Wisconsin Childcare Licensing
Wisconsin Childcare Staff-to-Child Ratios (2026)
Wisconsin sets a maximum staff-to-child ratio for each age band a licensed center serves. The strictest ratio applies to the youngest children: Birth to 18 months must be supervised at no looser than 1:4 (maximum group size 8). Meeting these ratios at all times is a core Wisconsin licensing condition.
