Looking to set up a course for a number of institutions.

Each institution needs its own co-ordinator who will need to be able to see who has completed the course and grades for their organisation.

I want each user to give their institution name when they create their login (preferably from a drop-down list of institution names), and this then assigns them to their Institution ‘Group’. OR ideally their email domain name assigns them to a group.

The co-ordinator can then monitor their Group as a Non-Editing Teacher.

There will be central Managers who add Institutions to the drop down (if email domain cannot auto-assign to groups) and add institution email domains to the accepted list to support authentication

Does this sound like the right model? If so, any pointers/ considerations of how to make it work would be greatly appreciated. Thank you.
