Click on the "edit" link to see the following screen, set "Active" to "No", and save your changes.
Schoolrunner doesn’t truly delete anything (including courses), but it’s possible to deactivate items like this. If the course you are deleting is based off an active course in your SIS, it may become reactivated the next time Schoolrunner syncs with your SIS. Contact your Schoolrunner administrator for more assistance.
