Best High Schools in Zip Code 99685

Zip code 99685 contains exactly one high school, Unalaska Junior/Senior High School, serving grades 6–12 in the Unalaska City School District with 174 students and a student-teacher ratio of 13.1. Because this is the only school in the area, the most meaningful comparisons are against state averages and the school’s own performance history.

Unalaska Junior/Senior High School performs above the Alaska state average in all three core subjects — English Language Arts, math, and science — with particularly strong results in 9th grade math, where 47.83% of students are proficient versus the state’s 17.91%, and in 8th grade science, where 57.14% are proficient versus 35.17% statewide. The school’s all-grade math proficiency is 43.62%, about 11 points above the state, while ELA proficiency is 39.36%, also above the 32.89% state average. The school’s graduation rate is a solid 89.4%. However, its state ranking has been volatile: it ranked #8 (87th percentile) in 2023–2024, dropped to #31 (48th percentile) in 2024–2025, then rebounded to #22 (65th percentile) in 2025–2026. This instability is likely tied to its small enrollment — roughly 25 students per grade level — meaning a handful of students can swing proficiency rates significantly. The one reported grade-level subject where the school falls below the state average is 10th grade science, at 29.63% versus the state’s 33.03%, a dip worth watching.

The Unalaska City School District itself is ranked 9th out of 23 Alaska districts (61st percentile, 4 stars). Only 10.34% of students qualify for free or reduced-price lunch, a low rate that suggests limited economic disadvantage, and per-student spending is high at $23,495, consistent with Alaska’s rural operating costs. Overall, families in this area will find a small, well-funded school that consistently outperforms state averages in math and ELA, with standout grade-level achievements, while keeping in mind that cohort size can cause year-to-year ranking swings.
