Ratios and group sizes in Pennsylvania centers
The most children one adult may care for, and the largest group allowed in one room, at each age. From Pennsylvania's licensing rules as compiled in the 2025 national database.
| Child's age | Adults to children | Largest group |
|---|---|---|
| 6 weeks | 1:41 adult for 4 children | 8 children |
| 11 months | 1:41 adult for 4 children | 8 children |
| 18 months | 1:51 adult for 5 children | 10 children |
| 35 months | 1:61 adult for 6 children | 12 children |
| 3 years | 1:101 adult for 10 children | 20 children |
| 4 years | 1:101 adult for 10 children | 20 children |
| 5 years | 1:101 adult for 10 children | 20 children |
| 6 years | 1:121 adult for 12 children | 24 children |
| 7 years | 1:121 adult for 12 children | 24 children |
| 8 to 9 years | 1:151 adult for 15 children | 30 children |
| 10 years and older | 1:151 adult for 15 children | 30 children |
The national database reads each state's rule at these sample ages; Pennsylvania's own rules give the exact age bands.
In the room
What the ratio means for your child
A ratio is the most children one adult may care for at once. At 1:4, a room of 8 babies, the largest infant group Pennsylvania allows, needs 2 caregivers. At 35 months the ratio is 1:6, so a full group of 12 needs 2 adults.
When a room mixes ages, Pennsylvania sets the ratio by the youngest child. The ratio is a minimum: on your tour, count the adults and children in the room, and ask how the daycare covers breaks and the first and last hours of the day.
When a room mixes ages, Pennsylvania's rules set the ratio by the age of the youngest child.
Home daycares
Rules for home daycares in Pennsylvania
A Pennsylvania family child care home with one provider may care for up to 6 children. A group child care home has more than one adult and may care for up to 12, plus 3 school-age children, with ratios that depend on the ages in the group.
Ask a home daycare how many babies are in the group, whether a second adult is there all day, and who covers when the provider steps away.
- As the national database records them
- Family child care home (one provider): up to 6 children.
- Group child care home (two or more providers): the rule reads (children to adults): “Regulations include a table that provides the GCCH ratio and group sizes for same-age groupings and mixed-age groups.”
Enforcement
How Pennsylvania checks these rules
- Centers: Pennsylvania reported routine inspections once a year, without notice.
- Family child care homes: routine inspections once a year, without notice.
- In the inspection records: rules on supervision and ratios were 7.6% of the rules Pennsylvania inspectors cited since October 2023, and 53% of the daycares visited had one cited.
What Pennsylvania inspectors cite shows the rule areas cited most often.
Inspection schedules are from a 2017 national survey of state licensing agencies.
On the tour
Ask about ratios on a tour
- of the 2,064 Pennsylvania daycare websites we read post a staff-to-child ratio
- 2.3%
- How many adults are in my child's room, and how many children?
- How do staff keep track of every child during outdoor play, nap and pick-up?
- Who may pick up my child, and how do you check?
- Is the ratio the same at the start and end of the day, when fewer staff are in?
