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