To see which users (if any) are assigned to a given role, follow this procedure.
Log in as admin or as a course
instructor and click the tab.
Navigate to the learning context whose enrollment you want to check. Most often this will be a section. However, if you want to see which users are Course Instructors, navigate to the course level.
Click the
tab. This
brings up a page showing all the roles at that level,
and the number of users who have each role.
To see a list of the users enrolled for a particular role, click on the name of the role.
