Methodology & sources
- NCES Common Core of Data (CCD) directory (as of 2018)
- U.S. Dept. of Education EDFacts assessment results (as of 2018)
- Washington accountability framework (per-indicator). Washington publishes per-indicator dashboard ratings instead of a single rollup grade — this projection is a COSMIQ composite over math+ELA proficiency, not an official state rating. Cross-check the state dashboard for the per-indicator view. (as of 2026-05-27)
