Summary

Sanislo Elementary School is a small K–5 school in Seattle’s West Seattle area, serving 145 students in a relatively high-need community. It is part of Seattle School District No. 1, which ranks in the 81st percentile statewide, while Sanislo ranks in the 30th percentile among Washington elementary schools. The school’s two-star rating reflects performance that is below the district average, although its statewide ranking has improved from the 15th percentile in 2020–2021 and 2021–2022.

Sanislo’s recent academic direction is encouraging. In 2025–2026, 48.48% of students were proficient in English language arts, 45.45% in math, and 55% in science. Math and science were slightly above Washington’s statewide averages, while ELA was 4.33 percentage points below the state rate and remains the clearest academic priority. Results have risen substantially since 2022–2023, with gains of 13.11 points in ELA, 13.74 points in math, and 14.09 points in science. Grade-level results point to specific challenges: third-grade ELA was 36% and third-grade math was 28%, while fifth-grade math reached 50% and fifth-grade science was 55%. Fifth-grade ELA and fourth-grade math results were suppressed by the state and are unknown.

Sanislo has one of the most favorable student-teacher ratios nearby, at 10.7 to 1, and reported per-student spending of $30,260. Its 66.9% free/reduced-price lunch rate is higher than at most nearby schools, so comparisons should be viewed in context. Still, West Seattle Elementary School, which serves an even higher-need population, trails Sanislo in all three subjects, while Roxhill Elementary School and Highland Park Elementary School also report lower results. By contrast, Maple Elementary School, Pathfinder K-8 School, Fairmount Park Elementary School, and Gatewood Elementary School perform considerably better. Overall, Sanislo appears to be improving, with sustaining math and science gains and strengthening literacy as the key next steps.
