Summary:
The San Juan Island School District serves about 794 students across five schools on San Juan Island in Washington: three comprehensive schools — Friday Harbor Elementary School (K–5), Friday Harbor Middle School (6–8), and Friday Harbor High School (9–12) — plus the alternative K–12 Griffin Bay School and the very small Griffin Bay School Open Doors program for grades 10–12. The district overall ranks 34th of 238 in Washington (86th percentile, 4 stars), and that rating applies district-wide, not to each individual school.
Among the comprehensive campuses, Friday Harbor High is the academic standout, ranking 60th of 396 statewide (85th percentile, 4 stars) with all-grade ELA at 75.38% and math at 53.85%, both above district and state, plus a 93.0% graduation rate; its 10th-grade math (53.85%) far exceeds the state's 35.42%. Friday Harbor Middle is the most consistent improver, rising from the 64th to the 73rd to the 74th percentile and now ranking 135th of 514 with 4 stars, with 7th-grade math at 61.67% versus the state's 41.31%. Friday Harbor Elementary has climbed from the 58th to the 65th percentile but remains at 3 stars, with math above state while ELA and science trail state.
Two cautions stand out. Science fell sharply across the district from 68.97% to 48.26%, with all three comprehensive schools declining, leaving district science below the state's 50.95%. Also, the high school's strong math followed a 28.57% result the prior year — a rebound rather than a steady pattern. The alternative and Open Doors schools have too little unsuppressed data to judge: Griffin Bay reports 33.33% in math with ELA and science suppressed, and Open Doors has only 6 students and no usable test scores. Per-student spending ranges widely, from $8,565 at Open Doors to $21,298 at Friday Harbor High.
