127 public K-12 schools in Seattle from NCES Common Core of Data: enrollment, grade span, demographics, and Civil Rights Data Collection statistics for every active campus.
National city placement
According to NCES CCD 2024-25, Seattle has more public-school enrollment than 99% of the 4,487 US cities in this directory. Seattle is among the largest city school systems in this directory by enrollment, but its campuses are divided among 8 districts. That combination matters: citywide averages blend separate budgets, staffing policies, attendance boundaries, and program rules. For a family comparing schools here, the district column is as important as the city average; two nearby campuses may answer to different boards and draw on different F-33 funding pools.
Seattle's list includes 42 elementary, 15 middle, and 20 high-school campuses, plus 50 combined-grade records. The city average spans every major grade stage, so the ranked table is more informative when read within level than as one interchangeable queue.
Seattle's average Resource Investment Index sits at the 95th percentile, while its teacher-staffing measure sits at the 46th percentile. The 49-point percentile gap is a reminder that the index is not a class-size score: counselors, gifted-program reporting, and attendance also affect it. Compare those components directly when two schools have similar index totals; the same headline score can arise from a different mix of reported resources.
Seattle school enrollment ranges from 3 students (lowest) to 1,770 students (highest), a spread of 1,767 students. That ratio is an extreme outlier spread — among the widest gaps observed anywhere in this dataset. Per-school staffing and program breadth can differ sharply at opposite ends of that enrollment range, so the city average should not be treated as a typical campus.

Each school district has independent budgeting, hiring, and service delivery authority. The fragmentation reflects historical patterns of inter-municipal boundary lines that pre-date modern city growth, students in different parts of the same city can attend different districts with different per-pupil spending, calendars, and graduation requirements. Per-region variation is largest in fragmented systems because each school district sets its own budget, contracts, and priorities without higher-level coordination above the regulatory floor.

student-teacher ratio is the simplest comparative metric but it does not capture the full picture: the ratio counts FTE classroom teachers against total enrollment, push-in specialists, English-language aides, special-education co-teachers, and counselors are not included in most reporting Variation between sub-units within Seattle is typically wider than the Seattle-aggregate figure suggests.

Ranked by the Simpson student-body diversity index (0-100) from NCES race and ethnicity data, where higher means a more evenly mixed student body. It measures mix, not quality.
Puget Sound Skills Center has the highest Resource Investment Index among the Seattle schools in this federal-data comparison at 85/100. The index summarizes reported staffing, counseling, gifted-program, and attendance inputs; it is not an academic rating.

Data from NCES Common Core of Data (CCD) 2024-25 and Civil Rights Data Collection (CRDC) 2021-22. The Resource Investment Index uses reported student-teacher ratio, counselor access, gifted programs, and attendance; it is not an academic rating. Cities must include at least five schools to be listed. This public-data comparison is for informational purposes: verify current enrollment, attendance boundaries, and programs with the school district before acting.
