You’ve completed your research study, written your thesis, and think you’re done! If only it were this easy. Before you finish with your thesis, there is one last hurdle to overcome: the thesis defense.

What is a thesis defense?

A thesis defense is an opportunity for you to present your research study before other academic professionals who will evaluate the quality of your academic work. While a thesis defense can sometimes feel like a cross-examination in a court of law, in reality, there is no need to fear your thesis defense as long as you are well-prepared. In this article, we’ll talk about how to prepare for a thesis defense, what to expect at the defense itself, and what comes after your defense.

Why do I have to defend my thesis?

At your thesis defense, you will discuss everything you’ve learned with a group of interested examiners who are eager to hear your thoughts.

The fundamental purpose of a thesis defense is to prove that you have mastered your subject and can be considered as a knowledgeable expert in your field, thereby allowing you to graduate successfully. For many students, a thesis is one of the first attempts at conducting original research and demonstrating that you are equipped to function as an independent expert in your field. If qualified academic professionals can assess your work, question your methods and results, and confirm that your study is sound and novel, then you meet the requirements.

The exact format and expectations for your thesis defense will differ depending on the region you study in and your institution’s rules for the thesis program. The thesis defense meeting may have just two or three examiners or may have a whole panel of examiners along with an audience.

If the thought of facing your professors, peers, and parents to present your research study makes you feel dizzy, you aren’t alone. Moreover, a thesis defense is a great opportunity for you to hone your public speaking skills as well as talk about your research study. At your thesis defense, you will discuss everything you’ve learned with a group of interested examiners who are eager to hear your thoughts.

While the format for a thesis defense will vary, as mentioned above, most thesis defenses consist of:

Presenting your research study (using PowerPoint or other similar tools)
Answering questions from your thesis committee
Receiving feedback from your thesis committee

So how can you prepare for it? Let’s talk about some important tips.

Preparing: Before the defense

It is useful to attend multiple defenses and ask others who have gone through the process what it was like.

The best way to prepare for a thesis defense is to attend other defenses at your institution so that you know what to expect. It is useful to attend multiple defenses and ask others who have gone through the process what it was like. Senior students are often happy to provide advice and can give you specific insights about particular examiners as well as details of the administrative process at your institution.

You should also talk to your thesis advisor well in advance of your defense about what to expect. Ask whether you need to shortlist your own committee, how long your presentation should be, and how long the thesis defense will be. The duration of a thesis defense varies by the degree level as well as the institution. On average, expect your defense to be at least an hour long, possibly longer for a Ph.D.

What should my presentation cover and how can I prepare it?

While preparing your presentation, also prepare a list of questions and answers that you think are likely to be asked by your committee.

You will need to prepare a presentation that will cover the details of your research study. It is wise to rehearse this presentation multiple times in advance of your thesis defense so that you will be comfortable when you actually present in front of your audience. While preparing your presentation, also prepare a list of questions and answers that you think are likely to be asked by your committee. If you can, enlist the help of a classmate or friend to be the examiner. They can ask you questions about your research study so you will be able to practice addressing these questions.

One mistake many students make is assuming that all members of their defense committee will thoroughly read their thesis prior to the defense. This is simply not always the case. For this reason, you should make sure your presentation makes sense to someone who has not actually read your thesis. A typical thesis defense presentation gives:

An introduction to the topic
Explains how the study is significant in the field
Covers the main highlights of the methodology and results of the study
Picks out the main points from the discussion and conclusion

What should I do the day before my defense?

Before your thesis defense, make sure you have backups of everything you need saved in multiple formats and multiple locations.

Before your thesis defense, make sure you have backups of everything you need to be saved in multiple formats and multiple locations. Put your presentation and your thesis on a USB drive, email it to yourself, upload it to the cloud, and print it out. Leave nothing to chance: you want to be absolutely prepared to defend your thesis short of an act of God obliterating the venue. In addition, make sure you prepare hard copies (printouts) of both your thesis and slideshow for the committee members. It need not be professionally bound at this stage, but they will appreciate having reference material on hand.

Finally, there are some practical steps to take in preparation for the thesis defense. Choose your outfit in advance (you should dress professionally) and practice presenting in it. You should also make sure you know the exact location of the thesis defense venue. Scope out the venue before your defense, if possible, so you can imagine yourself there while you rehearse. If you are presenting virtually, test all your equipment in advance and have a backup plan in case your internet goes out or your computer suddenly crashes. Most importantly, make sure that you eat well and get proper rest the night before. Don’t stay up late rehearsing last minute in the hopes of improving your chances of passing your defense. You will do much better if you are well-rested and alert.

Time to shine: At the defense

Try to stay calm and remember you are not on trial!

What can you expect on the day of the defense?

Typically, you will enter the room, set up, and begin your presentation once the committee indicates that they are ready. As mentioned above, it is always advisable to bring hard copies of both your thesis and slideshow for the committee. That way, they can easily refer to what you are talking about as you present. Make sure you also bring a pencil and notebook with you to take notes, and some water, because you will get thirsty as you talk.

After you are done with the presentation, the committee members will ask questions. Try to stay calm and remember you are not on trial! Your committee generally wants you to succeed, but they also want you to prove that you really know what you’re talking about. Do your best to answer their questions and never be afraid to admit when you don’t know something. It is much better, to be honest than to be caught lying or making something up during your thesis defense.

After the question and answer session, depending on your institution, you may be asked to leave the room while the committee deliberates. You may also be present while they discuss the merits of your defense and make suggestions for how to revise it. Alternatively, they might adjourn to another room if there is a large audience present. After they deliberate, they will usually thank you for your time, and your defense will be over. At some institutions, they will inform you if you passed right away, while at others, you will find out after a few days.

How does my committee decide if my work is good or not?

In general, you can expect your thesis defense and your thesis as a whole to be evaluated based on the below criteria:

Whether the thesis meets the departmental requirements
Whether the research study is logical and clear
Whether the stated objectives are met in the study
Use of primary and secondary literature
Use of relevant and up-to-date sources
Methodological rigor
Your ability to critically analyze data, facts, relevant literature, and synthesize information into a coherent narrative
Writing quality and flow
The validity of your conclusions based on your data and analysis
The relevance and importance of your research study in the field
Your ability to clearly and coherently present what your thesis is about
Your ability to answer questions about your work accurately and in-depth
Your ability to acknowledge and consider other theories or perspectives and explain why you dismissed one theory in favor of another

In summary, the examining committee want to know:

Did you meet the thesis criteria set by your institution?
Did you perform high-quality research work?
Do you know what you are talking about?

After the defense: What’s next?

After your thesis is approved, you will need to have it professionally bound and then submit copies to your university.

After your thesis defense, you should definitely celebrate and congratulate yourself for all your hard work! Unfortunately, you aren’t quite done yet. Although the committee may notify you about passing, it is also very likely that you will be asked to make some changes to your thesis before you are finally done. You should work with your advisor to finalize and incorporate any comments you received into your work as quickly as possible.

After your thesis is approved, you will need to have it professionally bound and then submit copies to your university. You will also get the chance to order copies for yourself. This process also differs by institution, so make sure you talk to the administration department to figure out what you need to do and when to complete this process.

All in all, while a thesis defense is a scary and overwhelming event, it is also an incredible achievement. Earning your degree is no small feat, and you should definitely feel proud of yourself once you have done it!
