Gravedale High (1990)

Human teacher Max Schneider has unwittingly taken a job at Gravedale High, a school for monsters, near the city of Midtown. Schneider, the only human in the school, presides over a group of ghoulish teenagers that are latest-generation versions of classic movie monsters. Most of Schneider's students are either disruptive, uninterested, and/or unduly self-preoccupied in school, and the class is generally considered disreputable if not uncontrollable (not unlike "the Sweathogs" in Welcome Back, Kotter), the implication being Schneider was hired to teach the class because no monster teacher would take the job.
