Depends, If you dont have a good student to instructor ratio. We try to have 1 assistant intructor per every 5 students. Knowing we have 20 kid classes out of the 200+ students we have. There will be atleast 3 assistants on the floor to help control the class, help the class, and help show correct technique. You dont want to have 20 students per 1 instructor. It would be like a school classroom where not every student has time to get helped.
