Districts

Stanford's SEDA puts every US district's grade 3–8 test results on one scale, in grade levels above or below the 2019 national average, so districts can be compared even across states. Select a district to filter the tables below.

Feeder chains

Each neighborhood elementary school feeds one middle school and one high school, so a home's address sets a child's whole path from kindergarten to graduation. Some elementary areas split between two middle or high schools; those show up as separate chains. Where a district's attendance-area maps are included, the chains come from those maps, with the number of single-family homes in the estimator's areas that follow each one; look up an address in the Home Value Estimator to see its schools.

How to read these numbers

Data sources. School results: OSPI Washington State Report Card, via the WASchoolLens per-district files, which also give each district's feeder chains. District scores: Stanford Education Opportunity Project (SEDA 2025.1) district reports. Each home's district: the King County levy rate book.

Disclaimer. Test results describe a school's students as much as its teaching, and they move from year to year. Attendance boundaries change; confirm a specific address with the district before buying for a particular school.
