Catholic independent school in Sammamish · grades 6-12 · 819 students (WA State Board of Education, 2024-25) · governed by an independent board of trustees, affiliated with the Archdiocese of Seattle, accredited by the Northwest Association of Independent Schools (NWAIS).
Eastside Catholic sits deliberately between two markets, and its $33,750 tuition (2026-27, grades 6-12) is the tell: far above the archdiocesan parish schools, a meaningful step below Lakeside-tier secular independents. That middle price buys a specific package: a 50-acre campus with a 2,000-seat stadium, more than 40 Advanced Placement (AP) and honors courses, Friday-night football culture, and adult accountability at a scale where nobody is anonymous. Two facts complicate the "Catholic school" label. A majority of students, 55%, are not Catholic, though theology courses and all-school Masses are mandatory for everyone. And the school's most distinctive program, Options, is a dedicated special-education track for students with intellectual and developmental disabilities, something the region's elite preps conspicuously do not offer. Families chasing math-olympiad peer density should note the record leans athletic. Families who want a structured, service-heavy, big-feeling school without a 2,000-student public campus are the target buyer.
