Summary:
Zip code 99577 (Eagle River, Alaska) is served by one middle school, Gruening Middle School, which enrolls 797 students in grades 6 through 8 as part of the Anchorage School District.
Gruening Middle School is the only middle school in this zip code, so there are no nearby local schools for direct comparison. However, it stands out as a high performer against district and state benchmarks across every subject. In the 2025–2026 school year, math proficiency reached 55.74%, far surpassing the district's 35.66% and the state's 32.20%. The school's 8th-grade math results are especially striking, with 62.55% proficiency—nearly double the statewide average. Science proficiency is also strong at 50.62%, well above district and state levels, though it declined by about 4 points from the prior year. English language arts proficiency sits at 44.52%, which is above district and state averages but remains the school's relative weak spot. Notably, 7th-grade ELA proficiency is just 36.00%, significantly trailing the 6th-grade (47.97%) and 8th-grade (48.96%) results, pointing to a possible cohort-specific challenge. The school has earned 4 out of 5 stars for two consecutive years, ranking 25th out of 90 Alaskan middle schools in 2025–2026 after ranking 21st out of 94 the prior year.
With a free/reduced-price lunch rate of just 19.57%, the school serves a relatively affluent community, and its student-teacher ratio of 28.2:1 is high. These factors provide useful context, but they do not diminish Gruening's consistently strong academic record—particularly in mathematics, where proficiency improved by nearly 6 points year over year. For parents in Eagle River, Gruening Middle School offers a well-above-average education by Alaska's standards. The clearest opportunities for improvement are in 7th-grade reading and in stabilizing science scores, but overall this is a top-quartile school with clear strengths in math and a solid track record over the past three years.
