Invite teachers to a class

This page is for teachers. Students go here.

You can invite co-teachers to join your class to help coordinate class activities. If you use Google Groups, you can also invite a group of co-teachers at the same time.

Invite co-teachers or groups of co-teachers

Note: To invite teachers using Google Groups, you don't have to be the owner of the group, but you do have to be a member. Usually, as a member of the group, you can view the list of members. If you can't view the list, contact the group owner to change the permissions. Learn more about Troubleshooting Invitations.

  • The primary teacher can't unenroll or be removed from a class.
  • Teachers can't be muted in a class.
