Doors open at 8:35 A.M. Classes start at 8:40 A.M. Students are marked late at 8:41 A.M., and must report to the attendance clerk and receive a pass to be admitted to class. A note from a doctor or dentist is the only excuse for lateness that will be accepted. Please note that all lateness minutes are cumulative, once a student reaches 390 minutes the process for illegal absences will begin.
