A wide swath of Brooklyn, from Downtown Brooklyn to Gerritsen Beach, will have additional 3-K seats in the 2026-2027 school year.

Additional 3-K seats will be available to Brooklyn families this fall, Mayor Zohran Mamdani announced on Tuesday.

The city will add more than 1,000 new seats in 56 ZIP codes, moving New York closer to making 3-K truly universal for the first time, he said. Last week, the mayor said there will be 2-K seats available in school districts 18 and 23, which covers Canarsie, Remsen Village, Brownsville and Ocean Hill.

Now, additional 3-K seats will be available in Districts 13, 14, 15, 20 and 21, covering: 

  • 11201 — DUMBO, Downtown Brooklyn, Cobble Hill, Vinegar Hill
  • 11214 — Bath Beach, Gravesend, Bensonhurst
  • 11217 — Boerum Hill, Park Slope, Prospect Heights
  • 11218 — Kensington, Windsor Terrace, Borough Park
  • 11222 — Greenpoint
  • 11229 — Sheepshead Bay, Homecrest, Madison, Midwood, Gerritsen Beach
  • 11234 — Bergen Beach, Georgetown, Canarsie, Flatlands, Marine Park, Mill Basin
  • 11238 — Prospect Heights, Crown Heights, Clinton Hill

“For too long, families were promised universal 3-K but offered seats miles away — forcing them to pay out of pocket for child care or leave the city,” said Mamdani said. “Today we’re making a new commitment: government can deliver real relief from the affordability crisis. By making 3-K truly universal, we’re building a city where every New Yorker can afford to raise a family.”

Families who have already applied to 3-K do not need to take any action at this time. As new programs are confirmed and added to MySchools, NYC Public Schools will notify families in those communities. Families may update their applications to include newly available programs until April 24.

“Free 3-K is an essential service for New Yorkers, providing young ones with the foundation for success throughout their academic careers,” said Brooklyn Borough President Antonio Reynoso.
