Select your state and the calculator loads your official staff-to-child ratio requirements. Add each of your classrooms with the age group, number of children, and number of staff.

Mixed-age rooms are common in childcare, and each state handles them differently.

Check your state's specific mixed-age policy on the full ratio guide page linked in the calculator.
