This article 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 Google Workspace 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.
Co-teachers can do the same tasks as the primary teacher, except they can't delete a class, remove the primary teacher, or mute another teacher in the class.
To invite teachers using Google Groups, you don't have to be the owner or a member of the group. However, you must be able to view group members and email addresses. If you can't view the list, contact your administrator to change the permissions. Learn more about troubleshooting invitations.
