COLD SPRING HARBOR HIGH SCHOOL

• In 2022-23, 95% or more of the 144 students in its four-year cohort graduated with a regular diploma within four years: ED publishes a range, not a figure, to protect students’ privacy.
• In 2021-22, 95% or more of the 135 students in its four-year cohort graduated with a regular diploma within four years: ED publishes a range, not a figure, to protect students’ privacy.

• A public high school for grades 7 to 12.
• Open in NCES’s 2025-26 directory, which is still preliminary.
• Students were enrolled in 2023-24, as the CRDC records it, in Advanced Placement courses (35 courses offered); none in a gifted and talented program or a dual enrollment or dual credit program.
• In 2024-25, 3% of students were eligible for free or reduced-price lunch, 23 of the 719 enrolled on October 1: 23 for free lunch and 0 for reduced-price.
• Around the school, a family with children aged 5 to 17 has an income of about 750% of the federal poverty threshold for its size (100% is at the threshold), by NCES’s 2021-22 estimate from the Census Bureau’s American Community Survey of 2018-2022; its standard error is 94 points.
• That describes the school’s neighbourhood, which NCES says may differ from the neighbourhoods its students live in.

What the school reported to the Office for Civil Rights for 2023-24. These are the school’s own counts, not findings.

• Among the 12 nearest public high schools in New York, within 6.8 miles, the middle value for chronic absence in 2022-23 was 15.8%; this one had 6.8%.
• Students per teacher in 2024-25, by NCES’s counts: 9.8 here; the middle value among them was 10.8.

• Run by COLD SPRING HARBOR CENTRAL SCHOOL DISTRICT, its local education agency in NCES’s directory.
• District spending, fiscal year 2024: COLD SPRING HARBOR CENTRAL SCHOOL DISTRICT spent $54,125 per student, by the Census Bureau’s count of the district’s spending and its 1,533 students, of which $26,701 went on instruction and $26,721 on support services such as administration, buildings and transport.
• That is the district’s figure across all its schools, not this school’s own: its day-to-day spending on salaries, benefits, services and supplies, not on construction, equipment, debt or payments to other school systems.

• Federal school data don’t record findings against a school: the counts here are what the school reported, and the Office for Civil Rights’ own investigations aren’t included.

• Federal school data arrive one to three years after the school year they describe, so each figure here carries its own year.
• The Civil Rights Data Collection is gathered every two years and published about two years later: its 2023-24 figures came out in August 2026.
• To protect students’ privacy, the Office for Civil Rights adds or takes away one at random from counts of students, and ED does the same for chronic absence counts of four or fewer, so a small count may be one off.
• Where the public file shows code −10, “Suppressed in compliance with Executive Order” 14168, figures are withheld: students reported as nonbinary, and harassment allegations based on gender identity, are left out of the counts here.
• The 2021-22 collection didn’t include teacher experience, so there’s no earlier figure to compare it with.
• ED publishes each school’s test results in reading and language arts and in mathematics, but they aren’t loaded here yet.
• ED publishes most schools’ results as ranges, wider for smaller schools, to protect students’ privacy: each is shown as ED publishes it, never as a single figure.
• The CRDC’s 2023-24 public file records Advanced Placement and the International Baccalaureate only where students were enrolled in them, and marks other high schools not applicable: one this page doesn’t name may still be offered.

If you believe something here is wrong, a correction starts with the agency whose record this copies: NCES, U.S. Department of Education or Office for Civil Rights. NCES’s own record is on its school search. If Hearth Record copied something wrongly, it will fix it and log the correction publicly, with its date: how corrections work.
