We are having an issue with professors who need to use more than one rubric to rate an assignment. Our goal is to have faculty use a university-wide rubric to rate an assignment using the Learning Mastery gradebook (Outcomes). However, some professors have their own rubric they like to use for grading the work using the Traditional gradebook (numerical grade). The problem seems to be that they believe if they remove their grading rubric to attach the university one, they will lose their previous grades from their Traditional gradebook. We have been unable to replicate this and wondered if anyone else had noticed this as a problem. Any insights here will be greatly appreciated.
