Students served: 41% students eligible for free or reduced-price lunch. Many New York high schools report 95% or more of students proficient, so comparisons among top schools here are less precise and we don’t estimate a “versus similar schools” figure. (Context only; not part of the score.)

The overall Repit Score ranks this blend against every rated school in New York. Schools are compared within their state because each state sets its own tests and proficiency bar. How we rate schools

About Repit School Scores

Parents choosing a school deserve to see what it actually delivers. Since October 2026 the Repit School Score is built mainly on results:

  • Academics (largest share) — the share of students scoring proficient in reading and math on the state test, ranked against schools of the same level in the same state.
  • Graduation (high schools) — the four-year adjusted cohort graduation rate. Only regular diplomas count; GEDs and certificates of attendance do not.
  • Resources (smaller share) — class size, per-pupil funding, school size and type.

Scores compare schools within their own state, because every state writes its own tests and sets its own proficiency bar. Full methodology
