Methodology & sources
- NCES Common Core of Data (CCD) directory
- U.S. Dept. of Education EDFacts assessment results
- California accountability framework (per-indicator). California 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)
