SmartSite is a little different from MyUCDavis when it comes to adding grades. So here are some tips!
In order to assign TAs/Graders permissions in the gradebook, they first need to be assigned to one or more sections using the “Section Info” tool in SmartSite. Teaching Assistants and Graders can be granted grading privileges in Gradebook 2. By default, participants with the Teaching Assistant role have the ability to view or manipulate grades for the section(s) to which they are assigned in the Section Info tool.
