Licensing sets a maximum children per caregiver by age group. Staff required is children divided by the ratio, rounded up — and a compliance check flags any room that’s short.
The example
10 toddlers, 1:4 ratio.
| A | B | |
|---|---|---|
| 1 | Item | Value |
| 2 | ROUNDUP(10/4) | — |
| 3 | Staff required | → 3 |

How it works
How it works:
- Divide children by the allowed ratio (children per staff for that age).
- ROUNDUP — a partial group still needs a whole caregiver.
- Compare to staff present: compliant if present ≥ required.
- For mixed-age rooms, the strictest (lowest) ratio usually governs.
Ratios are a legal floor, not a target. Licensing sets the maximum children per caregiver by age — infants are strict (often 1:3 or 1:4), older groups looser — and being even one short can mean violations or closure. Always ROUNDUP (9 toddlers at 1:4 needs 3, not 2.25 staff), and in mixed-age rooms apply the youngest child’s ratio. This is illustrative; follow your state’s specific licensing rules.

Round up. A partial group needs a whole caregiver.
Strictest age. Mixed-age rooms use the lowest ratio.
Not legal advice. Follow your state’s licensing ratios.
