What is a thesis defense?
It is the final oral exam that closes the academic process of submitting your thesis officially.
1. Version: Defending your academic work (Disputation)
As you already understand from the term, it is the moment to defend your academic work in front of an audience that consists of a committee and a small group of guests. The bank (committee) includes your first and second supervisor and the chairman of your Ph.D. examination board. The decision and format of permitting external guests depend on every single University.
It contains an opening part, where the candidate presents all central issues of his work, which is followed by a second part, where questions and comments can be made from the audience.

2. Version: Doing a “Rigorosum”
In some cases, Universities stick to the ancient form of a so-called Rigorosum for their Ph.D. candidates. In that case, you have to prepare two short presentations of around 15 minutes of topics from the same discipline but still, from a different field, which will be followed by an interrogating part of the committee.
What happens at a defense? The three central phases of the process!
The disputation or defense of a thesis is usually divided in two essential official parts and a third closing part.
Opening and Presentation (first phase)
During the first part, the candidate has to present:
- the central questions of the dissertation
- questions and aims (focus or research)
- fundamental concepts (shortly)
- important sources and data material
- ways of analysis
- results of your research
As the time is short, everything has to be presented in a very condensed form.
Discussion and questioning: Disputation (Second phase)
In the second part, the examination board and audience will address general and detailed questions to the candidate that leads to a discussion. The order of questions is moderated by the chair of the examination board:

- first and second supervisor
- members of the board
- other (internal) academics and colleagues
- audience (external academics and non-academic guests)
Conclusion and evaluation (third phase)
To conclude, the chair ends the discussion when the questioning time is completed or when all questions are made. The audience has to leave for some minutes and the examination board comes together for a brief private final evaluation. After that, the final result will be announced.

Ph.D. defense or defence? What´s correct? What´s the difference?
Is there any difference, saying (Ph.D.) defense or defence? No, not at all. In fact, the varied spelling thesis defence or defense is just a question of the country. While the Americans are costumed to talk about the thesis defense, the correct version in British English and also the Canadian spelling is thesis defence.
Don´t worry – the meaning and the general process and what you do at a defence or defense is still the same!
How long is a thesis defense?
The concrete format and length of a thesis defense vary from University to University. In most cases, the opening presentation is around 20 to 30 minutes, followed by a questioning part of 30 to 60 minutes.
