Looking for a template that allows multiple login accounts

This will be for a teacher who would like their students the ability to log into their accounts to view scores, assignments, etc. There needs to be a way for the teacher to have admin login privileges (view all, make edits, etc). I’m not too particular about what CMS, or platform.
Is there a product on the Envato site for something like this? Thanks in advance.

All WordPress websites could have this ability by being extended with use of plugins or custom development.

I cannot suggest any themes specifically, but do know there is a teachers / educators category with themes:

You’ll need to review the available themes in that category to see which may suit your specific needs for this.

All the best. Good luck!
