Lisa was enrolled here when she decided that she wasn't getting enough out of Springfield Elementary School. The admission fee was high but Marge promised to wash all of the laundry for the academy in return for Lisa being there.
After Lisa finds out that Marge is washing all the uniforms, she drops out of the school. In the school, each student gets their own teacher. The school is a "quiet campus" and has a swimming pool, an observatory and an Imaginatorium.
