Illinois Compass 2g, Who has permission to enroll students or add instructors to course spaces?
Instructors and Course Administrators have full access to enroll or remove any user from the course site, regardless of that user's role (i.e. Instructors can add or remove Instructors, Teaching Assistants, Students, Course Builders, Graders, or Guests). They can also mark any user as "unavailable" for the course. This is encouraged for students, because it does not remove any accumulated grades.
Which Compass 2g roles have permission to enroll Students and other roles into an Illinois Compass course site?
Customers with the Teaching Assistant (TA) role cannot remove an Instructor from a course nor can they change roles or availability of users in the course. They may enroll Students and un-enroll anyone who is not an Instructor.
Also, Instructors CAN'T remove other instructors directly, but there is a workaround. If an Instructor needs to remove another Instructor they can change the user's role to Student, then remove the user from the course.
