Summary

Sumner High School is a public grades 9–12 school in Sumner, Washington, serving 1,857 students in the highly rated Sumner-Bonney Lake School District, an area with a strong overall school system and access to several nearby comprehensive high schools. Sumner ranks in the 78th percentile statewide for 2025–2026, placing it 87th among 396 Washington high schools. It has remained above the state midpoint for most of the past decade, and its ranking improved from the 72nd percentile the previous year. The school’s strongest overall features are English Language Arts, graduation outcomes, and results for several student groups.

English Language Arts is a clear strength: 77.75% of students were proficient, compared with 72.44% in the district and 52.81% statewide. Sumner’s result was slightly higher than nearby Bonney Lake High School and stronger than Puyallup High School, Gov. John Rogers High School, and other nearby comprehensive schools. Graduation is also strong at 92.8%, well above the 82.6% statewide rate, while the 4.1% dropout rate is less than half the state figure. Sumner’s results for English Language Learners and students from low-income families are particularly encouraging. Its large enrollment makes these outcomes notable, since the school serves more students than most nearby alternatives.

Math and science are the main areas for improvement. Math proficiency was 44.71%, nearly 15.5 percentage points below the district, and science proficiency was 47.61%, below both the district and state. Science has declined steadily in recent years, while ELA has also edged downward despite remaining strong. The most useful benchmark is Bonney Lake High School, which ranks higher overall and currently has stronger math, science, graduation, and dropout results, though Sumner slightly leads in ELA. Special education effectiveness, at the 47th percentile, is another important focus. Overall, Sumner is a strong above-average school with excellent literacy and completion outcomes, but families may want to ask how the school is strengthening math, science, and specialized student support.
