Common Issues and Limitations in Google Classroom

Teacher Invitation Limits
If you're unable to invite more teachers to your class, it’s likely due to hitting Google Classroom’s limit. A single class can have a maximum of 50 teachers. Attempting to invite more than this number will prevent additional teachers from joining the class.

Teacher Invitation Frequency Limit
Google Classroom also imposes a restriction on the number of teacher invitations you can send within a 24-hour period, with a cap of 500. Exceeding this limit may result in errors or your invitations being flagged as spam. If you find yourself approaching this limit, it’s recommended to wait until the following day to extend more invitations.
