Montesano Junior-Senior High has the strongest overall outcome indicators, including a 94% graduation rate, a 3.4% dropout rate, and a 2025–2026 ranking in the 77th percentile statewide. Its English language arts performance is especially strong: 67.54% of students were proficient, compared with 52.81% statewide. Science also exceeded the state rate. Math is the school’s clearest challenge, with 41.23% proficiency, although that figure improved by 8.20 percentage points in the most recent year. The school serves the largest share of district students and has a student-teacher ratio of 20.4.
Simpson Avenue Elementary is the strongest school in the available elementary academic data, ranking in the 77th percentile and outperforming the state in every reported subject. Its math proficiency rate was 59.29%, 16.18 points above the state, while science reached 63.92%. Third-grade math was particularly strong at 68.89%, though sixth-grade math was lower at 43.02%, making the transition to secondary school worth monitoring. Beacon Avenue Elementary School has the district’s lowest student-teacher ratio and highest per-student spending, but current test results are unavailable, so its academic performance cannot be fairly compared.
