The maximum length of the instructional day in each high school (averaged over the week, Monday to Friday) shall be 5 hours and 50 minutes. The maximum length of the instructional day in other schools shall be 5 hours and 45 minutes, averaged over the week if necessary. The instructional day is exclusive of the lunch period outlined in Article 5.3 and exclusive of the statutory obligation of teachers to be on duty at least 10 minutes before the morning session begins and at least 5 minutes before the afternoon session begins.
The instructional day may be revised by the Division to meet new Department of Education course credit requirements or to comply with statutory requirements.
Nothing in this article limits a teacher's obligation to discharge their professional responsibilities outside the instructional day.
