Well, I already tried that... and ended up with quite a mess. I had a teacher that went in to a test and started changing the point values for certain questions to try to give a student extra credit. This particular teacher chose not to attend any of the training sessions.
I also have teachers who think they know what they are doing when they really don't. All changes to time, date an passwords should be handled through group overrides, but my teachers try to make the changes at the edit settings level. I have restricted the access to group overrides but they are still able to make changes at the edit settings level.
Is there a way to make what is set in group override - override whatever is set at the edit settings level?
