Hi @MargaretRobson1
In my experience, this is an administrative setting you would need to follow up at your university. As an example, we allow pre-service teachers access to some courses, however, our IT department needs to make arrangements for the access in the first instance.
Does your university offer any of the courses as Massive Open Online Courses? This might be another alternative so they can enrol with their own log in process and you can review the results - you could perhaps set the MOOC as a pre-requisite to entry and registering for your internal course.
Let me know what you think and how it all goes.
Thanks
Jen
