Removing a Co-Instructor

Blackboard automatically prevents you from accidentally removing co-instructors, displaying the following error message in red when you attempt to do so: “Cannot remove Instructor users from course. Only System Administrator users can remove Instructor users.”

To request that a user be removed from a course you need to submit an email to Include the following in the email:

  • The user-id you used to log into Blackboard
  • The course-id, e.g., 20153_XXX_###_#####
  • The user-id and name of the user you want to remove, and finally
  • A statement about why you need to remove this user.

Please note that Blackboard’s user data including instructor assignments comes directly from USC’s Student Information System (SIS). If the co-instructor is still assigned to teach the course in SIS, he or she will automatically be re-enrolled in your course within an hour or two. To prevent this from happening, please contact your department’s course scheduling coordinator and request that the coordinator remove the co-instructor in SIS before sending the email to
