macOS Sequoia (15.5..0) and permissions

[Bob Sneidar]

Get Info by right-clicking on the filder. You can set the permission for that folder under Sharing and Permissions. But there may be some other issues involved with enhanced security features.

They may not even have access to the same computer the next time they use the lab. Of course, I could assume all lab computers are configured the same. However, the student is udner a deadline (like many student) and probably does not have time to troubleshoot this further as saving to a different location worked.
