Adult to Child Ratio

Research shows that the quality of child care improves when children are in smaller groups and get more attention and care from adults. So, there are licensing rules that set a maximum number of children for every available adult. Different rules apply to different types of care providers.

Minnesota Rule 9502.0367 governs ratios for licensed family child care homes. A single adult caregiver may care for 10-12 total children under the age of 12 years, including her own.

Minnesota Rule 9503.0040 governs ratios for child care centers. The minimally acceptable staff-to-child ratios and the maximum group size within each age category are:
