Summary:
ZIP code 99101 has one listed school, Summit Valley School, a small Pre-K–8 elementary school serving 108 students in the Addy area through the Summit Valley School District. Because it is the only school in the ZIP code, parents cannot compare local schools directly. The school’s 17:1 student–teacher ratio and broad grade span may appeal to families seeking a small-school setting where children can remain in one school through eighth grade.
Academic results were below Washington averages in all three reported subjects during 2025–2026. English Language Arts proficiency was 21.88%, compared with 52.81% statewide, making literacy the clearest area of concern; the school’s ELA rate was unchanged from the prior year. Math proficiency was 23.44%, versus 43.11% statewide, but improved by 6.25 percentage points. Science was the school’s strongest subject at 35%, compared with 50.95% statewide, and improved by 8.91 points. Among reported grade-level results, third-grade math was strongest at 40%, while sixth-grade math was weakest at 18.75%. Several grade-level results were suppressed to protect privacy, so they should not be interpreted as zero performance.
The school serves a student population with substantial economic need: 86.11% of students qualified for free or reduced-price lunch, and reported per-student spending was $17,441 in 2023–2024. The school’s displayed statewide ranking declined from the 51st percentile and three stars in 2023–2024 to the 20th percentile and one star in 2025–2026, although rankings can change for reasons beyond year-to-year test scores. For parents, the main considerations are the school’s small, continuous PK–8 environment, recent improvement in math and science, and need for stronger ELA performance. Families may also want to ask about literacy support, sixth-grade math instruction, class sizes, and programs that sustain the recent academic gains.
