Each student will have two examiners, at least one of whom must be external to the University. Appointment of the examiners is subject to the University’s Code of Practice. It is not allowed for a student to contact the examiners directly before the day of the viva which means it is up to the (usually lead) supervisor to arrange this part of the examination process.
There are four possible constitutions of the oral examination, depending on the examiners and the degree being examined:
One internal and one external examiner
The internal examiner will advise on University procedures and good practice, and therefore must have previous experience of examining doctoral degrees.
One internal and one external examiner, and an internal chair
Where the internal examiner has no previous experience of examining doctoral degrees, or in other circumstances where it is felt appropriate, then we will appoint an internal chair. The chair is present only to make sure the University’s procedures are followed fairly and equitably, and must play no active role in the examination.
Two external examiners, and an internal chair
This is the preferred arrangement for staff candidates, but this arrangement can be used for any candidates where there is a difficulty in appointing an internal examiner who does not have a conflict of interest in the project. Where two external examiners are appointed, an internal chair will be nominated as for the previous case.
Oral examination is not necessary
For an MPhil degree, there is no absolute need to hold an oral examination. Whether or not the oral takes place is at the discretion of the examiners.
