Summary:
ZIP code 98831 has one listed high school, Manson High School, serving grades 9–12 in the small community of Manson. The school enrolls about 220 students and is part of the Manson School District. Its small size and 16.9-to-1 student-teacher ratio may support personal attention, although small graduating and testing groups can also cause year-to-year percentages to change substantially.
The clearest strength is graduation: 95.0% of students graduated in 2024–2025, matching the district and exceeding Washington’s 82.6% rate. English Language Arts is another relative strength. In 2025–2026, 54.55% of students met the all-grades ELA standard, above the district’s 46.96% and the state’s 52.81%. However, ELA performance declined from 61.9% the previous year, and the 10th-grade result was below the state average. Mathematics is the most important area for improvement. Only 22.22% of students met the latest all-grades math standard, compared with 39.39% in the district and 43.11% statewide. Math performance also fell from 40.48% the prior year. Families may want to ask about math course results, intervention programs, and student participation rates when interpreting this change.
Science results for 2025–2026 were suppressed, so the school’s current performance cannot be determined from the available data; a suppressed value should not be treated as zero. In 2024–2025, Manson’s science proficiency was 48.39%, close to the state’s 49.38% and above the district’s 43.95%. About 61.82% of students qualified for free or reduced-price lunch, providing important context for planning student supports, while reported per-student spending was $18,895 in 2023–2024. School rankings have varied, from the 59th percentile in 2024–2025 to the 33rd percentile in 2025–2026, so subject-level results and graduation data offer more useful guidance than rankings alone.
