Rumored? Prof. Gaunt has been the toughest grader on the campus for 500 years! His tests are murder!
You might want to check out Simon Green's tales of Nightside for fleshing things out. Ditto Terry Pratchett's Discworld books if you want to go more comedic.
If this is a typical D&D world AND there is a significant enrollment, this is going to be one of the most dangerous places in the world. Imagine, if you will, what would happen if someone raided the Force Studies Building, only to face a few dozen students who ALL know Magic Missile...and more. And that's just for starters.
Other critters potentially involved in campus cleanup/waste disposal: Otyughs, certain undead, carrion crawlers. Disenchanters may be used to de-magic flawed experiments and student projects before release into the next step of the disposal process.
