State maximum group sizes for daycare classrooms, ranked (2026)

Group sizes are the legal maximum the state's licensing rules allow as of the most recent NARA Child Care Licensing Study. A "not regulated" entry means no published statewide ceiling — a daycare in that state can run a classroom of any size as long as it meets the staffing ratio. From a parent perspective, that's strictly worse than a regulated number, so those states sort below all states with a numeric ceiling.

About licensed centers vs. publicly-funded Pre-K: these rankings reflect each state's state-licensed-center rule, which is what most providers in our directory operate under. State-funded Pre-K classrooms typically follow stricter NIEER-aligned group-size caps that do not appear in this licensing-rule table. See the linked state subsidy page for the public Pre-K specifics.

The composite score is the simple mean of infant, toddler, and preschool maximums. We only assign a composite to states that regulate all three bands; partial-regulation states show — in the composite column and sort to the bottom alongside fully-unregulated states. Per-band columns remain populated for partial-regulation states so you can read what they do cover.

About the NAEYC reference numbers (≤8 infants, ≤12 toddlers, ≤20 preschoolers): these are NAEYC's ceilings at the loosest sub-band. NAEYC subdivides further — for younger toddlers (12–28 months) the group-size cap stays at 12 but the ratio tightens to 1:4. The single-band convention here matches what every cross-state licensing study uses; for the full NAEYC sub-band detail see the NAEYC source linked below.

Like ratios, the licensed maximum is a floor on quality, not a ceiling. Individual NAEYC-accredited or QRIS top-tier programs typically run smaller classes than the state minimum requires.
