Best Public Schools in Friday Harbor, WA

Friday Harbor, Washington, has five schools serving students from kindergarten through grade 12, all part of the San Juan Island School District. The area’s schools include one elementary school, one middle school, two high-school programs, and one alternative K–12 school, with 794 students combined. The district ranks in the 86th percentile statewide and has a four-star rating, giving families an overall positive picture of local education.

The strongest traditional school is Friday Harbor High School, which serves 255 students. It ranked in the 85th percentile in 2025–2026, posted a 93% graduation rate, and exceeded state averages in English language arts and math. Friday Harbor Middle School, serving 157 students, also performs well, ranking in the 74th percentile and exceeding state averages in ELA and math. Its seventh grade was particularly strong, while eighth-grade math was comparatively weaker. Friday Harbor Elementary School serves the largest enrollment, with 329 students. It performs best in math relative to the state, but fifth-grade math and ELA deserve attention.

Science is the main improvement area across the three traditional schools. Reported science proficiency declined sharply from the prior year at the elementary, middle, and high schools, although additional years of results are needed to determine whether this reflects a lasting trend. Griffin Bay School serves 47 students in an alternative K–12 setting, so its limited and frequently suppressed data is not directly comparable with the traditional schools. Griffin Bay School Open Doors serves only six students, making reliable evaluation impossible from the available results. Overall, families will find the strongest academic outcomes in the secondary grades, with science and upper-elementary math as the clearest areas to monitor.
