The order of the departments in the department picker on your front end is dictated by the sort order for the departments as set in Core. To set a department's sort order:
  1. Navigate to Academics > Scheduling > Requests and Schedules
  2. Select Departments & Courses
  3. Click the Edit icon for the Department
  4. For Sort Order, put in a number
  5. Click Save & Close
The Departments will appear in numerical order, lowest number first.
Note: If some department sort orders are blank and some of 0, the departments with a blank sort order will appear first.
