About

By default, when a new Google Classroom is created, the Stream is set to 'Students can post and comment' but that can lead to issues if the Classroom is not monitored by the teacher. In our district we prefer to have the Stream set to 'Students can only comment' but there is no way for a Google Admin to change that default. To prevent teachers from needing to go into every Google Classroom that is auto-generated by the Google Admin to change the setting, installing this extension will prevent students from posting announcements to the Stream even if the setting has not been changed by the teacher. This does NOT prevent them from commenting on posts made by the teacher.

Google admins wanting to use this in their domains should force install this extension on student Google accounts with Developer Tools disabled otherwise they could use the Inspect Tool.

Updated December, 2025 to hide the "New Announcement" button in the updated UI.
