It depends completely on whether it is a public or private school and whether you mean the WHOLE school or individual classrooms. For public school in individual classrooms, I do know that it is the students responsibility to clean the room at the beginning and end of each day. Students are assigned certain tasks and assigned "clean up duty." This happens mostly due to lack of funding for public schools. As for private, they usually do have more funding and can sometimes afford janitorial staff, but even then some schools still assign students "clean up duty."
