However it is understandable that many schools would prefer not to have students in a school-provided video conference without the teacher present. That is, schools may not want students to be able to join a Meet before the teacher gets there, or be able to rejoin a Meet after the teacher has left. Thankfully Google has provided an option to manage this.
To help with this I have recorded a short 7-minute video explaining how to do manage this. However, be aware there are some settings that your tech administrators need to adjust before this will work. I have made a separate video just for the tech admins which can be found in my other blog post on "How to Keep Students from Starting or Recording a Meet".
Now assuming that your tech folks have adjusted the settings they need to change, see below for the video on how you as a teacher can keep students from joining a Meet before you, or after you have left the meeting.
NOTE: If you use Google Classroom, Google has just rolled out a new integration that lets you create a unique Meet link for each of your classes, which you and your students can easily access in Classroom, but your students can't join the Meet without you being there. I have created a video and blog post with all of those directions here: "Google Meet is now integrated in Google Classroom"
Tutorial Video (7 minutes)
Here is my quick 7-minute video on how to keep students from joining a Meet before you have joined, or from rejoining a Meet after you have left.
Or if you use Google Classroom, here is my 6-minute video on how you can use the new Google Meet integration in Classroom to generate a Meet link for each of your classes, which students can't join without you:
