Two university proctors, elected annually on a rotating basis from any two of the colleges, are the internal ombudsmen who make sure that the university and its members adhere to its statutes.

They are particularly influential in the running of the university's graduate programmes. Examples of statutory professors are the Chichele Professorships and the Drummond Professor of Political Economy.

Not all colleges offer all courses, but they generally cover a broad range of subjects.
