How Childery computes its state rankings

Ratio data is the legal minimum each state's licensing rules allow as of the most recent NARA Child Care Licensing Study (facility-requirement data current through December 31, 2023, with topic updates through December 31, 2025). The licensed minimum is a floor, not a ceiling — individual daycares may staff above it, and NAEYC-accredited or QRIS top-tier programs typically do.

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 (Georgia's Pre-K Program, Virginia's VPI, New York's UPK, Tennessee's VPK, Oklahoma's Reaching for the Stars Pre-K, and similar programs in other states) typically follow stricter NIEER-aligned ratios that do not appear in this licensing-rule table. A state can rank poorly on its licensed-center floor while running a strong public Pre-K program in parallel — see the linked state subsidy page for that side of the picture.

Composite score is the simple arithmetic mean of the three age-band ratios (children-per-teacher). For comparison, the NAEYC composite would be 6.67. States that report an age band as "not regulated" are sorted to the bottom — un-bounded staffing is not a stricter standard.

About the age bucketing: most states publish stricter ratios than what's shown here for 3-year-olds. The "preschool" column shows the loosest licensed ratio in the preschool bucket (typically the 4-year-old ratio). For example, Florida's 1:20 applies to 4-year-olds; 3-year-olds in Florida are 1:15. The bucketing matches the NARA study's convention so this ranking is apples-to-apples across states, but parents shopping for 3-year-old care should verify the state's single-age cutoff on the linked state directory page.

About NAEYC: the headline NAEYC numbers (1:4 infant, 1:6 toddler, 1:10 preschool) reflect NAEYC's loosest permitted ratio at the largest permitted group size. NAEYC actually subdivides further — younger toddlers (12–28 months) are capped at 1:4, and 2.5–4-year-olds are capped at 1:9. The single-band-headline simplification is the same one every cross-state licensing study uses.

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.

Each ratio dimension's gap is computed as 100 × (state minimum N − NAEYC N) ÷ NAEYC N, where "state minimum N" is the children-per-caregiver in a 1:N ratio. A state with a 1:6 infant ratio is at +50% vs. NAEYC's 1:4. A state matching NAEYC's ratio scores 0; a state with a stricter (lower N) ratio scores negative and is treated as 0 for the composite (we don't reward outperforming NAEYC because the standard is a recommendation, not a target).

Group-size dimensions use the same formula with the NAEYC ceiling as the reference. "Not regulated" is treated as a 200% gap — worse than the worst observed regulated value (typically 30+ for preschool group size) — because un-bounded class size is, from a parent perspective, strictly worse than even a permissive published ceiling.

The composite is the simple mean of the ratio gap and group-size gap. A state with missing data on either dimension shows — in the composite column and sorts to the bottom. The methodology is deliberately simple so a journalist can recompute any cell from the per-state ratios and group sizes published on the linked state directory page.

About licensed centers vs. publicly-funded Pre-K: the gap index is computed against each state's licensed-center licensing rule, which is what most providers in our directory operate under. State-funded Pre-K classrooms typically follow stricter NIEER-aligned ratios and group-size caps that would close most of the gap shown here, but those are governed by a separate set of rules and are not counted in this ranking. A state can score a wide gap on its licensed-center floor while running NIEER-quality public Pre-K classrooms in parallel.

About the NAEYC reference numbers: NAEYC actually subdivides toddler and preschool further than the single-band-headline numbers here imply. NAEYC's 1:4 for younger toddlers (12–28 months) and 1:9 for 2.5–4-year-olds are stricter than the 1:6 / 1:10 used as the reference points in this ranking. This ranking uses NAEYC's loosest permitted ratio at the largest permitted group size, which matches the single-band convention every cross-state licensing study uses. The full NAEYC sub-band detail is in the source linked below.

Participation is defined as having at least one Process-quality signal: a state QRIS rating, an NAEYC / NAC / NECPA / NAFCC accreditation, or a federal Head Start CLASS score. A provider needs only one of these to count. The denominator is Childery's ingested count of licensed, displayable (non-suspended) providers from each state's licensing portal as of the most recent ingestion cycle (May 2026).

This ranking is restricted to states that operate a formal QRIS — 39 states qualify per Childery's rating-system inventory. The 12 states without a formal QRIS (Alaska, California, Connecticut, Delaware, Hawaii, Massachusetts, Mississippi, Missouri, Montana, South Dakota, West Virginia, Wyoming) appear on the separate "Quality-signal coverage" ranking, which uses the same metric without the QRIS-state filter.

Reading the ranking: a high coverage % means a state's QRIS is well-adopted by providers. A low % usually means QRIS participation is technically voluntary and most providers haven't opted in — which is a fair criticism of voluntary QRIS design but not a verdict on the state's underlying quality.

Same definition as the QRIS-participation ranking — a provider counts as having a quality signal if it carries at least one of: a state QRIS rating, an NAEYC / NAC / NECPA / NAFCC accreditation, or a federal Head Start CLASS score. The denominator is Childery's licensed-and-displayable count from each state's licensing portal as of the May 2026 ingestion cycle.

