Reproducible pulls from Washington OSPI, Data.WA, and Census ACS — joined with per-school access rules and neighborhood child-density estimates — for 920 public schools across 53 districts in King, Snohomish, Kitsap, and Pierce counties. Per-school research dossiers, private schools, and head-to-head competition data are in progress.
Each level reports different metrics. Pick the level your child will attend — once you're in, you can switch between levels and toggle layers from the sidebar.
Grades K-5 (sometimes K-6). The clearest signal here is SBAC ELA + Math grades 3-5, averaged over three years to smooth small-cohort noise.
Grades 6-8. Adds Level 4 advanced achievement, WCAS Science (grade 8), median student growth percentile, and regular attendance.
Grades 9-12. The richest data set: SBAC grade 10, Level 4, WCAS grade 11, attendance, dual credit / AP / Running Start, ninth-grade-on-track, graduation rates, and college enrollment outcomes.
