What’s included, how it’s linked, and the limitations to keep in mind. Updated September 7, 2026.
Oregon Department of Education assessment group reports (English, Math, Science).
Results are aggregated at the school level with participant counts and performance levels.
Achievement percentages and public chart summaries labeled “student-weighted” use only students with valid reported scores, represented by ODE’s Scored Performance Denominator. Participant counts are used for participation and coverage, not as the achievement denominator.
These are the core outcome measures used in charts, maps, and summary tables.
Science differs from English and Math in its tested-grade coverage, available student-group categories,
and source-workbook organization. All three subjects include official ODE All Grades rows.
ODE school media aggregate data adds school-level percentages for students experiencing poverty, students with disabilities, required vaccinations, teacher retention, and experienced teachers.
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 geographic reference for map overlays.
A technical note describes data origins, extraction and linkage steps, known limitations, and the latest source-versus-processed coverage audit findings.
