If you’re moving to Seoul — or already here and rethinking your child’s schooling — the list of international schools can feel both exciting and overwhelming. Which one actually fits your family? Can your child even enrol? And what will it really cost? This honest guide walks through seven of Seoul’s leading international schools, with their curricula, real fee ranges, admission rules, and the kind of family each one suits. By the end, you should know exactly what your next step is.
International schools in Seoul: the landscape and the fees
Greater Seoul — including Gyeonggi Province and Songdo in Incheon — is home to more than 40 international schools. They range from Seoul Foreign School, founded in 1912 and Korea’s oldest, to newer campuses offering the full International Baccalaureate continuum. Broadly, you’ll find three curriculum families: American (AP), British (IGCSE and A-Levels), and the globally portable IB. Each opens a different set of university doors, so the “destination” is worth thinking about early.
Fees vary widely: roughly KRW 28M to 66M per year (about USD 20,000 to 48,000). The heritage names sit at the top — Chadwick International in Songdo runs past KRW 50M — while options like Dwight School Seoul are comparatively gentler on the budget. On top of tuition, nearly every school adds registration, a capital or development fee, bus costs, and materials in the first year, so build those into your planning.
The most important — and most overlooked — factor in Seoul is eligibility. Korea’s “foreign schools” are, by law, established to serve foreign nationals. A Korean-citizen child generally qualifies only if they have lived or studied abroad for at least three years, or if at least one parent holds foreign nationality — and even then, Korean nationals are capped at a share of total enrolment (30% in most districts). This matters for two groups. For expat and diplomatic families, spots reserved for foreign passport-holders are the more accessible ones. For returnee (해외 거주 경험) families and mixed-nationality households, the three-year rule and quota decide whether a school is realistically open to you at all. Many locally raised Korean families who want an international education simply cannot enrol — a real constraint worth naming honestly.

How to compare and find the right fit for your family
Even with seven schools side by side, the honest question remains: which one is right for us? It helps to see schools as three types — premium heritage schools, mid-tier and newer campuses, and online international schools — and then narrow by what your family values most: affordability, ease of admission, commute, on-site facilities, and home-language support. Rank those, and the answer starts to reveal itself.
A campus-based international school offers real value — playing fields, facilities, and the irreplaceable experience of being with peers in person. For some families, though, fees or eligibility rules are genuine barriers. If you’d like to start by understanding the learning itself, see how learning works online →.
When fees or the commute are the barrier: an eighth option, online
After reading through seven schools, you may be thinking “I’m not sure we can sustain these fees,” or “we don’t meet the foreign-school eligibility rules,” or “there’s no school within a realistic commute.” Those feelings are completely understandable — and families in exactly that position are who the eighth option, online, is for.
NIJIN GLOBAL ACADEMY (NGA) is an online international school scheduled to open in September 2027. It’s run by NIJIN Inc. in Japan, whose alternative school “NIJIN Academy” already enrols more than 1,000 students.
NGA is built around learning beyond test scores and rankings, with small-group, dialogue-centred classes and a guiding idea: to help children “come to love themselves and the world.” It’s designed for ages 6–18 across Asia and Oceania, and because it’s location-independent, it isn’t bound by Korea’s foreign-school eligibility rules or by how far you live from a campus. Lessons are designed so children can ease into English with their home language as a support — reassuring for families not ready to jump straight into an all-English setting. The goal is tuition around one-fifth of a campus-based international school.
In the interest of honesty: NGA hasn’t opened yet, so there’s no graduate track record to point to — that’s still to come. And an online school can’t replicate everything about a physical campus, from the sports field to the in-person atmosphere. But for families who need it, we want to offer a clear promise: you shouldn’t have to give up on a global education because of a rule, a fee, or a distance.
Frequently asked questions
Q. From what age can my child start?
A. Many campus schools in Seoul admit from ages 2–5 in early-years classes (this varies by school). NGA is for ages 6–18. Whether you want an English environment from the earliest years, or are considering an online option from primary age onward, will shape which schools to look at.
Q. Can returnee or Korean-national children enrol?
A. For Korean-citizen children, foreign schools generally require three or more years of overseas residence or schooling, or a foreign-national parent, and there’s a cap on the share of Korean nationals enrolled. If you don’t meet the criteria, admission may not be possible — always confirm with the school and the relevant education office. Online, NGA is not bound by these nationality requirements.
Q. Is there home-language or transition support?
A. Campus international schools teach mainly in English (or English plus Korean), and structured home-language support varies widely. NGA is designed with home-language support built in, making it easier for families who want to move into English gradually rather than all at once.
Not just “a school you can get into” — a place your child can grow
Seoul has genuinely excellent international schools. It also has real barriers — fees, and eligibility rules that don’t bend for every family. The goal isn’t to settle for whichever school you can technically get into, but to choose, together as a family, an environment where your child can learn as themselves. In that set of choices, a campus and an online school can stand as equals. There’s no need to rush. Whatever your next step, we’re cheering you on.
