Google Classroom Sync was added to the Classroom Management dashboard to allow Google Workspace Teachers to Sync classes without having to ask an Admin to do so from the Admin dashboard.
#Note: This option is not available for non-GWS teachers.
How to Sync Classes
On the Teacher dashboard, you can sync classes by selecting the Google Sync button on the top right of your dashboard.
This will sync all the relevant Google Classroom information such as your Class list, Students assigned to your class, and any additional teachers.
Once the sync is initialized, a pop-up will inform you of the information being imported.
Once completed you should see your dashboard populate with your Google classes.
#Note: if your classes are not visible on the dashboard click on the refresh button.
If your classes are already displaying on the dashboard, if you do another sync it will display that they have been updated.
Congratulations on syncing with Google Sync on your teacher dashboard.
