What are the proper counselor-to-staff ratios at camp?

Great question. The answer varies. But we prefer to follow the American Camp Association's (ACA) guidelines. The following information is from the ACA's Camp Parents website:

ACA standards require different ratios for varying ages and special needs. Generally, the ratios at resident camps range from: One staff member for every five campers ages 4 and 5; one staff member for every six campers ages 6 to 8; one staff member for every eight campers ages 9 to 14; and one staff member for every 10 campers ages 15 to 17. At day camps the ratios range from: one staff member for every six campers ages 4 and 5; eight campers ages 6 to 8; one staff member for every 10 campers ages 9 to 14; and one staff member for every 12 campers ages 15 to 17.

Hope this info helps.
