Understanding international school admissions in Seoul requires grasping one rule that surprises many arriving families: South Korea regulates who may attend foreign schools. This 2026 guide explains the eligibility requirements, application timelines, documents and realistic costs in KRW, so your family can plan a smooth landing in one of Asia's most dynamic capitals.
Who Can Attend an International School in Seoul
Most of Seoul's established international schools are licensed as foreign schools, which means admission is generally limited to children holding a foreign passport, or Korean nationals who have lived abroad for a defined period — typically three years or more. Schools verify this strictly with passports, visas and entry-exit records. Dual nationals usually qualify through their foreign passport. If your child is a Korean citizen without overseas residence history, your options narrow to internationally minded private Korean schools — confirm eligibility with each school before investing time in an application.
Seoul's Leading International Schools
Seoul Foreign School
Founded in 1912 in Seodaemun, Seoul Foreign School is the city's most established international school, offering the IB continuum alongside a British-stream primary. Its century-old campus community and strong university placement make it the first application for many Western families.
Seoul International School
South-east of the city in Seongnam, Seoul International School delivers an American curriculum with extensive AP offerings. Academics are rigorous and results outstanding; applications concentrate heavily in spring for August entry.
Dulwich College Seoul
Dulwich College Seoul brings the British independent-school tradition to the Banpo district, teaching the English National Curriculum, IGCSEs and the IB Diploma. Its central river-south location suits families based in Seocho and Gangnam.
Yongsan International School of Seoul
In the heart of the expat-friendly Yongsan district, Yongsan International School of Seoul offers an American programme with a Christian ethos and AP courses. Proximity to Itaewon and the international business district keeps demand high.
Application Timeline for 2026–27
- September–December 2025: shortlist schools, attend tours, prepare documents.
- January–March 2026: main application window; popular grades reach capacity.
- March–May 2026: assessments, interviews and first-round offers.
- June onwards: rolling admissions against remaining places; corporate turnover does open mid-year seats.
Documents and Assessments
- Passports for child and parents, visa or ARC details, and proof of overseas residence where eligibility depends on it.
- Two to three years of school records, translated into English.
- Confidential teacher recommendations — usually English and maths at secondary level.
- Standardised test results where available (MAP, ISA, SSAT depending on school).
- Application fees of KRW 300,000–500,000 per school, non-refundable.
Assessments range from play-based observation at kindergarten to MAP testing and writing samples at secondary. English-language support exists but is capacity-limited — EAL availability often decides borderline applications, so apply early if your child is building English.
Tuition and Costs in KRW (2026)
Seoul's international schools charge among Asia's higher fees: expect roughly KRW 30–45 million per year at elementary level and KRW 38–50 million at high school across the established schools, plus one-off facility or capital fees of KRW 1–5 million and bus services of KRW 2–4 million annually. Most corporate packages in Korea include education allowances — confirm the cap before assuming full coverage, as top-band tuition can exceed older allowance levels.
Practical Tips for Expat Families
- Match district to school: Seoul traffic is serious; Yongsan and Seocho families look south-central, while Seodaemun suits the north-west.
- Prepare eligibility evidence early: entry-exit certificates and apostilled documents take weeks to assemble from abroad.
- Apply to two or three schools: waiting lists move constantly with corporate rotations.
- Ask about Korean language: the strongest schools integrate Korean culture and language — an asset your children will carry for life.
