When we originally set up our courses, each course was set up for separate groups. Our supervisors are added to each course within a specific group. Originally, the supervisors could only see the grades of the other members of their group, and that is the way it should be. However, now when a supervisor goes into the grade book, they see the grades for all the individuals enrolled in that course. I have checked the courses and they are all still set to separate groups. And I have checked the permissions for the supervisor role which is set for "View all groups - prohibit". Why can they now see everything? I don't know what else to check, it seems as though these two things should provide the grade book view I am looking for. Does anyone have any other ideas of things to check or ways to trouble shoot this issue? There are three System Admins for our site and I am not sure which one of us made a small change that seems to have had large repercussions, so I am not sure where to start looking.
