Summary:
ZIP code 98922 has one middle school, Walter Strom Middle School, serving grades 6–8 in Cle Elum within the Cle Elum-Roslyn School District. The school enrolls 206 students, so families should keep in mind that year-to-year results can shift noticeably when the performance of a relatively small group changes. There are no other middle schools in the ZIP code for direct local comparison.
Walter Strom’s strongest recent results are in science and seventh grade. In 2025–2026, 53.45% of students were proficient in science, exceeding both the district rate of 51.46% and the state rate of 50.95%. Science also improved by nearly 10 percentage points from the prior year. Seventh grade was the school’s strongest grade in both tested subjects, with 67.24% proficiency in English language arts and 49.12% in math; both results were above the corresponding state averages. These results suggest that the school has areas of meaningful strength, particularly seventh-grade instruction and science achievement.
The main concerns are overall English language arts and math performance, especially in sixth and eighth grades. Schoolwide ELA proficiency was 43.02%, or 9.79 points below the state, while math proficiency was 37.43%, or 5.68 points below the state. Sixth- and eighth-grade ELA results were substantially below state levels, and both grades also trailed the state in math. Eighth-grade science was a notable exception, performing above the state. The school’s ranking reached the 61st percentile in 2024–2025 but fell to the 52nd percentile in 2025–2026, consistent with the recent ELA and math declines. For parents, the overall picture is mixed: science and seventh grade stand out, while consistent achievement across grades—particularly in ELA and math—appears to be the most important area for improvement.
