In German schools, pupils take on named classroom duties, the Klassendienste or Klassenämter. The Tafeldienst makes sure the board is clean before each new lesson. The Ordnungsdienst keeps the room tidy. The duties pass from pupil to pupil in turn. A secondary school in Bremen explains its list this way: Zudem schult die Aufgabe, Verantwortung zuverlässig und sorgfältig wahrnehmen zu können. The task also trains the children to carry responsibility reliably and carefully.
