Academic quality

ELA = English Language Arts (reading and writing). Math and Science are self-explanatory.
NY State tests ELA and Math every year in grades 3-8, and Science once, in grade 8 -- a school's numbers below only reflect whichever of those grades it actually serves (no social studies/history state test exists at this level).
"Avg. rating" is DOE's average student score on a 1.0-4.5 scale (higher is better) -- shown here as "value / 4.5" alongside the citywide average for the same metric as a benchmark for what's typical.

"% proficient" is the share of students scoring Level 3 or 4 on the state test. Citywide comparisons are the average across schools of the same type. Grades and groups with very few tested students are flagged since a handful of kids can swing the percentage a lot; groups too small to report are omitted by DOE for student privacy -- that's also why Science, tested only once, shows up far less often than ELA/Math.Source: NYC Open Data: School Quality Reports Data (2023-24 school year)

Economic Need Index is DOE's estimate of the share of students facing economic hardship, based on eligibility for public assistance, temporary housing status, and household income relative to the poverty line. Some very high values are reported by DOE only as "Above 95%" for student privacy and are shown here as 95%.Source: NYC Open Data: Demographic Snapshot (2021-22 school year)

1. Open to New York City residents

~23% admitted

There were about 260 applicants in this group and about 60 received offers last year.This group's offers alone accounted for ~100% of the program's seats -- not the same as this group's own admit rate above, since offers can exceed seats (not everyone who gets one enrolls).

Estimates derived from NYC DOE's own wording, which rounds and fuzzes small numbers for privacy. Each group's applicant count is independent of the others -- schools are usually oversubscribed, so applicant counts across groups often add up to more than the total seats. That's expected, not an error.Source: NYC DOE MySchools Admissions Data (2025-26 admissions cycle)
