Ratios, group sizes, and the better question

A staff-to-child ratio is a legal floor. It is the least supervision a programme may lawfully provide, and it is set by the regulator rather than chosen by the nursery. Marketing frequently presents it as an achievement, which is roughly like a restaurant advertising that it refrigerates its food.

That does not make it unimportant. It matters enormously — it is the difference between a baby being held and a baby being managed. It is just that knowing the number is the beginning of the question rather than the end of it.

The numbers that govern a Queens nursery

Under Article 47, section 47.23: for infants from birth to eleven months, one adult to four children with a maximum group size of eight. For toddlers from twelve to twenty-four months, one to five with a maximum group of ten. For children from two to under three, one to six with a maximum group of twelve. In an emergency, the ratio for children under twelve months tightens to one to three.

Group size is the number people forget, and it may matter more than the ratio. Two adults with ten toddlers and three adults with fifteen toddlers are the same ratio and are not the same room. The cap on group size is what stops a ratio being satisfied inside a hall.

A group of children aged two to five must be in the charge of a qualified group teacher, and staff counted within a ratio must maintain direct line of sight and constant competent supervision of every child at all times. Line of sight is a specific standard rather than a general aspiration.

Why the table you found online is probably the wrong one

Outside the five boroughs, OCFS rules apply: one to four from six weeks to eighteen months in a group of eight, one to five from eighteen to thirty-six months in a group of twelve, and one to seven for three-year-olds in a group of eighteen.

Compare those to the city figures above and the differences are real. The state groups toddlers up to twelve where the city caps them at ten for the twelve-to-twenty-four-month band. Most national comparison articles quote the state numbers, because they are the ones that appear in statewide tables.

So a Queens parent checking a nursery against a table found online may well be checking against looser numbers than the ones the nursery is actually held to. It is worth knowing which document you are holding.

The question worth asking instead

Not what is your ratio — the answer is public and the nursery has no discretion over it. Ask when the ratio is hardest to hold, and listen to whether the answer is specific.

The honest answer, in most centres, is the same three moments: the handover at lunch, the settling period at the start of nap, and the last hour of the day when staff have started to go home and rooms are combined. Those are where a ratio quietly stops holding, and a director who names them unprompted is telling you they have thought about it.

Then ask what happens when somebody calls in sick at seven in the morning. Every centre has that morning. The ones worth choosing have an answer that does not involve hoping.

Be careful with a better number

A centre advertising a ratio better than the legal minimum is advertising a cost. Somebody is paying for the extra adult: either the fee reflects it, or it is being funded from something that will not last, or the number describes a moment rather than a day.

Ask how it is paid for. A straight answer — we charge more, and here is the figure — is entirely respectable. An evasive one is worth noticing.

We run to the ratios and we say so plainly. What we will tell you is that they hold through lunch, through the start of nap and through the last hour, because those are the moments the number is actually about.
