Add a co-teacher to a class

This page is for teachers

Note: The previous version of Classroom (without the Classwork page) was deprecated and discontinued on September 4, 2019. For more information, see Classroom classes without the Classwork page.

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.
