Pennsylvania Daycare Staff-to-Child Ratios (2025)
Required staff-to-child ratios and group size limits for Pennsylvania child care centers, group child care homes, and family child care homes under 55 Pa. Code.
Pennsylvania Ratio Requirements Overview
Pennsylvania child care ratios are established under 55 Pa. Code and enforced by the PA Department of Human Services (DHS) Bureau of Certification Services. Requirements vary by license type: Child Care Centers (Chapter 3270), Group Child Care Homes (Chapter 3280), and Family Child Care Homes (Chapter 3290). Ratios apply whenever children are in care — including nap time — and must be maintained with qualified staff who meet the applicable background clearance and training requirements.
All ratios below reflect DHS regulations in effect as of 2025. Always confirm current standards with your regional Bureau of Certification Services office, as DHS periodically updates ratio and group size requirements.
Child Care Center Ratios (55 Pa. Code Chapter 3270)
Applies to facilities serving 7 or more children.
| Age Group | Staff-to-Child Ratio | Max Group Size |
|---|---|---|
| Infants (6 weeks – 12 months) | 1:4 | Max 8 children |
| Young Toddlers (12 – 24 months) | 1:5 | Max 10 children |
| Older Toddlers (24 – 36 months) | 1:6 | Max 12 children |
| Preschool (3 – 5 years) | 1:10 | Max 20 children |
| School-Age (6 – 15 years) | 1:12 | Max 24 children |
Source: 55 Pa. Code § 3270.51–§ 3270.54. Maximum group size limits apply in addition to ratios.
Home-Based Program Capacity Rules
Group Child Care Home (Chapter 3280)
For providers caring for 4–6 unrelated children in the home.
- Licensed capacity: 4 to 6 unrelated children
- Provider's own children under age 13 (present during care) count toward total
- When 5+ children under age 6 are present: a second qualified adult caregiver is required (§ 3280.51)
- Total children in home (related + unrelated) subject to DHS capacity limits
- Overnight care: separate written authorization and fire safety plan required
Family Child Care Home (Chapter 3290)
For providers caring for 1–3 unrelated children in the home.
- Licensed capacity: 1 to 3 unrelated children
- Provider's own children under age 13 (present during care) count toward total
- If 3+ children under age 2 are present (including provider's own): only 1 unrelated child under 2 is allowed
- Provider must be in the home at all times — no leaving children with a substitute without prior DHS approval
- Approved substitute must also hold all three background clearances
Mixed-Age Classroom Ratio Rule
When children of two or more age groups share a classroom, Pennsylvania requires applying the ratio of the youngest age group present to the entire room.
Example:
A room has 2 infants (1:4 ratio) and 8 older toddlers (1:6 ratio) — 10 children total.
- • Applying toddler ratio (1:6): 10 ÷ 6 = 2 staff needed
- • But infants are present — apply infant ratio (1:4): 10 ÷ 4 = 3 staff required
Result: 3 staff are required, not 2 — because the youngest child's ratio governs the room.
Planning tip: Separating age groups into distinct rooms whenever possible avoids the ratio escalation cost of mixed-age groupings.

Can a Director Count in the Ratio?
Under 55 Pa. Code, a director may be counted in the ratio only if they are directly supervising children and not performing administrative duties at that moment. This creates a practical challenge: any time the director is answering phones, completing paperwork, conducting parent meetings, or engaged in administrative tasks, they cannot be counted.
Best practice: Plan staffing without counting the director in your regular ratio coverage. Schedule adequate teaching staff to meet ratios independently, and treat the director's time on the floor as a buffer — not a structural coverage position.
Common Ratio Compliance Violations
Counting a substitute who has not received DHS clearance approval: Only pre-approved substitutes with all three clearances may be counted in ratio.
Failing to adjust for the youngest child when mixing ages: A single infant in a toddler room requires the center to staff at the infant ratio for all children in that room.
Nap time reduction: Pennsylvania does not permit reduced ratios during rest time. Staff must remain at required ratios throughout nap periods.
Exceeding licensed capacity in home-based settings: Accepting even one extra child beyond your licensed capacity (including your own children under 13) is a citation-level violation.
Using uncleared household members as caregivers: In home-based settings, any adult who helps care for children must hold all three PA clearances — including other household members.
