    Rules that can change these numbers

    When two or more age groups are combined, the ratio for the youngest child applies. All age groups may be combined when 12 or fewer children are in the center. Group size limits do not apply during nap time, meals, snacks, outdoor play, field trips, or special occasions.

    Track staff-to-child ratios in Caredence

    Caredence compares the children checked in to each classroom with the staff checked in to that room, using the children-per-staff limit your center sets for the room, and shows an over-ratio warning when there aren't enough staff. It doesn't apply state rules automatically, so use the figures above to choose each room's limit.
