Staff-to-Child Ratios by State: The Complete 2026 Comparison

Staff-to-child ratios are the single most important compliance metric for licensed daycare centers. Getting them wrong — even for a few minutes during a staff break — is a high-severity violation in every state.

This guide compares ratio requirements across all 50 states so you can see exactly where your state falls.

Ratios for Texas, Pennsylvania, South Carolina, and Florida were checked against each state's rule text in September 2026 and carry a Verified stamp on their state pages. Figures for other states are summarized from published sources and have not yet been checked — treat them as a starting point and confirm on the state page, which links the official source.

Infant Ratios (0-12 months)

Infant ratios are the strictest across all states. The range goes from 1:3 (the most protective) to 1:6 (the least).

Strictest states (1:3):

• Hawaii: 1:3
• Maryland: 1:3
• Massachusetts: 1:3
• Kansas: 1:3

Most common (1:4): California, Connecticut, Florida, Illinois, Indiana, Maine, Michigan, Minnesota, Montana, Nevada, New Hampshire, New York, North Dakota, Oklahoma, Oregon, Pennsylvania, Rhode Island, Tennessee, Texas, Utah, Vermont, Washington D.C., West Virginia, Wisconsin, Wyoming

Texas splits the band: 1:4 for 0–11 months and 1:5 for 12–17 months (26 TAC §746.1601, verified).

Least strict (1:5 or 1:6):

• Alaska: 1:5
• Alabama: 1:5
• Arizona: 1:5
• Georgia: 1:6
• Kentucky: 1:5
• Louisiana: 1:5
• Mississippi: 1:5
• New Mexico: 1:6
• North Carolina: 1:5
• Ohio: 1:5
• South Carolina: 1:5 (verified, 114-504.B)
• South Dakota: 1:5

Toddler Ratios (12-24 months)

Strictest (1:3 to 1:4):

• Maryland: 1:3
• Massachusetts: 1:4
• Michigan: 1:4 (through 30 months)

Most common (1:5 to 1:7): Most states fall in the 1:5 to 1:7 range for toddlers.

Least strict (1:8 to 1:9):

• Georgia: 1:8 (walking toddlers)
• Mississippi: 1:9 (1-year-olds)
• Texas: 1:9 (18-23 months)

Preschool Ratios (3-5 years)

This is where states diverge the most:

Strictest (1:7 to 1:10):

• New York: 1:7 for 3-year-olds, 1:8 for 4-year-olds
• Connecticut: 1:10
• Massachusetts: 1:10

Most common (1:10 to 1:15): California, Colorado, Illinois, Indiana, Minnesota, Oregon, Pennsylvania, Utah, Wisconsin

Least strict (1:18 to 1:20):

• Alabama: 1:18 (4 years to school age)
• Arizona: 1:20 (5-year-olds)
• Florida: 1:20 (4-year-olds)
• Georgia: 1:18 (4-year-olds), 1:20 (5-year-olds)
• North Carolina: 1:20 (4-5-year-olds)

What About Group Sizes?

Ratios only tell part of the story. Maximum group sizes matter too. A 1:10 ratio with a max group of 20 means you can have 20 preschoolers with 2 teachers. But a 1:10 ratio with no group size limit means a room of 40 preschoolers with 4 teachers is technically legal.

States that set no statewide group-size cap (verified against the rule text): South Carolina (114-504), Florida (s. 402.305(4)).

States that do (verified): Texas — caps by age band from 10 (infants under 12 months) to 35 (four years and up) under 26 TAC §746.1609; Pennsylvania — caps at twice the ratio in every band under 55 Pa. Code §3270.51.

Mixed Age Groups

When children of different ages are in the same room, most states require you to use the ratio for the youngest child in the group. This is critical — it means adding one infant to a preschool room drops your allowed ratio from something like 1:10 to 1:4.

Exceptions:

• Texas uses a "specified age" formula based on the age of more than half the children in the group (26 TAC §746.1603)
• Utah allows up to three 18-23 month olds in a 2-year-old room without dropping to the infant ratio
• Nevada uses an "averaging" method based on the average age of all children in the room

Why This Matters for Your Center

Ratio violations are classified as high-severity in virtually every state. They're the kind of violation that can trigger immediate enforcement action, additional inspections, and in repeat cases, license suspension.

The most common cause isn't intentional understaffing — it's coverage gaps. A teacher goes on break, calls in sick, or steps out of the room, and suddenly the ratio is wrong. Tracking ratios in real-time, having backup coverage plans, and documenting everything is essential.
