Waitlisted students have access to a Canvas course within 2 hours of being added to the waitlist on Axess. Waitlisted students will be able to see all course content enrolled students can see. Additionally, waitlisted students can submit assignments and participate in Canvas the same way enrolled students can.
If the waitlisted student is removed from Axess, they will be removed from the Canvas site within 2 hours. If the student was manually added to the Canvas site, they will need to be manually removed.
If you happen to need content from the waitlisted student, such as assignment submissions and the student was removed from the course, you can manually add the student back to the course, retrieve the content, and then delete the student from the course again.
