Dissertation

Thesis examinations

One of the requirements for certain advanced degrees is often an oral examination (called a viva voce examination or just viva in the UK and certain other English-speaking countries). This examination normally occurs after the dissertation is finished but before it is submitted to the university, and may comprise a presentation (often public) by the student and questions posed by an examining committee or jury. In North America, an initial oral examination in the field of specialization may take place just before the student settles down to work on the dissertation. An additional oral exam may take place after the dissertation is completed and is known as a thesis defense or dissertation defense, which at some universities may be a mere formality and at others may result in the student being required to make significant revisions.
