Can a supervisor be the examiner for a doctoral thesis?
Is it acceptable for the supervisor to be one of the examiners for doctoral thesis? Usually the examiners have a right to vote to make the final judgment, but could a supervisor be given such a right too? If there are countries which adopt such a system, can you please mention some?
In most countries, the PhD supervisor is one of the examiners of their student’s doctoral thesis. They are equally responsible for evaluating the thesis and providing a judgement. In many countries, doctoral theses need to be reviewed by additional examiners that might be native or foreign. The thesis examination is also usually followed by a PhD viva or defense presentation. PhD supervisors commonly serve as examiners for this as well.
This practice is followed in most countries for doctoral theses evaluations.
