The thesis defense, in most cases, is one of your last tasks for completing your graduate or doctoral degree. The thesis defense is not your dissertation. The thesis defense is the final examination or presentation of your dissertation to your thesis committee.

Prepare for, on average, a forty-five minute presentation and question and answer time. The people usually in attendance are members of your thesis committee and non-members including industry professionals or other faculty. You will have a well rounded and well versed panel as your audience!

The committee will ask questions about your thesis and your research and ultimately let you leave from your thesis defense with a Pass with minor revisions, a Pass with major revisions, or simply fail you (I know this won’t happen to you!) . This is a lot of pressure, so how can you make sure that you are prepared? The first is that most people just get so nervous to get up and speak in front of a panel. The best way to prepare yourself and overcome this kind of stage fright is to know your material inside and out.

Be confident in your knowledge and your research. You know your own research, but review it often, and practice your thesis defense with your peers. Letting your peers ask you questions about your research allows you to practice phrasing your answers, but also gives you time to review additional information if you are unsure of an answer. The point is to go into your thesis defense feeling confident about your knowledge. There is no need to scare yourself if you aren’t confident about your speaking skills, if you are confident about your knowledge it will show through in your speaking skills naturally and without hesitation.

Make sure to plan ahead. It will most likely be your responsibility to schedule the time and place for your thesis defense and make sure all the appropriate people are available and aware. You will also have to give a copy of your thesis to the committee well in advance so they have a chance to prepare as well. Review your university guidelines and procedures for scheduling your thesis defense so you can make sure you have everything covered.

Prepare the appropriate presentation materials. You do not need to over pack your bag with visual aids. You’ll want to bring any charts, tables or graphs from your thesis that will help support answers to questions. Bring extra blank transparencies that you can use to demonstrate problems or whatever your study might be. Colored pens are your friends! Bring those along as well to help with diagramming solutions and answering questions visually.

Dress nice and professional for your thesis defense, but make sure you are comfortable.
Practice, practice, practice with your peers and advisors. This, again, will help you best prepare for a lot of different types of questions you might encounter and also help you practice the flow and delivery of your presentation.

The key is confidence in your knowledge! Preparation will help you achieve that, and you should be fine. Good luck!
