About schools in King County

Twenty-seven districts and 468 ranked public schools make King County one of the most educationally diverse regions in the Pacific Northwest — ranging from high-density urban schools in Seattle to suburban campuses in Bellevue and smaller communities in Auburn and Kent. Nearly half of those schools score in the top quartile statewide, a proportion that reflects genuine depth rather than a few outliers carrying the numbers. Cascadia Elementary in Seattle and Nikola Tesla STEM High School in Redmond both sit at the 100th percentile statewide in math and English, representing the county's ceiling — but strong performers appear across multiple districts, giving families real options depending on where they land.
