- a course must have a supervisor. He may or may not be a graduate and experienced practitioner of the course he is supervising but he must be a trained course supervisor. He is not expected to teach. He is expected to get the students there, rolls called, checkouts properly done, misunderstoods handled by finding w hat the student doesn't dig and getting the student to dig it. The supervisor who tells students answers is a waste of time and a course destroyer as he enters out-data into the scene even if trained and actually especially if trained in the subject. The supervisor is NOT an "instructor" that's why he's called a "supervisor." (HCO PL 16 Mar 71R)
