A complete course is in a read-only state. Enrolled students can open the course and access the course content as normal, but are not able to interact in the course, such as participate in discussions or submit assignments. When a course is complete, the instructor can change the course’s availability back to private or open. The Complete Course option isn’t tied to the course’s term.

On the Courses page, instructors can control availability for the courses that they teach. Point to a course card and select the lock icon to change a course’s availability.
You can also change course availability on the Course Content page. When you change the availability of an open course, you can either make the course private or complete the course.
