Summary:
ZIP code 98290 in Snohomish, Washington, contains three high schools serving grades 9–12 — Snohomish High School, AIM High School, and High School Re Entry — all operated by the Snohomish School District, with a combined enrollment of 1,710 students. Enrollment is very uneven: Snohomish High enrolls 1,496 students, or 87.5% of the ZIP total, while AIM High enrolls 174 and High School Re Entry only 40. The two smaller schools share an address and appear to serve alternative or re-entry populations, so their results are best understood on their own terms rather than compared directly with the large comprehensive high school.
Snohomish High School posts the strongest outcomes here. Its 2024–2025 graduation rate is 95.1%, above the district's 90.0% and the state's 82.6%, and its 2.7% dropout rate is well below both. Science is a clear strength at 67.84% proficiency in 2025–2026, above the district's 59.88% and the state's 50.95%. ELA is above the state but below the district, and math trails the district in both years. Its rank percentile eased from 79 to 70 between 2024–2025 and 2025–2026, still a solid 4-star result.
AIM High School is improving from a low base, rising from the 10th to the 36th percentile and gaining in ELA, math, and science, yet math proficiency is still just 25% versus the district's 52.8%, and its graduation rate is 63.7% with a 15.3% dropout rate. Its free/reduced lunch rate is 41.38% and per-student spending is $23,253. High School Re Entry, with 40 students, has the highest free/reduced lunch rate (55%) and lowest spending ($6,123); its 2025–2026 ELA and math scores are suppressed by the state for privacy, meaning those results are unknown, not zero.
