The lecture(s) must be of a high academic standard, but communicated in such a way as to be followed by an audience with the knowledge equivalent to that expected among advanced students of the subject. The lecture will last for 45 minutes.
The title of the trial lecture must be announced to the PhD candidate, a minimum of ten working days prior to the lecture. The topic of the lecture must not have a direct connection to the topic of the thesis, but shall help to document the candidate's academic breadth within the chosen field.
The trial lecture must be approved before the public defence can be held. The faculty decides whether the trial lecture will be held separately or on the same day as the defense.
Procedures related to the trial lecture are further described in Regulations § 20.01 Trial lecture, and also in the Guidelines for the Evaluation of Norwegian Doctoral Degrees.
