How many American schools in Seoul
American curriculum is the dominant international stream in Seoul, with around eight WASC-accredited schools operating across the metropolitan area in 2026. The cluster splits into three groups. The first is the long-established anchor pair of Seoul Foreign School in Yonhi-dong and Yongsan International School of Seoul in Hannam-dong, both founded for the diplomatic and missionary communities in the early twentieth century and the early 1990s respectively. The second is the Korea International School cluster, with the Seoul Campus in Gaepo-dong, Gangnam serving the southern Seoul base. The third is the suburban and Incheon cluster: Seoul International School in Seongnam, Gyeonggi-do, plus the smaller American Christian schools and Asia Pacific International School in Gangbuk.
Total American curriculum enrolment across the eight schools runs at roughly 5,200 students in 2026, which makes American curriculum by some distance the largest international stream in the city. The cohort mix is heavy on returnee Korean families with US passports or three-year overseas residency, and supplemented by the diplomatic, military and corporate-tied American expat communities. Korean nationals without overseas residency cannot enrol at the in-Seoul American schools, by virtue of the MOE foreigners-only restriction, but Korean nationals can enrol freely at Chadwick International in Songdo and at the AP-track Korea International School Jeju Campus.
The American curriculum sixth form pathway from Seoul leads predominantly to US universities, with WASC accreditation giving Seoul American school transcripts equal standing to a US domestic high school transcript in the Common Application process. UK university entry from AP requires four or five AP courses at grade 4 or 5, and Korean universities admit AP students through their international admissions tracks. For the wider context see our Seoul city hub and the global American curriculum hub.
Fees and the US-curriculum cost ladder
Tuition at Seoul American schools ranges from KRW 31 million per year at lower elementary, to KRW 45 million per year at Grade 12 in 2026. In US dollar terms that is roughly USD 23,000 to USD 33,000. Capital or development fees of KRW 7 million to KRW 14 million on entry, transport of KRW 3 million to KRW 5 million, lunch around KRW 1.5 million, and AP examination fees at KRW 130,000 per exam in Grades 11 and 12 sit on top. The all-in cost-of-place at Seoul Foreign School or YISS at Grade 12 runs around KRW 52 million per year, or USD 38,000.
The fee ladder follows a clear sequence: smaller suburban or specialist American schools at the lower end of the range, anchor international schools at the top. Most schools operate corporate fee schemes for multinational employers and US Department of State scheme placements for diplomatic and military families. Seoul Foreign School and YISS run small need-based bursary programmes for long-term Korean and US passport-holding families.

Illustrative example schools
The four schools below are illustrative, not a ranking. Each runs a long-established American curriculum programme with a distinct identity in the Korean international school market.
Seoul Foreign School in Yonhi-dong, Seodaemun district, is the oldest international school in Korea, founded in 1912. SFS runs a parallel American AP and IB Diploma sixth form, with families able to choose between the two routes at Grade 11. The largest sixth-form cohort by combined AP and IB count, with a long record of placements at Ivy League, Russell Group, Stanford and Korean SKY universities. The northern Seoul location anchors the diplomatic, embassy and consulate family base.
Yongsan International School of Seoul in Hannam-dong, central Seoul, runs a pure American curriculum from K through Grade 12 with AP as the sixth-form anchor. The campus sits adjacent to the former US military base in Yongsan, and the YISS cohort historically included a heavy concentration of US military and contractor families. With the US base now closed, the family mix has shifted toward the corporate-tied and returnee Korean cohort. Strong AP scores and a substantial extracurricular programme.
Korea International School Seoul Campus in Gaepo-dong, Gangnam, is the southern Seoul anchor of the KIS network, with its sister campus in Pangyo and the Jeju campus on Jeju Island. The Seoul Campus runs American curriculum K through Grade 12 with AP, in modern facilities in central Gangnam. The cohort is heavily returnee Korean with US passport holders, with strong AP results and a notable US university placement record.
Seoul International School in Seongnam, Gyeonggi-do, sits in the southern suburb of Bundang and serves the southern Seoul and northern Gyeonggi family base. American curriculum K through Grade 12 with AP, founded 1973, and a long-established WASC-accredited identity. The Bundang location appeals to families based in the southern Seoul corridor, with the standard YISS or KIS Seoul commute proving impractical from south of the Han River.
Where American curriculum families live
American curriculum families in Seoul cluster around four anchors. Hannam-dong, Itaewon and Yongsan for families using YISS, with the diplomatic quarter, the former US military base and the long-established American expat residential infrastructure concentrated here. Three-bedroom family apartments run KRW 5 million to KRW 9 million per month in this central cluster. Yonhi-dong and the northern Seoul districts for families using Seoul Foreign School, with single-family villas and high-rise family apartments around Yonsei University at KRW 4 million to KRW 7 million per month.
Gangnam, Gaepo-dong and Daechi-dong for families using KIS Seoul Campus, where the southern Seoul corporate and returnee Korean family base concentrates. Apartment rents run KRW 4 million to KRW 8 million per month for three-bedroom units, with the Daechi-dong cluster also serving the heavy domestic Korean academic tutoring market. Bundang and Pangyo in southern Seongnam for families using Seoul International School and KIS Pangyo, where newer apartment stock and family-oriented suburban infrastructure run KRW 3 million to KRW 6 million per month.

Admissions, F-visa rules and the AP-IB choice
Seoul American schools apply the same Korean MOE foreigners-only enrolment rule as other international schools in the city. Foreign passport holders are eligible without restriction. Korean nationals are eligible only if they have lived overseas for at least three consecutive years at the point of application. Returnee Korean families are the largest single cohort at most Seoul American schools, particularly at Grade 9 and Grade 11 entry points where Korean middle school graduates re-enter the international system. Applications for August 2026 entry opened in October and November 2025 with assessment days through January and February, and offers issued by mid-March. Mid-year transfers are accepted on a rolling basis through Grade 8 subject to places.
The AP versus IB choice at Seoul Foreign School and the Seoul American cluster is the most consequential sixth-form decision an American curriculum family makes. AP suits students applying primarily to US universities, with the flexibility to take exam subjects independently of formal courses, and the standardised College Board score grading that US admissions officers expect. IB Diploma suits students applying to UK, European and Asian universities, with the holistic profile and CAS, TOK and Extended Essay components carrying weight beyond the subject grades. Most Seoul American school sixth-form cohorts now split roughly 70 percent AP and 30 percent IB.
