Course Numbers

Assignment of new course numbers

The heads of the academic units proposing courses should request the assignment of new course numbers. Any of the following changes requires the assignment of a new number:

  • New course added
  • Significant change in content of established course
  • Significant change in credits of established course

Changing course numbers

When the number of an existing course is changed, the catalog description must include a note with the former number (“Formerly offered as…”) for two academic years.

Reusing course numbers

Once a course number has been assigned to a course, it may not be reused for another course until the previous course has been formally dropped (not suspended/archived) and inactive for at least eight years. When a number is used, the Registrar’s Office will append an ‘X’ to the end of the course number of the inactive course to indicate that it has been reused.
