On 8/19, last year's (2020-21) Skyward Rostered Courses in Canvas will be archived. This does not delete the course. You still have access to it as a teacher.
How to access your archived Skyward rostered courses - also called past enrollments - in Canvas:
1. From your dashboard, select the grey Courses button in Global Navigation.
2. From the pop-up menu, select "All Courses."
3. Scroll to the bottom - you will see "Past Enrollments" at the very bottom of the page.
