Students who must use Practice Rooms or labs after regular hours must obtain security passes. A security pass must be requested by the teacher of the course requiring additional hours and obtained through the Department Secretary and approved by the Chairman. The student using a security pass will call Public Safety (x3-6606) and inform them. Public Safety will dispatch an officer who will unlock the room at that time. NOTE: Security passes will not be given for using the Music Library, which is only open when staffed.
