Do I need to add course Teachers as People in ReadyGO, in order for them to see the ReadyGO Instructor Tool in their courses?

No! The ReadyGO Instructor Tool - when enabled for a course - will be automatically available to all Teachers in that course.

When the ReadyGO Instructor Tool is enabled for a course, the "ReadyGO Instructor" link will become available in the Canvas course menu for anyone who is enrolled as a Teacher in the Canvas course.

You do NOT need to add Teachers to the People area of ReadyGO to facilitate access to the Instructor Tool.
