degree you are pursuing.

• Undergraduate degree – Your panel may include at least three lecturers from your staff. Additionally, the defence may last up to one hour.
• Masters degree – You get to interact with four professors at this level, and each student is allotted 1½ hours to present and answer questions.
• Ph.D. degree – Considering that this is the highest education level, five professors avail themselves to vet you. More so, you may have to engage them for two hours.

What to include?

A thesis defence follows a particular format, which cuts across all types of degrees, which is:

• Introduction  – Explain the need for this study
• litreature review  – Explain what other scholars have found on the subject
• Research methodology  – What research method did you use, and why did you use it?
• Findings and discussions  – In your research, what were the key deductions that you came upon?
• Implications, limitations, suggestions, and  conclusion  – Here, you have to exhaust the setbacks you encountered during the study, the consequences that your target audience will face if they do not follow the deductions, and then finally sum up the discussions.

Tools for Thesis defence

Considering that a thesis defence may take you at least 45 minutes to present, it is essential to make the presentation lively. So, you can incorporate a slide show and use images to make it less wordy. Bullet points also make the text easier to digest as opposed to a block of text. So, a laptop and a projector will help you ace your presentation.

Thesis defence Anxiety

Standing before a panel of people waiting to hear how you conducted your research can be intimidating. This is especially so considering that you will be standing before a group of professors, who you believe to be superior to you in regards to the topic knowledge. More so, if you are not familiar with public speaking, it is easy to develop stage fright while defending.

Manage Thesis defence Anxiety

In case you find yourself fidgeting before you begin presenting, use the following tips to help you get your composure back.

• If you have a problem with eye-balling the lecturers, look at the tips of their foreheads instead.
• Take a few seconds to breathe in and out so you can stabilize your speech if you begin to stammer.
• Go into the room with a positive mind, knowing that you will do your best.
• Most importantly, rehearse your thesis defence severally before the D-day.

What is a thesis defence?

A scholarly thesis defence is a forum that allows students to present their paper’s contents and defend their thesis topic before a panel of professors. The student is then required to answer all questions asked by the lecturers. At the end, the student is required to leave the room whilst the professors decide whether the thesis is ready to be published, or if it needs corrections.

How long is a thesis defence?

There is no general length for a thesis defence. The defence of a master’s thesis will take longer than the defence of a bachelor’s thesis. You will need to fit in an introduction , a litreature review, your findings and even more into the time frame for your thesis defence, so it’s important that you’re well prepared. All in all, it depends on your paper and your academic field. Usually the thesis defence will last between one and two hours, but it also could be less than one hour.

What is the oral defence of a thesis?

Oral defence is simply another name for your thesis defence. If you’ve completed your thesis, you are required to defend it in front of a panel of professors. It is designed so that the committee can ensure that the students completely understand their thesis topic . The oral thesis defence is an examination of a completed body of work. Students will be assigned a date to defend their thesis.

What happens after the thesis defence?

After your thesis defence, you will be told to leave the room whilst the panel discusses your results. There are normally 2 outcomes. You may need to make changes to your thesis’ formatting or content. If this is the case, don’t stress! You’re able to try the thesis defence again once you’ve incorporated any required changes. The preferred outcome is that the panel is happy with your thesis and it’s then ready to be signed and published.

What defines a good thesis defence?

The thesis defence is the final step for your academic work. It’s important that you’re prepared and you’ve outlined what you’re going to say in each section of the defence. You need to know your thesis statement better than the back of your hand, otherwise you risk being sidetracked. Just like your thesis itself, your thesis defence has a specific structure. You can read more about this further on in the article. Try and prepare yourself for the potential types of questions that the professors will ask you so that you don’t have to think about your answers on the spot.

The dreaded doctoral defense

An oral defence, or Viva, is common in the UK, Europe, NZ. The viva is less common in Australia.  Most Australian students will do a final presentation before the PhD, but many universities are currently discussing how to introduce a defence as part of the examination process, so we can expect a defence of some sort to become more common.

In the USA, the viva is called a ‘doctoral defense and PhD students have the additional challenge of being examined by their supervision committee. The US system is so different I don’t tend to write specific posts to address the various challenges because I don’t have any first hand experience, so I’m always grateful when a US colleague offers to write one.

