Instructors may reschedule classes only in exceptional circumstances. Such changes, including evening tests, must have the written approval of the appropriate Department Chair and the Provost. In making such changes, instructors must consider the rights of the individual. If such a change is inconvenient to even one student, the right of that student to attend class at the regularly scheduled time must outweigh the desires of the rest of the class. Classes will not be rescheduled or omitted on the two days immediately preceding or following vacations.
