Assignments: TA can create, edit, duplicate assignments without permissions

After adding a TA to a site, and creating sections with the TA added to 1 section, and giving the TA permission to grade submissions, the TA can actually add, edit and duplicate assignments.

Even though the instructor only gave the TA grade permissions, being added to a section/group automatically seems to add other permissions.

Once the TA is removed from the section/group, then the ability to add an assignment is no longer there.

The TA permissions are a little confusing. If a TA is added to a specific group, then I would expect the TA to have permissions for that group only, and only the permissions set in Assignments. So if the TA is added to section 1 and I only gave the TA permission to grade, (read is on by default), then I wouldn’t expect them to have more permissions just because they were added to a section.

what are your thoughts on this?
