We have a course with 1 Instructor of Record and 25 Assigned Instructors. Each instructor is assigned a group of students and they need permission to see "only" their assigned students, not the entire gradebook. Any help is much appreciated.
Kim, the only way I know how to do this is to have the students broken apart into different "sections" (not groups) in the course. When you do this then when you add the Instructors (manually; not sure about automatically) you get the check box option to "Can interact with users in their section only" and you can select the appropriate section that the Instructor should have access to. This makes it so the Instructors can only see and Interact with the students in their section - this is not only for the gradebook, but for the entire course.
Here are some guides that will help with this -
