Teaching with Moodle

I wonder could you create version of a non-edting teacher role where these "non-editing teachers" could only see content that was available to their groups. You would have to change other elements of their roles to make sure that had the other necessary teacher privileges. It may be worth a try. I know that we restrict our tutors to only see their own set of students so maybe with a little bit of tweaking you could get what you need
