Beginner to intermediate players are usually no more than 10 per coach, we try to keep to an 8:1 student/coach ratio but this depends on the day and time signed for.  Limit 10 adults per coach.  There is always a minimum of two coaches for the adult clinics and typically there is an advanced group and a beginner group, sometimes a third or fourth coach is needed and will be added based on the number of students. The classes are tailored to fit the skill level of the current group.
