Best Public Schools in Zip Code 98855

Schools in ZIP code 98855 include five public schools serving elementary through high school, alternative, and choice-school students in the Tonasket School District, with about 1,104 students overall. The area is relatively rural and serves a high-need student population, with free or reduced-price lunch rates generally above 68%. School rankings have improved at several campuses, although the district remains below the state academically overall.

Tonasket High School stands out for English language arts, where 61.67% of students were proficient in 2025–2026—higher than both the district and state rates. Its 89% graduation rate is also stronger than the state average. However, math is a major concern, with only 18.33% proficiency, and science declined from the prior year. Tonasket Elementary School shows the most consistent improvement over time: its ranking rose from the 10th to the 17th percentile over three years, while ELA, math, and science scores all improved year over year. It has the strongest reported math performance in the area, at 37.26%, though that remains below the state average.

Tonasket Middle School has also improved in ranking and performs best in science, at 43.66%, slightly above the district rate. Math remains weak across all middle-school grades. Tonasket Outreach School serves an alternative population; its math score improved, but its ELA result fell, so comparisons with traditional schools should be cautious. Results for the small Tonasket Choice High School are suppressed and cannot be meaningfully evaluated. Overall, math in grades 6–12 is the clearest area needing attention, while high-school ELA, elementary improvement, and middle-school science are encouraging strengths.
