Summary:
ZIP code 99101 has one elementary-level school, Summit Valley School, a small rural school in Addy serving 108 students from prekindergarten through eighth grade. Because it is the only school in the ZIP code, there are no direct school-to-school comparisons available. The school has a 17:1 student-teacher ratio, and 86.11% of students qualify for free or reduced-price lunch, indicating that many families may benefit from additional academic and support services.
In 2025–2026, Summit Valley students performed below Washington averages in all reported subjects. Overall proficiency was 21.88% in English language arts, 23.44% in math, and 35% in science, compared with statewide rates of 52.81%, 43.11%, and 50.95%. English language arts is the clearest area for improvement: performance did not change from the prior year, and the school’s reported fifth- and sixth-grade results were also below state levels. Math and science showed more encouraging progress, increasing by 6.25 and 8.91 percentage points, respectively. Small grade-level groups and suppressed results for several grades mean that individual percentages may change significantly from year to year.
Families should also consider the school’s recent ranking history. Summit Valley fell from the 51st percentile and three stars in 2023–2024 to the 20th percentile and one star in 2025–2026. The associated Summit Valley School District ranks 209th of 238 Washington districts, at the 12th percentile. The most important questions for prospective families are how the school is strengthening reading instruction, whether recent math and science gains are continuing, and what individualized supports are available in this small PK–8 setting.
