Summary:
ZIP code 98070, on Vashon Island in Washington, has one middle school serving grades 6–8: McMurray Middle School, with 355 students. Because there is only one middle school in the ZIP code, families cannot make a direct local school-to-school comparison. The most useful benchmarks are the school’s performance against the Vashon Island School District, Washington state, and McMurray’s results over time.
McMurray is a strong-performing school statewide. In 2025–26, proficiency was 64.17% in English language arts, 65.77% in math, and 68.50% in science. These results were 11.36, 22.66, and 17.55 percentage points above Washington averages, respectively. Math is the school’s clearest strength and the only subject in which it exceeded the district overall. Sixth-grade math was especially strong at 70.77%, while seventh-grade math was lower at 58.77% but still well above the state result. Science matched the district’s 68.50% result, while ELA was 4.88 points below the district; this reflects comparison with an unusually strong district ranked seventh out of 238 statewide, rather than weak school performance.
The school’s ranking history suggests sustained success: it ranked between 51st and 58th among Washington middle schools over the last three reported years, placing it around the 89th–90th percentile. Parents should also note that ELA declined 4.50 points from the prior year, and science declined 2.14 points, while math improved 1.51 points. ELA results gradually decreased across grades, from 66.41% in sixth grade to 62.02% in eighth grade, making literacy the main area to monitor. McMurray reports a 19.5-to-1 student-teacher ratio, 23.1% of students qualifying for free or reduced-price lunch, and $18,890 in spending per student in 2023–24.
