Gradebook

When one of my non editing teachers views the gradebook, they see the grades for all students. This is not a problem for editing teachers since there is a drop down list available at the top of the screen, just below the tabs for viewing grades etc, where they can change the group being viewed. However, non editing teachers have no drop down list and can only see all students.

All my students are assigned to groups and I have the course set up as separate groups. How do I change it so that non editing teachers only can see their own group?

Separate problem - non editing teachers have all the tabs on their gradebook including the change preferences and weighting. I am surprised since I would have thought this was an editing teachers role only. Is there any way to switch the tabs off for the non editing teachers so all they can do is view grades?
