Verify a school's number
Pick a school, a year, and a metric. This page shows the value we serve and the exact public file, sheet, row, and column where you can check it yourself — plus what the public cross-references do and do not establish. "Verified" here means our value matches the official source file we ingested; it is not a claim that the publisher's number is the truth. How the checks work: data quality.
Professional Performing Arts High School 02M408 HS
School page →1. Reconciliation — Chronic absenteeism rate, 2022-23, All Students
Each group below reslices our NYC DOE data to the exact grade basis a public source reports, so comparisons are like-for-like — and a difference does not mean our value is wrong: row 1 matches the official source file exactly (receipt in section 2).

- school-wide — every grade served, incl. PK/K
Denominator = students in the denominator (10+ enrolled days, 1+ day present). Stored unrounded as 36.69724655; not suppressed.

Counts marked "derived" are value × denominator ÷ 100 — NYC DOE and the Snapshot publish rates, not counts; NYSED counts are published as-is.
Snapshot figures are whole percents with no published numerator or denominator.
Check NYSED's numbers at the source: this school's NYSED report-card page · the exact extract we load (SRC2024_EM_CA_nyc.csv, SRC2024_HS_CA_nyc.csv — find ENTITY_CD 310200011408, YEAR 2023, the All Students row) · primary download (Access database, data.nysed.gov).
A.20 2020-21 → 2022-23 grades 9–12: an unexplained one-sided tail puts many high schools far below NYSED, largely on byte-identical denominators — a publisher-level conflict, not our arithmetic; cause not established (finding A.20, open).
2. Check it yourself — the source receipt
- Download the official end-of-year file: public-school-attendance-results-2019-2025.xlsx (NYCDOE InfoHub; retrieved for validation 2026-06-01, SHA-256 d42143b32bd6…).
- Open the sheet "All Students".
- Find the row where DBN = 02M408, Grade = "All Grades", Year = "2022-23", Category = "All Students".
- Read the column "% Chronically Absent" — it should show 36.69724655(the denominator column is "# Contributing 10+ Total Days and 1+ Pres Day").
Every served school-wide cell for this metric was compared against an independent re-read of this exact file: 10,635 cells, 0 mismatches (4 suppressed cells carry suppression markers in the file; re-read of the file retrieved 2026-06-01). Full report: chronic_absenteeism_rate__validation.md.
3. What the cross-references do and do not establish
NYC School Quality Snapshot— the same agency's public report card, so agreement is a consistency check, not independent confirmation. It displays grade-band rates (K–8 with kindergarten on its elementary/middle page, grades 9–12 on its high-school page), never the school-wide figure. The band basis was established school-by-school across 6,964 report-band pairs from 6,570 school-years: 87% agree within ±1.5 points on the matching band vs only 65% school-wide (finding A.6, largely explained; census).
NYSED — a genuinely different publisher. We reconciled every comparable year × grade band school-by-school against the NYC DOE file: ten of twelve panels agree at the median; the exceptions (2024-25 grades 1–8 and the COVID-era grades-9–12 tail) are chipped on the affected rows above. This year's grades-9–12 panel: median per-school difference -0.60pp across 414 joined schools (47% within ±1pp). Full results: cross-publisher reconciliation · report directory.
