Cornerstone Collegiate Academy of Seoul

A small co-ed American Christian college-preparatory school in Seocho-gu running grades 1 to 12 with AP as the leaving qualification.

CCAS positions itself as a faith-based community school rather than a name-brand international option. Daily Bread sessions sit alongside an English-medium American programme several times a week, and accreditation comes from the Association of Christian Schools International and the National Council for Private School Accreditation rather than the WASC, CIS or IB networks. CCAS is also a registered SAT testing centre.

Independent third-party voice is thin. The clearest read is that this is a small operation pitched at families who want explicit Christian formation alongside an American academic track, with character development at the centre of the mission. Facilities and cohort breadth are leaner than the established Seoul international schools, so families should walk the campus, ask about university destinations, and talk to current families before committing for the long haul.

• One commenter grouped Cornerstone with Saint Paul Preparatory and Fayston Preparatory as Seoul schools operating in a "Legal Gray Area", citing questionable accreditations and profit-driven priorities. The school holds AI and NCPSA accreditation and is an SAT testing centre, but is not on the Korean Ministry of Education list of officially designated foreign schools.
• Glassdoor employee reviews describe an organised environment with supportive teachers and well-behaved students, alongside concerns that administration clamps down on negative behaviour quickly and ignores teacher feedback.
• Independent parent voices are scarce. The International Schools Database parent and student review count is zero; Expat Schools Korea carries one drive-by 2-of-5 entry from 2019 commenting on facilities.
• Tuition is reported at roughly USD 24,000 per year in fan communities, which discuss the school in relation to a tripleS member's enrolment.
