Best International Schools in Seoul 2026

Seoul has one of the most developed international school landscapes in Asia. With over 30 internationally accredited schools serving the city’s large expatriate population, choosing the right one requires careful thought about curriculum, location, ethos, and fit.

This guide ranks Seoul’s leading international schools and explains what makes each one stand out.

1. Korea International School (KIS)

Curriculum: American + IB | Location: Pangyo (Seongnam) + Jeju | Fees: KRW 35M–42M/year

KIS consistently ranks as South Korea’s most sought-after international school. Its WASC accreditation, strong AP and IB programmes, and exceptional university placement record — including regular admits to US Ivy League universities — make it the benchmark for international education in Korea. The Jeju campus offers full boarding.

For families who can secure a place, KIS represents the gold standard of international education in South Korea.

2. Seoul International School (SIS)

Curriculum: American | Location: Seongnam | Fees: KRW 33M–40M/year

One of Korea’s oldest and most established accredited schools, SIS has built a reputation over decades for rigorous academics and exceptional US college counselling. The school’s community is predominantly North American, and its results speak for themselves — graduates consistently gain admission to highly competitive US universities.

SIS is a particularly strong choice for families whose children plan to pursue higher education in the United States.

3. Dulwich College Seoul

Curriculum: British (IGCSE + A-Level) + IB | Location: Mapo-gu | Fees: KRW 30M–38M/year

Part of the global Dulwich College International Schools network, Dulwich Seoul offers the British curriculum alongside IB options. The school is a natural fit for British and European families, and for those targeting UK university admissions. Dulwich’s performing arts programme is particularly strong, reflecting the heritage of Dulwich College London.

The school’s position within the DCIS network also benefits families who may relocate again — Dulwich has campuses across Asia.

4. Seoul Foreign School

Curriculum: British (IGCSE + A-Level) | Location: Yongsan | Fees: KRW 28M–36M/year

Founded in 1912, Seoul Foreign School is one of the oldest international schools in Korea. Its long history has created a strong alumni community and deep roots in Seoul’s British expat population. The school is smaller than KIS or SIS, which many families regard as a strength — class sizes are modest and the community is genuinely close-knit.

SFS is an excellent choice for British curriculum families who value tradition and community alongside academic quality.

5. Chadwick International

Curriculum: American + IB | Location: Songdo (Incheon) | Fees: KRW 26M–34M/year

Located in Songdo International Business District — 30 minutes from central Seoul — Chadwick International is affiliated with Chadwick School in California. It offers one of the few genuine boarding options in the greater Seoul area, with modern purpose-built facilities and a strong IB programme.

Chadwick is an increasingly popular choice for families based in western Seoul, Incheon, and those whose children benefit from a boarding environment.

---

6. North London Collegiate School Jeju (NLCS Jeju)

Curriculum: British (IGCSE + A-Level) + IB | Location: Jeju | Fees: KRW 28M–38M/year

While technically on Jeju Island (1 hour from Seoul by air), NLCS Jeju deserves mention as one of the finest British curriculum schools in Asia. Affiliated with North London Collegiate School in London — consistently one of the UK’s top girls’ schools — NLCS Jeju is co-educational and full boarding.

For families willing to consider a boarding school environment, NLCS Jeju is a world-class option.

---

7. Dwight School Seoul

Curriculum: IB exclusively | Location: Mapo-gu | Fees: KRW 22M–30M/year

Dwight School Seoul is part of the global Dwight Schools network, which offers the IB curriculum from Early Years through to the Diploma Programme. The school is a strong choice for families committed to the IB pathway, and its global network facilitates transfers between Dwight campuses in New York, London, and Shanghai.

---

8. Seoul International Christian School (SICS)

Curriculum: American / Christian | Location: Bundang | Fees: KRW 9M–14M/year

For families seeking quality international education at a more accessible price point, SICS is a credible option. The school follows an American curriculum within a Christian framework and has a warm, community-focused environment. It is particularly popular with missionary families and Christian expats.

How to Choose the Right School for Your Family

Curriculum. The choice between American, British, and IB curricula matters most if your child is likely to move schools again, or if you have a specific university destination in mind. American curricula suit US-bound students; British (IGCSE/A-Level) suits UK-bound; IB is the most universally transferable.

Location. Seoul’s traffic and geography mean school location matters significantly. Families in Gangnam/Seocho tend to favour schools in southern Seoul and Pangyo; Yongsan residents often prefer central schools.

Community fit. The nationality mix of the school community affects social life, friendships, and culture. Visit the school, speak to current parents, and consider how your child will fit in.

University destination. If you know where your child plans to go to university, work backwards. US-focused students benefit from AP courses; UK-focused students from IGCSE and A-Levels; internationally mobile students from the IB Diploma.

Apply early. Most of these schools have waitlists. Apply as soon as your relocation is confirmed — ideally 12–18 months before your target start date.