This post is by author, editor, writing coach, dissertation nurturer, and spiritual counselor, Noelle Sterne, Ph.D. (Columbia University). She has published over 400 academic, writing craft, and spiritual articles and stories and essays in print and online venues. She delivers workshops and presentations to university faculty and writers and assists doctoral candidates in completing their dissertations (finally). Her handbook addresses these students’ largely overlooked but extremely important nonacademic difficulties: Challenges in Writing Your Dissertation: Coping with the Emotional, Interpersonal, and Spiritual Struggles (Rowman & Littlefield Education, 2015). In Noelle’s first book, Trust Your Life: Forgive Yourself and Go After Your Dreams  (Unity Books, 2011), she helps readers release regrets, relabel their past, and reach lifelong yearnings. Website:  www.trustyourlifenow.com .

This post is adapted from: Challenges in Writing Your Dissertation: Coping With the Emotional, Interpersonal, and Spiritual Struggles , chapter 7 – “The Dreaded Doctoral Defense”.

Almost everyone who has a doctorate has a final defense story. They may be different but they all have two things in common: few are pretty and theyíre emblazoned on the new doctor’s mind forever.

A friend of mine was obviously pregnant at her defense. After she successfully passed, her chair (supervisor), staring at her bulk, informed her with a tone of incontrovertibility that her entire graduate education had been a ‘waste’. Outrageous and maddening, I know.

Happily, she proved the chair monumentally wrong. Later, with two kids, she became an award-winning professor at Brandeis.

My defense was a little less dramatic but no less discomfiting. During the two hours of grilling and false camaraderie, my right foot fell asleep. As I rose for the verdict, my leg collapsed and I almost fell over the table into a bald committee member’s lap. They all laughed, almost as embarrassed as I. I still blush reliving it.

A fellow student in my doctoral cohort, by far the most brilliant of us all, felt he did so poorly at his defense that he cancelled a long-planned prepaid vacation to Scandinavia with his fiance. I never heard whether he ever went on the trip got married. This was mea culpa at its worst.

What do these cautionary tales tell you? To see your defense rightly. A rite of passage, certainly, it is nevertheless an important event in your progress and professional development. You don’t want to fail or flub it. You also want to maintain dignity and engender the respect of your chair and committee members’ your future colleagues.

As a consultant and coach to dissertation writers, I have often noticed that most candidates are petrified of the defense and either overdo it or try to underplay it. They imagine the committee asking impossible questions, like a detailed explanation of their statistical involutions, or asking ridiculous questions, like their opinion of the university cafeteria food.

Many candidates either spend every possible moment cramming, and risk predefense burnout, or avoid preparation entirely. James started preparing before he had even completed his data collection. He kept asking me questions about the required procedures and sent me loads of articles on defense advice, confessing he kept losing sleep panicking about his defense. I gently told him, several times, that his preparation, although admirable, was premature.

At the other extreme, Viola, a very bright candidate, told me years later that, despite my admonitions, she had minimized her defense and barely squeaked by. She knew the material but her nervousness and lack of preparation got the best of her. She regrets to this day not following my advice.

Recognizing that both extremes are, well, extreme, I developed the following suggestions for a good final defense before, during, and after the event. First, though, for your greater perspective, especially in U.S. defenses, some words about your committee.

Your Committee

Doubtless all members have their own defense horror stories, and your defense may trigger echoes of theirs. Their egos are at stake in your meeting, and they probably want to show off to each other. They also may want to show off by asking you tough questions. And yes, they may be unpredictable, quirky, mercurial. But remember that they are also upholding the high research standards of the university and their part in it. Keep in mind too that they have worked hard to get where they are. Theyíre not your enemies and want you to succeed, for you and for them.

So now, for you to make the experience a pleasant one for everyone, some advice on preparation.

Way Before the Defense

It’s better to be overprepared than underprepared. You will thank yourself for it later. Remind yourself that you are the expert on your dissertation, especially every time your stomach sinks. Read the university manual on defense protocols. It should tell you the time allotted for your introductory presentation, if you need a PowerPoint presentation and the number of slides, and whether the defense will be open to the ‘public’ (usually friends, family, and a few stray predefense doctoral students). Attend several defenses before your own to familiarize yourself with the process. Observe how the candidates respond, and make notes on the positive behavior (poise and direct eye contact with the committee) and negative behavior (a lot of ìuhs,î ìahs,î and slouching). Youíll be combating your fear of the unknown. Ask your chair for advice. About a month before the defense, schedule a meeting and discuss the defense format and range of possible questions. Ask the chair to look at your PowerPoint beforehand (they often want to and will critique it) and ask too for (diplomatic) insights on the committee members. If trouble erupts, such as another member calling for your running your statistics completely again or insisting that you ‘need’ to survey 132 more dock workers, the chair is supposed to fight for you (diplomatically).

Especially if other candidates have had your chair, study their final PowerPoints. When youíre ready for your own, use these and any outlines in the doctoral manual. Creating the new slides from your dissertation will help you remember, review, and summarize everything.

