Informational use only — not legal advice. This page reflects CenterWorth's review of Minnesota Department of Children, Youth and Families (DCYF) regulations as of 2026-08-07. Regulations change. Always confirm current requirements directly with Minnesota Department of Children, Youth and Families (DCYF) before making staffing, licensing, or business decisions.
State-mandated minimum staffing ratios for licensed childcare centers in Minnesota, organized by age group with maximum group sizes and official regulatory citations.
State-specific notes:
| Age Group | Min. Staff Ratio | Max Group Size |
|---|---|---|
| Infant | 1:4 | 8 |
| Toddler | 1:7 | 14 |
| Preschooler | 1:10 | 20 |
| School-age child | 1:15 | 30 |
"Min. Staff Ratio" means 1 staff member per N children. Both the ratio and group size limits must be satisfied simultaneously where both apply.
In addition to the standard age-group ratios, Minnesota regulations specify modified or additional staffing requirements for specific situations. These apply only under the conditions described.
Chapter 9503 does not create a general current reduced staff-child ratio during naps; the maximum group-size rule is suspended during naps/rest while staff-to-child ratios remain controlling.
Naps and rest occur in a quiet separated area. A child who has napped or rested quietly for 30 minutes may not be required to remain on sleeping equipment.

Future law permits a doubled staff-child ratio for up to two hours during nap time for groups that do not include an infant, while enough staff remain in the facility to meet ordinary staffing in an emergency.
Future only; do not apply before July 1, 2027.

Conditional rules apply only in the specific circumstances described. Verify applicability to your facility type and program with Minnesota Department of Children, Youth and Families (DCYF).
Minnesota's staffing ratios determine the minimum number of staff members you must have on the floor at any time — which directly sets your labor cost floor. Since payroll typically represents 50–65% of a childcare center's total operating expenses, the ratio requirement for your primary age group is one of the most important numbers in your business model.
For example, if you operate an infant room in Minnesota at 1:4and enroll 12 infants, you need at least 3 staff members on the floor at all times. If you expand to 16 infants, your required staff count increases accordingly — and your payroll jumps before you see any additional tuition revenue.
CenterWorth's staffing cost calculator lets you model your Minnesota center's exact staffing requirement by age group, enrollment level, and hours of operation — so you can see payroll as a percentage of revenue before you commit to a lease or license.

Regulatory Update History
See current review activity
Minnesota’s stored center rule requires one staff member for every four infants, with a maximum group size of eight, under Minnesota Rules 9503.0040.
The stored record pairs the 1:7 toddler ratio with a maximum group of 14 and the 1:10 preschool ratio with a maximum group of 20.
No general current reduced staff-child ratio is identified in Chapter 9503. The maximum group-size rule is suspended during naps and rest, but the staff-child ratio remains controlling.
The stored record identifies July 1, 2027 as the future date. It must not be applied before then, and operators should confirm implementation with Minnesota DCYF.
