Senior Master
Or if you have various classes that people sometimes mix and match. At my school, you're mostly separated into kid or adult classes by belt rank (adult beginner+intermediate or advanced, vs. kids beginner, intermediate, and then one class per belt...he's got about 8x the kids as adults), but then there's family classes and all kid or all adult classes for makeup, plus a few others. When you get into a family class or all kid/adult class and you don't know the other people...yeah, it helps.
All you can hope for by that point is that maybe you have a couple "senior students" who could help you run things.
