In Saxony, almost every tenth lesson was canceled in the past school year. This is according to statistics from the Ministry of Education. According to the statistics, the proportion of canceled lessons to the total number of lessons was 9.2 percent. The school authorities divide this into scheduled and unscheduled absences.
In the case of scheduled absences, the timetable cannot be adhered to because there are too few teachers in the first place or classrooms are lacking. Unscheduled absences are caused by teacher illness, further education and training, accidents, strikes, bomb threats or construction work.
