Oklahoma Daycare Ratios: Staff-to-Child Ratios and Group Sizes by Age

There is no single federal daycare ratio: federal CCDF rules set no numeric ratios, and each state must describe its own ratios and group size limits by age in its CCDF Plan.

Oklahoma's numbers live in OAC 340 Appendix GG of Pub. 14-05, Licensing Requirements for Child Care Programs.

The current edition took effect November 1, 2025.

For single-age groups the chart reads: infants 1:4 with a maximum group of 8, 1-year-olds 1:6 (12), 2-year-olds 1:8 (16), 3-year-olds 1:12 (24), 4-year-olds 1:15 (30), and children 5 and older 1:20 (40).

Oklahoma law defines a child care center as a program operating 30 or more hours a week and a part-day program as 15 to 30 hours, and the same ratio chart covers centers, part-day programs and drop-in programs.

The maximum group size caps how many children form one group: 8 infants, 12 one-year-olds, 16 two-year-olds, 24 three-year-olds, 30 four-year-olds and 40 children aged 5 and older.

The cap works alongside the ratio rather than replacing it.

At 1:4 with a cap of 8, an infant group of more than four children needs a second teaching staff member, and eight is the ceiling for one group.

The same logic runs down the chart: 12 one-year-olds at 1:6, 16 two-year-olds at 1:8, 24 three-year-olds at 1:12, 30 four-year-olds at 1:15 and 40 children 5 and older at 1:20 all sit at the two-staff mark.

When one room spans age bands, Oklahoma publishes a separate mixed-age chart in the same appendix.

Its example rows pair a ratio and group size, and the infant and 2-year-old rows add a per-teacher cap on the youngest children: infants and older children 1:8 with a maximum group of 16 and no more than two children under 2 per teacher; 2-year-olds and older 1:12 (24) with no more than four 2-year-olds per teacher; and 3-year-olds and older 1:15 (30).

For rest time, the provision on record covers 3- to 5-year-olds: one teacher may stay in the classroom while other teaching staff remain in the building on the same floor.

Our research records the rest-time provision for 3- to 5-year-olds only, so confirm nap-time coverage for infant and toddler rooms with OKDHS Child Care Services.

Only teaching personnel count in ratios unless a requirement specifically states otherwise.

Oklahoma's teaching personnel are its assistant teachers, teachers and master teachers, and the tiers carry scheduling limits: an assistant teacher must be at least 16, may not oversee a group alone for more than 3 hours a day, and is overseen by a director, master teacher or teacher who supervises no more than two assistants.

The director's slot matters at scale: when four or more teaching staff are needed for ratio, the director must be free of direct care at least 3 hours a day.

Home daycare capacity follows a separate rulebook from the center chart above.

Oklahoma defines a family child care home as a family home caring for 7 or fewer children and a large family child care home as 8 to 12 children.

With one caregiver, the under-2 mix tightens the count: 7 children with no more than 2 under age 2, 6 children with no more than 3 under 2, or 5 children of any age.

Beyond those limits, a second caregiver is required.

Arithmetic on the chart, room by room: an infant room of 8 needs 2 teaching staff at 1:4; 12 one-year-olds need 2 at 1:6; 24 three-year-olds need 2 at 1:12; and 40 children 5 and older need 2 at 1:20.

Those four rooms together put 8 teaching staff on the floor, which is past the rule's four-or-more point: at that staffing level the director must be free of direct care at least 3 hours a day.

Licensed capacity sets the other staffing floor: Oklahoma requires at least one master teacher per 60 children of licensed capacity.

Treat this as an illustration of how the numbers combine, not a staffing plan — a real schedule depends on each room's capacity and age mix, and OKDHS Child Care Services is the confirmation point.

The current rulebook is the November 1, 2025 edition of Pub. 14-05, Licensing Requirements for Child Care Programs.

Oklahoma carried the ratio and group-size table over unchanged from the 2022 edition, so older charts still online carry the same numbers; the November 1, 2025 edition is the one in force.
