In this series: New York 2025-26 Enrollment.

A year ago, New York's enrollment report did something it hadn't done in 14 years: it went up. After 13 consecutive years of decline, public school enrollment rose by 5,669 students in 2024, driven almost entirely by migrant families arriving in New York City. Superintendents cited the turnaround. Budget officers adjusted their projections. For one year, the trajectory appeared to reverse.

Then the New York State Education Department updated its enrollment data, and the floor fell out: 2,447,074 students statewide in 2025-26, down 37,176 from the prior year. That is the largest single-year decline outside the pandemic since 2012, it erased the prior year's gain more than six times over, and it pushed the state to within striking distance of 395,000 students lost since 2005. Whatever floor people thought they saw last year was not a floor.

What the numbers open up

The enrollment data covers more than 1,000 districts and 4,700 schools, from Long Island suburbs to Adirondack villages to the 32 geographic districts of New York City. Over the coming weeks, The NYEdTribune will unpack it in a series of data-driven articles. Here is what jumps out first.

One in six NYC students now attends a charter school. Traditional public schools lost 40,802 students in 2026 while charters gained 3,626. Over the full data window, charters added 172,000 students while the traditional sector lost 567,000. The two systems are on diverging trajectories that accelerated through and after COVID.

475 districts hit all-time enrollment lows in 2026. That is 45% of every district in the state. The list includes all five of New York's largest districts — NYC, Buffalo, Rochester, Syracuse, and Yonkers — and stretches from the Bronx to the North Country. Only 14% of districts have recovered from their COVID losses.

Kindergarten hit its lowest level in 22 years. The state enrolled 10,372 fewer kindergartners in 2026 than in 2005, a 5.9% decline to 164,649. At the same time, pre-K enrollment has surged 26% since 2012. More children are entering the system earlier, but fewer are showing up for kindergarten.

By the numbers: 2,447,074 students statewide in 2025-26 — down 37,176 from the prior year, a 1.5% decline and the largest single-year loss outside the pandemic since 2012.

The threads we are following

Nineteen districts haven't grown in 14 years. Rochester, six Long Island suburbs, and a dozen others have posted consecutive annual declines since 2012 — the longest streaks in the dataset. Together, they have lost 43,362 students, a 31.6% combined contraction.

District 75 grew 42% while everything else shrank. New York City's specialized district for students with severe disabilities added 9,614 students since 2005, even as the rest of the city lost 164,000. The growth raises questions about identification practices, program capacity, and funding allocation.

The 9th-grade bottleneck unclogged itself. In 2005, only 71 students reached 12th grade for every 100 who entered 9th. By 2026, that survival rate had climbed to 92 per 100, a 30% improvement that eliminated the retention bulge and added thousands of seniors to the pipeline.

What comes next

This is the first in a series of articles examining what the 2025-26 enrollment data reveals about New York's public schools. New articles publish weekly on Thursdays.

The enrollment figures come from the NYSED IRS Public School Enrollment archive. The data covers headcount enrollment for public school districts and schools statewide.
