The students in the school take their Career Aptitude Test (C.A.T.) here, and often experience many ghost attacks, including a ghost lunch lady who doesn't like the school's lunch menu getting changed, a therapist who depresses kids as opposed to cheering them up, and a mummy that wants to take control of the school.
- The school's name is a reference to the 1945 cartoon series, Casper, The Friendly Ghost, the first appearance of the title character, who would appear in many future cartoons and movies over the following six decades.
- As shown in the episode "What You Want", Casper High's school mascot is a raven. Their school colors are red, white, and black.
- The school is very old, the same building seen in 1950's from a flashback in "Splitting Images".
