The school strives to prevent as much as possible drop-out and to make a continuous schedule for the students. If a lesson nevertheless falls out, the students have a Z-hour (self-employed hours). Students of the substructure are then received by another teacher or supervisor. They work in a classroom on their homework. Students of the superstructure spend their Z-hour in the auditorium or media library, or the lesson is received by another teacher or supervisor. The pupils are supposed to stay on the school grounds.
