Summary:
Summit Public School: Atlas is the only school in this area, serving 566 students in grades 6–12 at 9601 35th Avenue SW in Seattle, with a 16.6-to-1 student–teacher ratio and a 4-star rating.
For parents, Atlas’s strongest result is its 94.0% graduation rate, matching the rate reported for the Summit Public School: Atlas district and exceeding Washington’s 82.6% rate. The school also had especially strong results among older students: 70.91% of 10th graders were proficient in English language arts, compared with 64.41% statewide, while 50.91% were proficient in math, 15.49 percentage points above the state. Seventh-grade math was another bright spot, with 51.79% proficiency compared with 41.31% statewide. Atlas has maintained a 4-star rating in each of the three listed ranking years and has generally ranked above most schools in its comparison groups.
Recent test results are more mixed. In 2025–2026, Atlas was below statewide averages in all-grade English language arts, math, and science, and results declined from the prior year in each subject. Middle-grade performance is the clearest area for improvement: sixth-grade English and math results were each about 11 points below the state, while eighth-grade results were also notably lower. Science was 5.98 points below the state overall and had the largest year-over-year decline. Because Atlas is the only school listed, there is no nearby-school comparison; parents should weigh its strong graduation outcomes and upper-grade performance alongside the uneven middle-grade results and recent academic decline.
