How much do international schools cost in South Korea in 2026?

Greater Seoul hosts the densest options: Seoul Foreign School (SFS), Seoul International School (SIS), Korea International School (KIS), Yongsan International School of Seoul (YISS), and British School Seoul. Community fee surveys for recent school years place many premium all-in annual bands roughly between KRW 38 million and KRW 46 million once the published KRW tuition and USD tuition portions are combined. Confirm each school’s live fee PDF; figures revise annually and rise with grade.

Published schedules show the structure clearly. SIS lists full-year tuition with both a KRW line and a USD line by grade, plus application fees around KRW 500,000 and an initial registration fee around KRW 4 million for new students, with optional bus fees near KRW 3 million. SFS similarly splits KRW and USD tuition and adds application, registration, and a large one-time entrance fee (recent schedules show about KRW 5.5 million). Optional buses, lunches, uniforms, and trips commonly lift the year 10-20% above tuition alone.

Gyeonggi corridors such as Suwon and Seongnam sometimes shorten the school run for families who refuse Gangnam rents: Suwon cost of living and Best places for families. Busan and other metros have thinner English-fee options, so a provincial housing win can still force a Seoul school commute or boarding plan.

Many Korean international schools restrict or carefully gate Korean nationals under education rules. Foreign families should still confirm passport and visa eligibility on the admissions page, not on a Facebook rumour. Parent associations then become the social calendar: Expat families community.
