Utah sets child care center staff-to-child ratios and maximum group sizes in Utah Administrative Code R381-100-10, administered by Child Care Licensing (CCL) in the Utah Department of Health and Human Services.
Infants are staffed at 1:4 with a maximum group of 8, two-year-olds at 1:8 with a group of 16, and school-age children at 1:20 with a group of 40.
Ratios can double at nap time only under the conditions the rule sets, and family child care homes follow separate capacity rules under R430-90 and R430-50.

1:4 for both the 0-11 month and 12-17 month bands, with a maximum group size of 8.
1:5 for children 18-23 months, with a maximum group size of 10; 12-17 months stays at 1:4.
1:12, with a maximum group size of 24.
1:15, with a maximum group size of 30.
1:20 for children 5 years and older, with a maximum group size of 40.
Capped per age band in R381-100-10, Table 1, from 8 for infants to 40 for school-age; a center constructed, licensed and continuously operating since January 1, 2004 can be exempted if ratios and square footage are met.
Utah sets center ratios by age band in R381-100-10, Table 1, from 1:4 for infants to 1:20 for children 5 years and older.
Each age band also caps the group, from 8 children to 40; a center constructed, licensed and continuously operating since January 1, 2004 can be exempted from maximum group sizes if ratios and square footage are met.
The ratio may double at nap time only if every child is at least 18 months, all are resting, and the supervising caregiver can reach another caregiver without leaving.
Two caregivers are required whenever the only group on site has more than eight children or more than two infants or toddlers.
A separate rule (R430-90, not R381): one caregiver for up to 8 children and two caregivers for 9-16, with tighter caregiver limits when children under 2 are in care.
| Age group | Staff-to-child ratio | Maximum group size |
|---|---|---|
| 0-11 months | 1:4 | 8 |
| 12-17 months | 1:4 | 8 |
| 18-23 months | 1:5 | 10 |
| 2 years | 1:8 | 16 |
| 3 years | 1:12 | 24 |
| 4 years | 1:15 | 30 |
| 5 years and older | 1:20 | 40 |
Age bands as they appear in Table 1 of R381-100-10; the school-age band is 5 years and older.
Utah center ratios run by age band in Table 1 of R381-100-10, the rule Child Care Licensing (CCL) in the Utah Department of Health and Human Services administers.
The bands are 1:4 for children 0-11 months, 1:4 for 12-17 months, 1:5 for 18-23 months, 1:8 for 2-year-olds, 1:12 for 3-year-olds, 1:15 for 4-year-olds and 1:20 for children 5 years and older.
Each ratio is the fewest caregivers a group can run on, so a full infant group of 8 puts at least 2 caregivers on the floor at 1:4.
The table above gives every band with its maximum group size.
Group size caps how many children one classroom can hold even when staffing is generous, and it is separate from the ratio.
Utah's maximums in Table 1 of R381-100-10 are 8 children for infants (0-11 months and 12-17 months), 10 for 18-23 months, 16 for 2-year-olds, 24 for 3-year-olds, 30 for 4-year-olds and 40 for children 5 years and older.
One exception exists in the rule: a center constructed, licensed and continuously operating since January 1, 2004 can be exempted from maximum group sizes if it meets the ratio and square-footage requirements.
Confirm any group-size question with CCL before you set classroom enrollment.
Nap time and mixed-age rooms change the math.
A Utah center may double the caregiver-to-child ratio during nap only if every child in the group is at least 18 months, all of the children are resting, and the supervising caregiver can reach another caregiver without leaving, so an infant room or any group with a child under 18 months never qualifies.
For mixed-age groups without infants or toddlers, the ratio is set by the oldest child's age group minus one child, and the group size by the oldest child's age group minus two.
Read on a room of 3- and 4-year-olds, that runs the group one child under the 1:15 four-year-old ratio and two children under the 30-child maximum.
