Understanding Staff-to-Child Ratios
Each state sets minimum requirements for how many adults must supervise children at each age level. Here's how the calculation works.
Enter Your Numbers
Input how many children you have enrolled in each age group. The calculator uses your state's official ratio requirements.
Calculate Required Staff
For each age group, we divide children by the ratio and round up. Example: 14 preschoolers at 1:10 = 2 staff required (14 ÷ 10 = 1.4, rounded up).
Check Group Sizes
Many states also limit maximum group size per classroom. We'll warn you if you exceed these limits, even with enough staff.
Automate Ratio Monitoring
Bloomily monitors staff-to-child ratios in real-time across all classrooms, alerting you before you go out of compliance.

Frequently Asked Questions
Do ratios need to be maintained at all times?
Yes, in most states ratios must be maintained throughout the day including during meals, rest time, outdoor play, and transitions. Schedule staff shifts to overlap during busy periods.
What happens with mixed-age groups?
Most states require you to use the ratio for the youngest child in a mixed-age group. If you have toddlers and preschoolers together, apply the stricter toddler ratio to all children.
Can volunteers count toward ratios?
Generally, no. Most states require ratio-counted adults to be employees who have completed background checks and required training. Some states allow trained volunteers in specific circumstances.
How accurate is this calculator?
This calculator uses published state requirements, but regulations change. Always verify current requirements with your state licensing agency before making staffing decisions.
