Disclaimer
What the statistics on Public School Stats are, what they are not, and the limits that apply to every figure on this site.
Republished official statistics
Every figure on this site is republished from publications of the United States federal government — the NCES Common Core of Data and EDFacts and the finance surveys conducted with the Census Bureau — and is attributed to its survey and year on the page where it appears. Republication is a convenience, not a certification: if a figure on this site ever differs from the current official file, the official file governs. NCES releases provisional and revised versions of its files, and figures extracted from an earlier version may differ slightly from later ones.
Not a measure of school quality
The statistics here describe size, staffing, student economics and spending. They do not measure teaching quality, school safety, student growth or family satisfaction, and they must not be presented as school ratings. In particular: a student–teacher ratio is not a class size; a free/reduced-price lunch share is an income-eligibility proxy with known reporting distortions; a diploma count is not a graduation rate; and proficiency percentages, where any source reports them, reflect each state’s own tests and standards and are not comparable across states. Our methodology pages explain each limit in detail.
No professional advice
Content is general information for research and reference. It is not educational, financial, legal or admissions advice, and it is not a substitute for a district’s own published figures or direct confirmation with a school. Enrollment and program details for a specific child should always be confirmed with the school or district, because boundaries, programs and eligibility change between and within school years.
Third parties and advertising
District and school names are used solely to identify the public agencies in the federal statistics. No endorsement by, or affiliation with, any agency, NCES, or the Department of Education is implied. Advertising on this site is served by third-party networks; we do not endorse advertised products or services. Report an error via the contact page and we will trace it to its source row and correct or explain it.
Revisions and coverage notes
Federal files are living documents. NCES designates the 2023–24 universe files used here as version 1a, and later versions can restate individual agencies’ figures; finance files likewise move from provisional to final. A figure quoted from this site should always carry its year, and readers making consequential use of a number should confirm it against the current file at nces.ed.gov. Coverage also has edges a careful reader should know: the CCD counts public schools and agencies, including charter schools authorized as their own agencies; it does not cover private schools (a separate NCES survey does) or homeschooling. Some agencies in the files are administrative units — supervisory unions, regional service agencies, state-operated programs — rather than districts in the everyday sense, and some large systems, New York City most prominently, are recorded as multiple agencies. Where those structures affect a page, the page says so.
Estimates and computed figures
The only computed figures on this site are transparent ratios of published counts — student–teacher ratios, lunch-eligibility shares over reporting schools, per-pupil spending from a single finance record, and shares of state or national totals — each with its formula stated in the methodology pages. We publish no forecasts, no modeled estimates and no interpolated values. If a source cell is empty, suppressed or flagged missing, the corresponding figure on this site is absent or labeled “not reported”; any page that appears to show a precise number for an unreported item should be reported to us as an error.
