Adding a grader (or Teaching Assistant) to a class in Pivot Interactives gives that person the ability to view, comment on, and provide scores for student responses for assignments. Graders are added to Classes. If you have more than one class you can add different graders to each class, or assign a grader to multiple classes.
To add a grader, start by going to My Classes. Click the three dots menu at the right of the title bar for the class and select Manage Class & Roster:
Click Add Grader:
Enter the email of the person you'd like to add. An email will be delivered inviting that person to join your class as a grader.
