Show how many students received a certain criteria on a rubric.
Hey William, it sounds like you want something similar to the Learning Mastery Gradebook which allows you to add an outcome to a rubric and then view the level of mastery on that outcome for your students. We have a good guide on that at How do I use the Learning Mastery Gradebook to view outcome results in a course?
If that is not what you're looking for, can you update your feature idea to be more specific with the functionality you're interested in and let me know in the comments below?
Did you get a chance to look at the guide Adam linked to?