Think of the worst questions you donít want to be asked. Write them all down.

Type out your answers. You can refine them later. Make sure your dissertation backs up your answers (for example, correct number of participants, statistical results, themes revealed).

Know your material! Some candidates mark a hard copy of their dissertation at the pages reflecting anticipated questions. If you do, you can turn to the pages quickly. Alternatively, use the PowerPoint’s space at the bottom of each slide for your notes and scripts.

Rehearse with a relative or friend (something you can involve them in, and theyíll be tickled to help).

A Little Before

If your university has a media specialist, schedule an appointment for your electronic needs for the PowerPoint and have a list ready.

Visit the room in which the defense is scheduled, preferably with the media specialist, and plan together where you’ll place your computer and other equipment.

Alone in the room, do a mock rehearsal. Stand at the podium and look out into the vast sea of faces eager for your wisdom. See the chair and committee members sitting there beaming at you.

A few days before, decide what you’ll wear (even if the defense is by teleconference). Choose clothes that look and feel professional and get them in shape.

The day before, pack your materials: computer, flashdrive backup, hard copy, handouts, pens, pencils, recorder/phone app if you choose, and anything else that anticipates any technical malfunctions and may seem like overkill but will make you breathe easier.

Don’t forget the deodorant.

The night before, go to the movies, binge watch your favorite TV show, or do something physical. No alcohol. Get a good night’s sleep.

Arrive early and meditate beforehand either in your car, on a bench outside, or even in the empty room.

Reflect on your previous successful presentation experiences’ from your job, a speech at a wedding, an impassioned piece of advice to a friend who took it.

Set up your materials.

Tell yourself you are confident and passionate about your topic and findings.

When they enter, SMILE.

Stand up, stand straight.

Greet each committee member, even if your knees are shaking.

Look ’em in the eye.

Remember that you are the expert. Take a few deep breaths.

When the committee starts asking questions, have a notepad and pen ready to take notes, and take your time responding.

If you don’t know an answer, don’t fudge. Instead say, “That’s a very good question. I’ll have to think more about it” or “I’ll do more research on that.” Remember you are still the humble student. The committee will admire your response.

At the end of the defense, smile, shake hands (admittedly clammy), and thank everyone profusely. Tell them you enjoyed the meeting (it is possible).

Expect some revisions. Just because it’s the ‘final’ defense doesnít mean the committee can’t change its collective mind and swoop down on niggling and not-so points.

Collect the committeeís hard copies with their notes, if this is the procedure. Or offer to pick them up or ask them to email you their marked-up copies or lists of revisions.

Study up on all the red-tape requirements and regulations for revised documents, all committee signatures, and final deposit of the dissertation. You don’t want to miss any deadlines.

Throughout: A Few Helpful Affirmations

• Every time panic hits, practice defensive affirmations:
• I am perfectly competent, confident, express, poised.
• I am in command of myself.
• I look forward to sharing what I know and have learned.
• My defense goes perfectly.
• The committee is for me.
• I trust my knowledge, good work, and good mind to come up with the right answers.
• I know everything I need to know, instantly.
• I now visualize the movie of my perfect defense. I see myself poised and self-assured, talking easily about any aspect of the work, adlibbing from the PowerPoint. I graciously accept all compliments about the brilliance of my presentation. I hear the chair’s magic words, “Congratulations! You have passed!”

* * * * * * When you practice the steps here, you will be one of the few new Doctors without a defense horror story. Your story will be a much happier one, and as you continue in your successful professional career, your defense will shine forever bejeweled in your memory. © 2017 Noelle Sterne

Thesis & Dissertation Preparation

At the University of Kentucky, Master's degrees (Plan A) require the completion of a thesis. Doctor of Philosophy and Doctor of Education degrees require the completion of a dissertation. The Doctor of Musical Arts degree requires the completion of a project. This work reflects the quality of the program that supervises the student and the university that awards the degree. Therefore, the Graduate School sets criteria and standards for the format of the written work which will be available not only to the immediate campus, but also to a wider scholarly community via the Web. Each program has selected the style manual(s) most consistent with scholarly practice in their specific discipline. The student should consult with the Director of Graduate Studies concerning the manual to be used . Note: the general format specifications contained in the Graduate School instructions take precedence over those in the style manuals used by individual programs.

Since Fall 2013, students no longer have had the option of submitting their thesis or dissertation in the traditional print format. The submission of the work in an electronic form has a number of potential advantages, including greater flexibility for the inclusion of multimedia components, and cost savings on paper.

UK electronic theses and dissertations are available as a stand-alone database . They can also be accessed (along with paper theses and dissertations) via the library's catalog .
