Summary:
The Sedro-Woolley School District has one listed middle school, Cascade Middle School, serving students in grades 7–8 in the Sedro-Woolley area of northwest Washington. The school enrolls about 670 students and is located at 905 McGarigle Road in Sedro Woolley. Because it is the district’s only middle school, there are no comparable middle schools within the district; Cascade’s results provide the main picture of middle-school education in the area.
Cascade’s strongest 2025–2026 result was seventh-grade English language arts, with 42.48% of students proficient. Overall, English language arts was the school’s strongest subject at 36.75% proficiency, followed closely by science at 36.61%. Mathematics was weaker, with 28.45% proficient overall, including just 25.86% in eighth grade. Eighth-grade performance was below seventh grade in both English language arts and math. The largest concern was eighth-grade English language arts, where 30.87% were proficient—about 20 percentage points below the Washington average. Across all subjects, Cascade also trailed district and state results, although science showed a small year-over-year improvement.
Parents should also note that the school’s relative ranking declined over the three years shown, moving from the 35th percentile in 2023–2024 to the 27th percentile in 2025–2026, while its rating changed from two stars to one. More than half of students qualified for free or reduced-price lunch in 2024–2025, and the reported student-teacher ratio was 20.1 to 1, providing useful context about the school community and instructional setting. Overall, the clearest priorities are strengthening eighth-grade English language arts, improving math—especially eighth-grade math—and closing the school’s achievement gaps with both district and statewide averages.
