Book bags and backpacks must be kept in lockers. They may be used to transport books, etc., to and from school. But once the student arrives at school, the bag will be stored in the locker throughout the day. No backpacks are allowed in the classrooms during the day, ‘including seventh period’. Any bag or backpack used by a student must be able to fit in to the locker allowing the locker door to close without damages. Any bag or backpack that is too large to facilitate this may not be brought to school.
