Troubleshooting Canvas Issues for Instructors

I can't sync my roster at all.

Especially if you are a teaching assistant (TA), it's possible that the permissions for your role in Canvas currently do not allow you to access student email addresses, which you will need to sync a roster. If you suspect this may be the case, most likely, you will need to ask another instructor or an admin in your course to make some account and/or permission changes. Here's what to ask them:

• Solution 1: Ask an admin to change the permissions for your Canvas role to allow you and anyone in the course with the same role to "view primary email addresses." Your admin should be able to do this on their Permissions page in Canvas. For more information, you can also direct them to the following Canvas article for admins: How do I manage the Permissions page? Once your permissions are changed, an admin or another instructor may need to re-sync the roster in Gradescope.
• Solution 2: Ask an admin or another instructor to change your Canvas role to "instructor" and then have them resync the roster in Gradescope.
• Solution 3: If your role or permissions cannot be changed, ask another instructor to sync the roster or post grades in Gradescope for you.

I can only sync part of my roster.

If some members of your course can’t be synced along with the rest of your roster, most likely, these members do not have an email address associated with their account in Canvas. To fix the issue, either ask the course members or your Canvas admin to add the email addresses to the accounts in Canvas. Then re-sync the roster.

After I unlink a Canvas course from Gradescope, the initially synced roster will remain on the Roster page even after I link a new course.

Please contact help@gradescope.com to have the excess students removed. Alternatively, if there are no assignments within the course, you can delete it and create a new one to link with Gradescope.

I can't post grades from Gradescope to Canvas.

• Solution 1: Re-sync the roster. Click Post Grades to Canvas again.
• Solution 2: Especially if you are a teaching assistant (TA), it's possible that the permissions for your role in Canvas currently do not allow you to access student email addresses, which you will need to sync a roster and to post grades. If you suspect this may be the case, most likely, you will need to ask another instructor or an admin in your course to make some account and/or permission changes. See the first row of the Roster-syncing issues table above for more info.
• Solution 3: Your Canvas course may have concluded/ended. To allow grades to be posted again, check and update the Canvas course setting’s start and end dates (or the term start and end dates) to include the current time.

To use Gradescope in an embedded window within Canvas, select Preferences from Safari’s settings and then ensure Prevent cross-site tracking is unchecked.
