Please allow faculty to limit TA assignment/gradebook access to only those assignments they are grading. Currently my TAs have access to either the entire gradebook, or none of it, but there's no in-between.
I have a course with 10-15 graduate teaching assistants who grade lab reports. I would like to limit them to only those assignments (or even to just their assigned students), and not have the ability to change every grade in the gradebook. After the semester is over I've been unable to revoke access to completed courses, so graduate students will have access to those students' grades indefinitely.
