Hi @BobbieJeanKoen,

What we do is instead of trying to provide a separate rubric is to give teachers the instructions to add the individual account-level outcomes to their course, the insert those outcomes into their own rubrics (deselecting the option to use them for scoring).  This way you can collect outcomes/mastery data but still allow teachers to use their own grading rubrics/criterion.

I hope this info helps!
