Summary:
ZIP code 98855 has two high schools serving grades 9–12: Tonasket High School and Tonasket Choice High School. Both are operated by the Tonasket School District and together enroll 302 students. The main high school serves 280 students, while the Choice school serves 22, so the two schools offer very different settings and student populations.
Tonasket High School has the more complete set of available performance data and shows a mixed but improving profile. Its strongest subject is English Language Arts, with 61.67% of students proficient in 2025–26, above both the district’s 39.07% and the state’s 52.81%. Math remains the biggest challenge: proficiency rose from 7.69% to 18.33%, but the latest result was still below the district and state. Science proficiency was 42.37%, nearly matching the district but below the state. The school’s 2024–25 graduation rate was 89.0%, higher than Washington’s 82.6% and slightly below the district’s 90.3%. Its ranking percentile also improved from 31 to 41.
Tonasket Choice High School is much smaller and reports a higher free-or-reduced-price lunch participation rate: 86.36%, compared with 71.07% at Tonasket High School. Its academic results are suppressed because of the small number of students, so the available information cannot support a fair performance comparison. Per-student spending was $19,861 at Tonasket High School and $16,284 at Tonasket Choice High School; this difference may reflect enrollment, programs, and staffing rather than school quality alone. Overall, parents will find the main high school offers more measurable academic information, strong ELA and graduation results, and a clear need for continued math improvement.
