What’s included, how it’s linked, and the limitations to keep in mind. Updated February 22, 2026.
Oregon Department of Education assessment group reports (English, Math, Science). Results are aggregated at the school level with participant counts and performance levels. These are the core outcome measures used in charts, maps, and summary tables. Science has a different structure than English/Math in key ways (tested grade coverage, available student-group categories, and inclusion of an All Grades rollup row).
ODE school media aggregate data adds school-level percentages for students experiencing poverty, students with disabilities, required vaccinations, teacher retention, and experienced teachers. College-going is included as a high-school-focused field with lower coverage outside HS settings.
U.S. Census Bureau American Community Survey (ACS) 5‑year estimates provide tract‑level income and education metrics. These are linked to schools via geocoding.
NCES locale categories support urban/suburban/town/rural comparisons. ODOT and Census geographies provide spatial context for map overlays.
A technical note describes data origins, extraction and linkage steps, known limitations, and the latest source-versus-processed coverage audit findings.
