All child care centers should adhere to the following: child ratios and group size outlines below for prevention, containment, and mitigation measures.
Age Staff:Child Ratio Group Size
0-18 months (infant) 1:4 10
18-36 months (toddler) 1:6 10
3 years-kindergarten entry 1:10 10
(preschool) & kindergarten entry
0 to school age (mixed age groups) 1:6 10
Follow the group sizes in the chart, unless more restrictive group sizes are required by federal, state or local authorities. The group sizes do not include the teacher. When mixed ages are present and include an infant under 18 months, adherence to the ratio 1:6 must be followed to allow for responsive care giving. If all children being cared for are infants, adherence to the 1:4 ratio must be followed within a group size, with no group no larger than 10.
Family Child Care Homes (FCCH)
Small and large family child care homes serve a total capacity of no more than 14 and group size may not exceed 10 children, unless more restrictive group sizes are required by state, federal or local authorities. (Over ten children will require an additional staff or assistant to maintain group sizes of ten or fewer children).
If there are more than 10 children in care, then the children need to be divided into two groups and kept separate from the other group of children each day, to the greatest extent possible. It is important to keep the same children and teacher or staff with each group and include children from the same family within the same group, whenever possible.
