Summit Public School: Sierra

The Summit Public School: Sierra area includes one school, Summit Public School: Sierra, a small public high school serving grades 9–12 in Seattle, Washington. It enrolls 214 students, has a student–teacher ratio of 15.2:1, and reports per-student spending of $20,964. About 38% of students qualify for free or reduced-price lunch. Because there is only one school in this group, parents should focus on Sierra’s academic results, graduation outcomes, and year-to-year trends rather than comparisons among nearby schools.

The school’s clearest academic strength is English Language Arts. In 2025–2026, 62.5% of students were proficient in ELA, about 10 percentage points above the Washington average of 52.81%. This was a notable improvement from 51.72% the previous year. Mathematics is the largest concern: 26.47% of students were proficient, compared with 43.11% statewide. Science results were also below the state average, with 37.5% proficient compared with 50.95% statewide, following a substantial decline from the prior year. For parents, this means Sierra offers encouraging ELA performance but would benefit from stronger academic support in math and science.

Student completion outcomes are somewhat more positive than the test scores. Sierra’s 2024–2025 graduation rate was 83.5%, slightly above Washington’s 82.6%, while its dropout rate was 8.9%, below the state rate of 9.8%. The school’s ranking improved from the 36th percentile in 2024–2025 to the 46th percentile in 2025–2026, though it remained below its 70th-percentile result from 2023–2024. Overall, Sierra appears to be a small school with reasonable graduation and student-retention results, strong recent ELA growth, and a clear need to improve math and science instruction. Its small enrollment may also cause scores to vary noticeably from year to year.