The "Has QRIS?" column is purely informational. A high coverage % with QRIS = No (e.g. NAEYC-heavy states) is the most interesting cell to a journalist: it tells you the state's quality story isn't running through its rating program.

Limitation: this counts whether a signal exists, not what it says. A state where most providers have a published rating but most ratings are 1- or 2-stars is technically high coverage but low quality. The per-state methodology page shows the underlying rating distribution.

Tiering: refundable state CDCC ranks first because a refundable credit pays the family even when state tax liability is zero. Non-refundable credits only reduce a family's tax bill and are worthless to a family with no liability. States with no CDCC sort last (the family is limited to the federal credit).

Where states publish a sliding-scale percentage by income (California, Iowa, New Jersey, New York, Ohio), the percentage column shows the published formula text rather than a single number — clipping to a single percentage would mislead. Use the linked subsidy page for the per-state detail.

Two states (Minnesota, Oregon) operate an independent dollar-formula credit rather than a percentage of the federal CDCC. We flag those as "Independent formula" and link to the state subsidy page for the dollar math.

Entry-eligibility figures are pulled from the first column of each state's `incomeLimits` table for family size 4. Most states publish three columns: very-low-income priority (typically 50% FPL), initial-eligibility (varies by state), and ongoing-eligibility (typically 85% SMI under the 2024 federal Final Rule). We use the *initial* column because that's the cutoff a new applicant faces.

Apples-to-apples comparison is only possible within the structured-table cohort. State programs differ on what counts as income (gross vs. net), what household composition counts, and how often the published tables re-index against federal SMI / FPL updates. The right way to interpret a low-ceiling rank is "narrow targeting," not "weak program." New York at $99k for a family of 4 and Mississippi at $54k are technically comparable on the entry threshold, but the program designs around them are quite different.

States without a structured dollar table fall into one of two categories: (1) the program publishes only a qualitative ceiling like '50% SMI' without a dollar conversion (sorts to the bottom with a 'Not structured' tag), or (2) the program uses a benefit cliff or work-requirement design that doesn't have a simple income ceiling. Visit the linked state subsidy page for the full text.

The waitlist status enum is the cleanest cross-state comparator we have because actual wait times are reported on inconsistent cadences (some states publish a queue length quarterly, others only when asked by Reuters or local press). "Closed" means the portal explicitly stops accepting new applications; "multi-year" is used when the state publishes a wait time measured in years; "reopened" is used when a previously closed program has restarted intake but is still working through a backlog.

Several states use a "no typical waitlist" status because their programs serve all priority-group families on demand but ration capacity by priority group rather than by waiting list. Parents in those states are still subject to capacity limits — see the linked state subsidy page for the priority-group rules.

The composite score is computed as (credential weight × 8) + (pre-service hours ÷ 10) + ongoing hours, with credential weights of 0 (unregulated), 1 (high-school diploma), 3 (CDA), 5 (Associate's), and 7 (Bachelor's). The credential multiplier of 8 is chosen so a CDA-required state always outranks a high-school-required state regardless of how many clock-hours of training the HS state piles on. States that don't regulate any of the three dimensions sort to the bottom.

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 programs (Georgia's Pre-K, Virginia's VPI, New York's UPK, Tennessee's VPK, Oklahoma's universal Pre-K, and similar programs in other states) typically require a Bachelor's degree in early childhood education or equivalent for lead teachers — a meaningfully stricter standard than most state licensed-center rules. A state can rank poorly here on its licensed-center floor while requiring BA-credentialed teachers in its public Pre-K classrooms.

Important caveat: clock-hour requirements measure inputs, not learning. A state with a high pre-service requirement isn't automatically a state with well-prepared teachers — the requirement could be satisfied by sitting through a low-rigor video. The most useful signal for a parent shopping a specific provider is the share of staff actually holding national accreditation credentials (NAEYC, NAC, NECPA, NAFCC), which the state minimum does not capture.

A program is classified as "universal" only when its eligibility rule includes no income test AND the program is offered statewide (or near-statewide — Wisconsin's 4K, for example, is district-optional but offered in 97–99% of districts). "Income-targeted" covers any program that applies a means test, regardless of how generous the income ceiling is. "Limited" covers pilots, small-footprint programs, and statutorily-universal-but-still-rolling-out programs where coverage is incomplete. "None" means no state-funded pre-K.

Borderline cases. Two states with no income test in statute (Maine and New York) currently rank as Universal in our data but warrant a coverage caveat: Maine's school-administrative-unit coverage is ~91% with only ~70% of those running a universal model (~64% of 4-year-olds enrolled); New York's UPK is district-optional and ~50 districts offer none (NYC is universal, much of upstate is not — ~70% statewide enrollment). Both states have statutory universal-by-2026-27 or universal-by-2028-29 goals. Alabama is technically universal but capacity-rationed via lottery (~40% of 4yos enrolled). See the linked state subsidy pages for the full caveat per state.

Eligibility text is quoted from the state's most recent program documentation. The ranking does not weight states by 4-year-old enrollment because NIEER enrollment data is one year behind the program rules — a state can be universal-on-paper while its actual enrollment lags. Parents who care about both should read the linked subsidy page where we cite the most recent NIEER coverage figure.
