📊 What this ranking measures
Rankings are based on academic achievement — the share of students scoring proficient or above on state reading and math assessments (NCES EDFacts, 2021–22 for most districts), ranked against other districts in the same state — not on spending, district size, or staffing. See full methodology →

Best School Districts in the Lewiston, ID-WA Metro Area (2026)
This metro area crosses state lines, so it is shown as one table per state. Each state rates its districts on its own test, and a 9/10 in one state is not comparable with a 9/10 in another.
Counties are assigned to metropolitan areas using the U.S. Census Bureau's 2023 delineation, and each district is placed in the county of its NCES directory listing. Ratings come from EDFacts 2021–22 (Idaho); SBAC 2024–25 (Washington) and are percentile-ranked within the district's own state. Always confirm your assignment by address.
