Would it be possible to limit the grades TAs can view while marking; so not only within sections, but from viewing past assignments that a Teacher-level may have graded as well. Thank you for considering!
Thanks for sharing this idea. Before we move it forward for broader consideration, have you already made this request of the local Canvas admin for your organization? Canvas has a standard TA role that local admins can customize based on a particular school's needs, and the Canvas Permissions PDF linked in the admin documentation How do I set permissions for a course-level role i... - Canvas Community suggests that a TA's ability to view grades might be a specific permission they can turn on or off. (It's in the Grades - view all grades section that starts on page 14 of the PDF).
We'll keep this idea in moderating status in the meantime. Thanks again!
