Summary:
Summit Public School: Atlas is the only high school in the Summit Public School: Atlas area, serving students in grades 6–12 in Seattle, Washington. The school enrolls 566 students, has a 16.6-to-1 student–teacher ratio, and received a four-star rating while ranking in the 76th percentile statewide in 2025–2026. With no other high schools in this list, Atlas is the sole option for comparison in the area.
For parents, the strongest result is the school’s 94% graduation rate in 2024–2025, which matched the district rate and was 11.4 percentage points higher than Washington’s rate. Academic performance, however, varies considerably by grade. Tenth graders performed above the state average in both English language arts and math, while seventh-grade math also stood out. Tenth-grade math proficiency was 50.91%, compared with 35.42% statewide, and tenth-grade ELA proficiency was 70.91%, compared with 64.41% statewide. These results suggest that the school’s older students are showing particular academic strength.
The main areas for attention are the middle grades and the school’s recent overall decline in test performance. In 2025–2026, Atlas was below state averages across all grades in ELA, math, and science when results were combined. Sixth-grade ELA and math, along with eighth-grade ELA, were especially weak relative to the state. All-grade proficiency also fell from the prior year in ELA, math, and science, coinciding with a ranking decline from the 87th to the 76th percentile. Parents should view Atlas as a school with strong graduation outcomes and notable tenth-grade results, while asking about support for younger students, recent academic trends, and how the school is addressing the decline.
