Oregon School Assessment

Data & methodology

What’s included, how it’s linked, and the limitations to keep in mind.

Assessment data

Oregon Department of Education assessment group reports (English, Math, Science). Results are aggregated at the school level with participant counts and performance levels.

Socioeconomic context

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.

Locale & geography

NCES locale categories support urban/suburban/town/rural comparisons. ODOT and Census geographies provide spatial context for map overlays.

Interpretation cautions

  • Aggregate relationships are not causal; they summarize associations.
  • Suppressed or missing counts can affect the tails of distributions.
  • Geographic linking uses tracts as proxies; small‑area heterogeneity still exists.
Detailed logs, reports, and notes are maintained alongside the project data for reproducibility.
