A German public school usually has two different bodies in charge of it. The Schulträger, as a rule the town or district, is responsible for the outer school matters, such as the building, its equipment and its maintenance. The state school authority is responsible for the inner matters, the teaching staff and the curriculum. In Berlin’s district of Treptow-Köpenick, for example, the district office looks after the caretakers and sports ground attendants, while the regional school supervision deals with the teachers. In one building, the teachers answer to one office and the caretaker to another.
