The findings, in plain English
New York has 1,842 high schools. 1,395 are public and 447 are private. The 1,389 public high schools that report enrollment hold 775,863 students in grades 9 through 12 between them. The private count is a floor, because the federal private school survey is voluntary and a school can skip it.
Brooklyn Technical High School is the largest public high school in New York. It enrolls 5,848 students in grades 9 through 12 in Brooklyn. The 15th largest school on the table, William Floyd High School in Mastic Beach, enrolls 3,052. None of the 15 largest are charter schools.
The largest private high school in New York is St Francis Prep. It enrolls 2,420 students in Fresh Meadows. That is smaller than every public school on the table above. Private schools report total enrollment to the federal survey, so a school that also teaches younger grades counts those students too. Only schools whose lowest grade is 9 are listed here, so each one is a high school.

NCES Private School Universe Survey 2021-22, respondents only. Total enrollment, not a grades 9-12 count.
What these counts cover
A high school here is a school that serves grade 12. Virtual schools are left out, because a school with no building is not comparable to one with a campus. Public counts come from the federal Common Core of Data, which every public district reports to. Private counts come from the federal Private School Universe Survey.
Enrollment for public schools is the number of students in grades 9 through 12, so a school that also teaches middle school grades is not inflated by them. A school that reports no enrollment figure is counted in the state total but cannot be ranked, which is why the number of schools with an enrollment figure is smaller than the public count.
Private high schools in New York
The private table below shows the largest private high schools whose lowest grade is 9. The survey is voluntary, so treat these as the largest among the schools that answered, not a complete ranking. A private school that declines the survey does not appear at all.
Private enrollment is a total, not a grades 9 through 12 count, because the survey does not break it out the same way. Limiting the list to schools that start at grade 9 keeps the figures comparable to each other.
What a family should do with this
Size is a starting point, not a verdict. A large school usually offers more courses, more sports and more clubs, and a small school usually gives a student more contact with the adults who write recommendation letters. Both shapes send students to good colleges.
The more useful question is where a school's own graduates actually go. Our page for each New York high school carries that school's figures and, where the school publishes one, its own numbered list of the colleges its graduates chose. Start from the school page rather than from the size of the building.
