A team of school presidents is also elected by the pupils each year, whose main purpose is organizing school parties, sports tournaments and the like for their fellow students. The local town is responsible for the school building and employs the janitorial and secretarial staff. For an average school of 600 – 800 students, there may be two janitors and one secretary. School administration is the responsibility of the teachers, who receive a reduction in their teaching hours if they participate.
