Keeping this in consideration, can PhD be revoked?
A university is revoking a student's PhD — but not because of misconduct. It's rare for a university to strip a student of his or her degree, but it does happen — usually, as we've seen, after the university discovers the student committed some form of misconduct.
Secondly, what percentage of PhD students drop out? Roughly 25%, or a quarter, of PhD students drop out before finishing their degree. This number varies, though, from course to course and from country to country. For instance, the dropout percentage of PhD students in the US is higher, roughly 50%, or half.
Regarding this, can your degree be taken away?
Yes. University and college degrees are based on not only your academic integrity, but on some Student Code of Conduct issues, as well. If a university or college discovered that a former student committed plagiarism or other types of academic fraud to “earn” that degree, it can be revoked.
What happens when a degree is revoked?
In short, a degree should never have to be rescinded because a rescinded degree should never have been awarded in the first place. When a school rescinds a degree, they are doing it not to retroactively punish the student involved, but to preserve the integrity of their institution and the degrees it issues.
