Witchright Hall
Sabrina's heck-raising cousin Amanda is sent to live in the Mortal Realm for a year. Rather than have her stay at the Spellmans', though, Hilda and Zelda arrange for Sabrina to help get Amanda into a special school called Witchright Hall for maladjusted young witches.
Not on the schedule right now. See Sabrina, the Teenage Witch
