Summary:
ZIP code 98070 contains two public high schools serving grades 9–12 on Vashon Island: Vashon Island High School and Student Link, both part of the highly rated Vashon Island School District. Together, they enroll 561 students, though the schools differ considerably in size, reported outcomes, and student-support context.
Vashon Island High School is the clear overall standout. It enrolls 511 students and has ranked around the top 4% of Washington high schools for three consecutive years, including 14th of 396 schools in 2025–26. Its 95.1% graduation rate is well above the district’s 90% and the state’s 82.6%. In 2025–26, proficiency reached 89.57% in English language arts, 61.34% in math, and 82% in science, exceeding statewide results in every subject. ELA and science are particular strengths. Math declined by 3.88 percentage points from the prior year, so it is the main area to monitor, although performance remains substantially above the state average.
Student Link is much smaller, with 50 students, and its results should be interpreted cautiously because small cohorts can produce larger year-to-year changes and suppressed test data. In 2024–25, its ELA and math proficiency rates—71.43% and 66.67%—were above statewide levels, while science proficiency was much lower at 30.77%; science improved to 36.36% in 2025–26 but remained below district and state results. The school’s 50% graduation rate is its largest concern, though differences in enrollment size, student needs, and school structure may affect direct comparisons. Student Link also reports a higher FRL rate and greater per-student spending than Vashon, providing important context without indicating school quality by itself.
