Ratings are the state percentile of each district's combined reading + math proficiency, as reported in the U.S. Department of Education's EDFacts collection (2017–18 school year) — the most recent district-level proficiency file we have processed — converted to a 1–10 scale. Directory data (enrollment, schools, spending, contacts, counties) comes from the NCES Common Core of Data 2024–25. District-to-zip mappings were computed by point-in-polygon lookup of Census ZCTA centroids against TIGER/Line school district boundaries.

Most school-rating sites keep their scores proprietary. We think families, researchers, and journalists should be able to check the math — every rating on this site can be reproduced from the public federal data above, and our methodology page explains each step.
