Summary:
ZIP code 98250, centered on Friday Harbor and served by the San Juan Island School District, has two high-school options: Friday Harbor High School for grades 9–12 and Griffin Bay School Open Doors for grades 10–12. The schools are very different in size and purpose: Friday Harbor enrolls 255 students, while Griffin Bay serves only six students through a small, specialized Open Doors program.
Friday Harbor High School is the stronger choice based on the available academic and graduation data. It ranked 60th of 396 Washington high schools, placing it in the 85th percentile and earning four stars. Its 2024–2025 graduation rate was 93%, well above both the district’s 83.3% and the state’s 82.6%. Current testing shows especially strong English Language Arts performance: 75.38% of students were proficient, compared with 58.91% districtwide and 52.81% statewide. Math proficiency was 53.85%, above district and state levels, following a substantial increase from the prior year. Science was 50.91%, roughly equal to the state, although the school recorded a much stronger 80.39% science result the year before. These year-to-year changes suggest parents should consider multiple years of information rather than relying on one test cycle.
Griffin Bay School Open Doors should not be judged directly against the larger high school. Its six-student enrollment indicates a distinct program model, and its test results are suppressed, meaning the available data do not show whether performance was strong or weak. Both schools share the favorable context of a district ranked 34th out of 238 Washington districts, in the 86th percentile. For most families seeking a conventional high-school experience, Friday Harbor offers the more complete set of published outcomes, strong graduation results, and broad academic data. Griffin Bay may be relevant for students who need or prefer its specialized program structure.
