Summary:
Manson High School is the only high school in Manson School District, serving about 220 students in grades 9–12 in Manson, Washington. Because it is the district’s only high school, its results represent the district’s high-school performance. The school serves a community where 61.82% of students qualify for free or reduced-price lunch, has a 16.9-to-1 student-teacher ratio, and spent $18,895 per student in 2023–2024.
The strongest feature of Manson High School is its graduation rate: 95.0% in 2024–2025, compared with 82.6% statewide. This suggests the school does a very good job helping students remain enrolled and complete high school. English language arts is the school’s strongest academic subject. In 2025–2026, 54.55% of students were proficient, slightly above Washington’s 52.81% and well above the district’s 46.96%. The previous year’s ELA result was even stronger at 61.90%, exceeding both district and state results. Science was also reasonably competitive in 2024–2025, although the latest school-level science result was suppressed and cannot be evaluated.
Math is the clearest area for improvement at Manson High School. Math proficiency fell from 40.48% in 2024–2025 to 22.22% in 2025–2026, compared with 39.39% districtwide and 43.11% statewide. The school’s latest ELA result also declined, and its ranking dropped from the 59th percentile and three stars to the 33rd percentile and two stars. These changes may reflect differences among small student cohorts, but the math decline is substantial. For parents, the overall picture is a school with excellent graduation outcomes and comparatively solid ELA performance, but with a pressing need to strengthen math achievement and monitor recent academic trends.
