Class Scheduling Guidelines

In order to maximize utilization of available space, guidelines apply to all departments/schools.


  1. All courses should be distributed as evenly as possible across these times blocks. No department/school should have more than 8% of their courses during any given time.
  2. No department/school shall be allowed to have more than 65 percent of classes at the peak times .
  3. Departments/schools should try to keep irregularly scheduled courses to a minimum and use conference rooms or alternative space for these classes when possible.

These guidelines are intended to apply to all regular 3 credit hour classes. Other arrangements will have to be made for 4 credit hour, studio, laboratory and similar classes, which do not fit time blocks. For graduate or other classes that meet for 3 or more hours once per week in the evening should be balanced across the days of the week (Monday-Thursday).

Evening and Weekend Time Blocks

Evening Courses can be scheduled 5:30-8:20, or later on M, T, W or R.

Friday and Saturday-only classes are permitted at any time.


Courses that meet 100 minutes or more automatically get a 10-minute break.

Additional 10-minute breaks are added for each 50 minutes of instruction thereafter.
Example: A 3 hour course has 150 instructional minutes and two 10 minute breaks which totals 170 minutes.
