Seoul is home to one of Asia’s most competitive international school markets, driven by a large expat community from the United States, Japan, the United Kingdom, China, and across Southeast Asia.

For families relocating to Seoul or already living there, understanding the cost of premium international education is an essential first step in the planning process.

Korea International School (KIS)
Korea International School is widely regarded as the flagship premium international school in South Korea. With two campuses — Pangyo (near Seoul) and Jeju (within Jeju Global Education City) — KIS offers an American curriculum alongside IB Diploma Programme options.
The Pangyo campus serves the Seoul metropolitan area and is the most sought-after placement, with a highly competitive waitlist for most year groups. KIS is accredited by the Western Association of Schools and Colleges (WASC) and sends a high proportion of graduates to US universities including Ivy League institutions.
Boarding is available at the Jeju campus, making KIS a rare option in Korea for families seeking a full residential school experience. Annual fees at the Pangyo campus sit in the KRW 35M–42M range depending on grade level, with first-year one-time costs adding KRW 2M–5M.
Seoul International School (SIS)
Seoul International School, located in Seongnam just southeast of central Seoul, is one of Korea’s longest-established accredited international schools. It follows the American curriculum and is WASC-accredited, with a strong reputation for university preparation — particularly for students targeting US higher education.
SIS operates with a clear focus on academic rigour and character development. Extracurricular programmes span sports, arts, debate, and community service. The school community is predominantly North American in character, making it particularly popular with American and Canadian expat families.
Annual tuition ranges from approximately KRW 33M–40M, with additional costs for activities, the school bus, and optional programmes.
Dulwich College Seoul
Part of the global DCIS (Dulwich College International Schools) network, Dulwich College Seoul is located in the Mapo-gu district of western Seoul. The school offers British curriculum (IGCSE + A-Level) alongside IB pathway options, attracting families from the UK, Europe, and beyond.
Dulwich Seoul is known for its strong performing arts provision, modern facilities, and an ethos rooted in the traditions of Dulwich College London — one of England’s most historic independent schools. The school maintains strong links across the global DCIS network, which can be advantageous for families who move between cities.
Annual fees range from approximately KRW 30M–38M depending on year group.
Seoul Foreign School
One of the oldest international schools in Korea, Seoul Foreign School (SFS) has served the expatriate community since 1912. Located in Yongsan, central Seoul, the school follows the British curriculum through IGCSE and A-Level, and has historically been a first choice for British and Commonwealth expat families.
SFS is a smaller school by Seoul standards, which many families regard as an advantage — class sizes are modest and the community is close-knit. The school’s long history means it has deep roots in the expat community and strong alumni connections.
Annual fees run from approximately KRW 28M–36M depending on year group.
Chadwick International
Located in Songdo International Business District (Incheon), Chadwick International is affiliated with Chadwick School in Palos Verdes, California. It sits just 30 minutes from central Seoul and is part of Songdo’s purpose-built international district.
Chadwick offers an American curriculum with IB options and boarding facilities, making it one of the few genuine boarding school options in the greater Seoul area. The campus is modern and purpose-built, with exceptional sports and arts facilities.
Annual fees range from approximately KRW 26M–34M, with boarding adding substantially to the total.
What Drives High Fees in Seoul?
Several factors push Seoul’s premium international school fees to levels comparable with Singapore and Hong Kong:
Real estate. Land and property costs in Seoul — particularly in Gangnam, Pangyo, and Yongsan — are among the highest in Asia. Schools must either own or lease large premises at significant cost.
International teacher salaries. Attracting and retaining internationally certified teachers in Seoul requires competitive packages including salary, housing allowance, flights, and health insurance.
Small class sizes. Premium schools in Seoul maintain low student-to-teacher ratios — often 12:1 or better — which requires more staff per student.
Comprehensive programmes. AP courses, IB examinations, performing arts, international sports tournaments, and global exchange programmes all add to the cost base.
Demand exceeds supply. The number of families seeking premium international education in Seoul consistently outstrips available places, giving schools pricing power.
University Placements
The premium Seoul schools deliver strong university outcomes. Korea International School and Seoul International School regularly place graduates at US Ivy League universities, UC schools, and leading liberal arts colleges. Dulwich Seoul and Seoul Foreign School have strong records to UK universities including Oxford, Cambridge, and the Russell Group.
The international peer network formed at these schools — spanning dozens of nationalities — is an intangible but genuine benefit that many alumni cite as one of the most valuable aspects of their education.
What to Know Before Applying
Apply early. Most premium Seoul international schools have waitlists. For popular year groups at KIS and SIS, families should apply 1–2 years in advance.
Eligibility. Historically, South Korean nationals were restricted from attending international schools. This has been liberalised for Korean nationals with qualifying overseas experience. Verify current eligibility rules directly with the school.
One-time costs. Registration and enrolment fees add KRW 1M–5M+ to first-year costs. Capital levies and development funds may also apply.
Financial aid. Most Seoul premium international schools offer limited financial aid — some employer packages include school fee allowances, which is worth discussing with your HR department before relocating.
