When assigning a skill in the competency based assignment it would be helpful to only see the skills associated with the class your creating the assignment in. Many classes have the same or similar skill and it's really easy to add the incorrect one. This gives incorrect info when looking at mastery overview or learning progression as a result. If you had the option to view all available skills that would be fine, but if only the skills for the class appeared it would result in less mistakes and less scrolling.
