Thank you Marcus - this is very helpful!
I have one follow up question. Although the rubrics are associated with a course. . . if a teacher is in their Civics course and selects the option to "include my own forms" when searching for a template, will they be able to access rubrics they created in Geography? When I do a search like this I see rubrics from various courses, but I am not sure if that is because of my level of permissions.
Thanks again!
