Scooby-Doo and the Ghoul School  (1988)

Theatrical Release Information:
Scooby-Doo and the Ghoul School

This 2-hour TV cartoon special was originally syndicated as Scooby and the Ghoul School. That's right, kids: our hero is Hanna-Barbera's favorite timorous Great Dane, the one and only Scooby Doo. This time, Scooby, his somewhat more courageous nephew Scrappy Doo and hygenically challenged human cohort Shaggy take jobs as gym teachers at a highly suspicous girl's finishing school. Locked in the building in the dark of night, the dauntless trio finds themselves in classroom chock full of monsters and ghosts. We suspect that the person behind all this will say something like "I would have gotten away with it-if it hadn't been for you meddling kids." To find out what "It" is, you'll have to see this one for yourself. Ghoul School is part of the Hanna Barbere Superstars 10 TV-movie package. ~ Hal Erickson, All Movie Guide
