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, converted to a 1–10 scale. 90% of districts use the 2021–22 school year (the most recent federal district-level file available); the remaining ~10%, where that file has no matching record, fall back to 2017–18 so a rating is still shown. Each district's row in the CSV and each page's "Show the math" panel states which year was used. 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.
