Add a co-teacher to a class

This page is for teachers

You can invite 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.


Your G Suite administrator might only allow teachers and students from your school to join classes. If you want to add a teacher from another school, contact your admin to update your domain's class membership settings.

Invite co-teachers or groups of co-teachers

Note: To invite teachers using Google Groups, you don't have to be the owner or a member of the group, but you must be able to view group members and view email addresses. If you can't view the list, contact your administrator to change the permissions. Learn more about Troubleshooting Invitations.
