The NYC 3-K Guide
A clear walk-through of how 3-K works in NYC — calendar, MySchools, after-school, priority rules, and what we wish someone had told us.

We get asked about 3-K constantly — and for good reason. The process is spread across three different city websites, the calendar doesn’t match anyone’s work schedule, and the rules that actually move the needle (priority, ranking, district guarantees) aren’t the ones you read about first. This is the walk-through we wish we’d had as toddler parents, written plainly.
Start with the official sources
Before anything else, get familiar with the three pages NYCDOE actually runs the process on:
- The NYCDOE 3-K enrollment page — eligibility, dates, and how the application opens each year.
- The 2025–26 public school calendar — every closure, recess, and half-day. Read it before you fall in love with a program.
- MySchools— where you create your child’s account, browse the program directory, and submit the application. The map view is cumbersome; the list and search work better.
Do the calendar math first
Once we counted school closures against a typical 11-holiday job, we landed on 90+ days a year — summer, winter and spring recess, chancellor holidays, half-days — when 3-K is closed but the adults in the house still have to work. That gap is the real question behind “which program fits us.” Run the math against your own employer’s calendar before you short-list anything.
Build your own list
Open a Google Sheet and start tracking the programs you’re interested in alongside the things MySchools doesn’t surface consistently:
- Cost of after-school (the 2:30 pm–5 pm gap).
- Cost of early drop-off, if you need it.
- Summer programming — offered, run by whom, separately priced?
- Coverage on the days DOE releases students early.
- Anything else that matters to your family that the listing skips.
A short spreadsheet beats a long browser-tab graveyard every time.
Call programs directly
For everything missing from MySchools, pick up the phone. Most programs run open-houses or private tours and will happily walk you through cost structures, hours, and the gap-day question. Two or three calls usually tell you more than a week of website reading.
What to keep in mind
The rules that actually shape your odds:
- 3-K hours run roughly 8 am to 2:30 pm. Working parents need an after-school plan for the back half of the day — ask each program what it offers and what it costs.
- When you submit doesn’t change your odds. You’re not racing anyone. Don’t rush a half-finished application.
- Programs that already serve 1- and 2-year-olds give those kids priority for 3-K seats. If a program is heavily weighted toward existing toddlers, that affects how many seats are actually open to you.
- Not every district guarantees a 3-K seat for every child. The city guarantees a NYC seat, which means a placement might land you in a different district than the one you applied from. Plan for it.
- Rank in true preference order.The match algorithm can’t be gamed by ranking your “safety” program first. Put your real first choice first.
- You won’t hear back until May. Once an offer arrives, you typically have 1–2 weeks to accept.
Where we come in
Once you have your list, our early education directorylets you compare programs side by side — quality data, neighborhood context, and after-school availability where we have it — so the spreadsheet you keep deadlines in has better information feeding it. The application still happens on MySchools; everything around it gets easier when the information lives in one place.
