After a fair amount of trial and error, I have determined the issue lie not with the actual tacker, but with the tracker PLUGIN. It seems to not honor any permission settings beyond 'user can add a new item'. When this permission is denied, the student sees an error messages stating just that. However, no other permssions seem to carry over, and of special concern, user should not be able to edit his item.
Ideally, this quiz should be in the form of a form, since there is a field for points awarded, and the student should not be able to edit the entire line item in tracker view, but needs to stay only in wiki view, as the checkbox for that option states (which does deny the user the tracker view when selected)
