How many children per adult a childcare centre may have

Last reviewed: September 3, 2026VerifiedACUDEN

In short

It is the question every parent asks walking into a full classroom, and it has a written answer. Regulation 8860 sets the adult-to-child ratio by age group, and it also caps group size, which is the part almost nobody looks at. For infants from birth to fifteen months the ratio is one adult per five children and the group does not exceed ten. For toddlers, sixteen months to two years eleven months, it is one per eight, with groups up to sixteen. For preschoolers, three to four years eleven months, one per twelve, with groups up to twenty-four. And for extended hours, five and up, one per fifteen, with groups up to thirty. Where half or more of the group are children with special needs the ratios tighten: 1:3, 1:4, 1:8 and 1:10.

What is it?

It is Section 14.13 of Regulation No. 8860, adopted under Act 173-2016, governing care, development and learning centres. The ratio is not a recommendation: it is one of the criteria by which the Department of the Family determines an establishment’s capacity, alongside the type of service, available physical space and the sanitary-facility ratio. The regulation itself says its requirements are minimum criteria and do not limit an operator wishing to implement higher ones.

Who can do it?

It applies to care, development and learning centres licensed by the Department of the Family. Care homes, foster homes, group homes and institutions have their own articles in the same regulation with different requirements, and this table is not theirs. As a parent or guardian you need nothing to invoke the table: it is the standard the establishment must meet to keep its licence.

Step by step

  1. Step 1: The table, as written

    The regulation gives the ratio by age group and adds a second column that gets forgotten: the maximum group size. Infants, birth to fifteen months: 1:5, up to ten children. Toddlers, sixteen months to two years eleven months: 1:8, up to sixteen. Preschoolers, three to four years eleven months: 1:12, up to twenty-four. School-age in extended hours, five and up: 1:15, up to thirty. Both columns apply at once: adding more adults does not help if the group exceeds the cap.

  2. Step 2: Where there are children with special needs

    There is a second table, triggered where enrolment of children with special needs equals fifty per cent or more of the group. There the assistant ratio tightens: infants birth to fifteen months, 1:3 with groups up to nine; toddlers sixteen months to two years eleven months, 1:4 with groups up to twelve; preschoolers three to four years eleven months, 1:8 with groups up to sixteen; and school-age five and up, 1:10 with groups up to twenty.

  3. Step 3: Who counts as an adult

    The regulation says which people count towards the ratio: directors, teachers and teachers’ assistants. And it sets a condition on the director that settles many arguments: a teacher is required where the centre has preschoolers, and if the director meets the teacher requirements they count in that role only where the centre has enrolment of up to twenty preschoolers. In centres with enrolment of twenty-one preschoolers or more an additional teacher is required. That is: in a large centre, the director cannot keep counting as the group’s teacher.

  4. Step 4: The space: twenty-five square feet per child

    The adult ratio is not the only cap. Interior activity areas are divided into infants, toddlers, preschoolers and extended hours, and that space carries a ratio of twenty-five square feet per child for activities. The count expressly excludes bathrooms, corridors, the kitchen, the food store, the staff room and storage areas: you cannot add the corridor to reach the number. For children with special needs the space must be forty square feet per child. Further, children five and up in extended hours are attended in their own specific activity space, separate from the rest of the enrolment, and the premises must be free of architectural barriers.

  5. Step 5: And the bathrooms

    The bathroom-to-children ratio is one per fifteen, separated by gender in the toddler and preschool areas, and one bathroom must meet the requirements for children with disabilities under the ADA. One bathroom will have a washing area with a bathtub or shower. There must be a nappy-changing area for infants, with a washbasin, a table and storage space for materials, and a separate bathroom for staff and other people.

  6. Step 6: How the centre’s capacity is set

    Section 12.5 says the Department determines the establishment’s capacity, and adds a rule worth knowing: if any government agency with legal authority to set capacity determines a different capacity, the more restrictive prevails. The criteria are four: the type of establishment and service, the physical space available for the service, the staff-to-enrolment ratio, and the sanitary-facility-to-children-and-staff ratio. That is why a centre’s capacity is not a number the operator picks.

  7. Step 7: What you do if the room is over the cap

    The table is a licence requirement, so the route is not to argue it at the door. The Department inspects establishments at least once every three months, and inspections or investigations may be carried out at the Department’s own instance, at the request of the children receiving the service or their relatives, or on a complaint or referral of institutional maltreatment. That is the channel. The regulation also obliges the Department to keep a web-accessible registry of decisions on establishments’ licence status, precisely so interested parents and citizens can verify compliance.

Where to do it

It is not a procedure you apply for: it is a standard the centre meets. If you want it verified, an inspection can be requested from the Department of the Family, and the regulation expressly recognises that inspections may be carried out at the request of the children receiving the service or their relatives. The Department also keeps a web registry of licence status.

What to do if something goes wrong

If you counted the children in the room and got more than the table says, look at both columns before complaining: the adult ratio and the group cap apply together, and those who count as adults are directors, teachers and teachers’ assistants. If the centre has twenty-one preschoolers or more, the director can no longer count as the group’s teacher. If half or more of your child’s group are children with special needs, the table that applies is the second, tighter one. If the complaint is about space, the count is twenty-five square feet per child excluding bathrooms, corridors, kitchen, store, staff room and storage. And if you take it further, the channel is a Department inspection, which the regulation lets relatives request. Three caveats: this regulation is scanned with no text layer and we ran optical recognition over it, reprocessing the table page at higher resolution because two cells did not read clearly; we do not describe here the requirements for care homes, foster homes, group homes or institutions, which have their own articles; and we publish no cost or timeframe because this is not a citizen procedure.

Common mistakes

  • Looking only at the adult ratio and forgetting the group-size cap, which applies at the same time.
  • Counting as an adult someone who is not a director, teacher or teacher’s assistant.
  • Letting the director count as the teacher in a centre with twenty-one preschoolers or more.
  • Applying the regular table where half or more of the group are children with special needs.
  • Including corridors, bathrooms, kitchen or storage in the twenty-five square feet per child count.
  • Assuming the operator sets capacity: the Department determines it and the more restrictive criterion prevails.
  • Applying this table to a care or foster home, which have their own articles in the regulation.

Frequently asked questions

One adult per twelve children from three to four years eleven months, with groups up to twenty-four. If enrolment reaches twenty-one preschoolers or more, an additional teacher is required.

Do the ratios change with children with special needs?

Yes, where enrolment of children with special needs equals fifty per cent or more of the group. Then it is 1:3 for infants, 1:4 for toddlers, 1:8 for preschoolers and 1:10 for school-age.

How much space does each child get?

Twenty-five square feet per child for activities, excluding bathrooms, corridors, kitchen, food store, staff room and storage areas. For children with special needs, forty square feet.

What do I do if the centre does not comply?

The regulation allows inspections at the request of the children receiving the service or their relatives. The Department inspects at least once every three months and keeps a web registry of licence status.
