Summary:
Zip code 99577 is served by exactly one high school: Eagle River High School, a grades 9-12 campus with 771 students located in Eagle River, Alaska. Because it is the only high school in the zip code, it is the primary neighborhood option for local families, and its results stand out as strong relative to both the Anchorage School District and Alaska overall. The district is ranked 11th out of 23 Alaska districts (52nd percentile, 3 stars), yet the school consistently beats district averages.
Eagle River's biggest strength is its graduation rate: 96.7% in 2024-2025, compared with 83.2% for the Anchorage School District, a 13.5-percentage-point advantage. The school also climbed to 8th place out of 62 Alaska high schools in 2025-2026 (87th percentile, 4 stars), up from 20th the year before. That same year, proficiency rates surpassed district and state averages in every subject: science 50.31% (district 34.92%, state 33.03%), English language arts 44.24% (district 36.91%, state 31.23%), and 9th-grade math 40.64% (district 23.09%, state 17.91%). The math gap is striking, with proficiency more than double the statewide rate.
Year-over-year gains were strong across every subject, with the largest jump in math (+7.65 percentage points), followed by science (+5.87) and ELA (+3.61). Just a year earlier, math proficiency sat slightly below the district average, so this rapid rebound likely reflects a new cohort of students, instructional improvements, or both. Only 14.01% of students qualified for free/reduced-price lunch, a low economic disadvantage rate that provides helpful context for these strong outcomes. Families should also know that reported scores appear to reflect one tested grade level per subject, 9th grade for ELA and math and 10th grade for science, rather than the whole school. Overall, Eagle River High School offers an excellent graduation rate, a top-10 state ranking, and consistently above-average test performance.