โDuring nap time, the provider shall ensure that the caregiver-to-child ratio is doubled only if:โ
For Utah center ratio purposes, a caregiver can be 16 or older, pass an Office of Background Processing check, complete the Office of Licensing's 2ยฝ-hour preservice training before working with children, and complete 20 hours of child care training each year.
Volunteers 16 and older and registered high school or college child care student interns can also count in Utah center ratios.
Staffing floors sit on top of the ratio: two caregivers are required whenever the only group on site has more than eight children, or more than two infants or toddlers.
At least one staff member with current pediatric first aid and CPR must also be present at the facility, on each offsite activity and in each vehicle.
โthere are at least two caregivers present when there is only one group of children on the premises and that group has more than eight children, or more than two infants or toddlers.โ
The center table above does not govern homes: Utah's family child care rules sit in R430-90 (Licensed Family Child Care) and R430-50 (Residential Certificate Child Care).
Residential certificate child care covers eight or fewer qualifying children, or up to ten including the provider's own children, in the provider's home; a Licensed Family Child Care license is required for care of nine or more unrelated children, four or more hours a day, on a regular basis.
A licensed family child care home runs one caregiver for up to 8 children and two caregivers for 9-16; with children under 2 in care, the rule sets one caregiver per three under-2s and no more than two children under 18 months per caregiver.
Any home caring for more than ten children under 13 must be licensed, and a provider who is not required to be certified must care for no more than two children under 3 and register with the Office of Licensing for a background check.
Take a center running one room per age band at full enrollment, as an illustration of how the rule's numbers combine.
An infant room at its maximum group of 8 needs at least 2 caregivers at 1:4, because the ratio covers at most 4 infants per caregiver.
A 2-year-old room of 16 needs at least 2 caregivers at 1:8, and a 4-year-old room at its 30-child maximum needs 2 caregivers at 1:15.
The two-caregiver floor is the rule a single-group center runs into: a center whose only group on site is nine 3-year-olds needs two caregivers even though nine children sit inside the 1:12 ratio, because the rule requires two whenever the only group on site has more than eight children or more than two infants or toddlers.
Nap time changes a room's caregiver count, not its group size: the 24-child 3-year-old room that runs on 2 caregivers at 1:12 may run on 1 during nap only if every child is at least 18 months, all are resting and the supervising caregiver can reach another caregiver without leaving.

One caregiver per 4 infants.
Utah's rule sets the ratio at 1:4 for both the 0-11 month and the 12-17 month band, with a maximum group of 8, so a full infant room runs on at least 2 caregivers.
The two-caregiver floor also applies whenever the only group on site has more than two infants or toddlers.
Only under the conditions the rule sets: every child in the group is at least 18 months, all of the children are resting, and the supervising caregiver can reach another caregiver without leaving.
A group that includes any child under 18 months โ every infant room, for example โ does not qualify, and the regular ratio applies throughout nap time.
It depends on the permit.
Residential certificate child care covers eight or fewer qualifying children, or up to ten including the provider's own children.
At nine or more unrelated children, care falls under a Licensed Family Child Care license, and a licensed home runs one caregiver for up to 8 children and two caregivers for 9-16, with tighter caregiver limits when children under 2 are in care.
Yes.
Utah center caregivers can be 16 or older, pass an Office of Background Processing check, complete the Office of Licensing's 2ยฝ-hour preservice training before working with children, and complete 20 hours of child care training each year.
Volunteers 16 and older and registered high school or college child care student interns can also count in Utah center ratios.
40 children, in the school-age band for children 5 years and older.
Below that, maximum group sizes run 8 for infants (0-11 and 12-17 months), 10 for 18-23 months, 16 for 2-year-olds, 24 for 3-year-olds and 30 for 4-year-olds.
A center constructed, licensed and continuously operating since January 1, 2004 can be exempted from the group-size maximums if it meets the rule's ratio and square-footage requirements.
