Summary

Chief Sealth International High School is a large public school serving grades 9–12 in southwest Seattle, with 1,184 students and a diverse, economically mixed enrollment in the Seattle School District No. 1.

The school’s statewide standing has improved substantially, rising from the 24th percentile in 2023–2024 to the 60th percentile in 2025–2026 and earning a three-star rating. English Language Arts is a relative strength: 58.79% of students were proficient, above the Washington average of 52.81%, although below the district average. Science has shown the most impressive recent growth, increasing from 30.1% proficiency in 2023–2024 to 56.88% in 2025–2026, slightly above the state result. The school also shows strong recent effectiveness rankings for English Language Learners and students receiving special education services.

Math remains the clearest academic challenge. Only 28% of students were proficient in 2025–2026, well below both district and state averages. Graduation was 85.5% in 2024–2025—above the state rate but slightly below the district—and the dropout rate rose to 10.0%, making student persistence an important concern. Compared with nearby comprehensive schools, Cleveland High School STEM and West Seattle High School report stronger graduation, math, and English results. Chief Sealth generally outperforms Evergreen High School, while Raisbeck Aviation High School is a specialized, selective program and not a direct comparison. Overall, Chief Sealth appears to be improving, with math, graduation, and dropout trends needing the closest attention.
