Seoul Foreign School

The oldest and most established international school in Korea, a non-profit IB school in Yeonhui-dong with a separate British primary track and a Christian ethos that runs through the community.

SFS was founded in 1912, holds WASC, CIS and ACSI accreditation and is approved as a British School Overseas. Elementary families choose between an IB Primary Years stream and a British primary stream using the English National Curriculum and IPC framework, before converging on the IB Diploma in high school. Headline IB results sit well above the world average and the school sends a steady share of leavers to top US and UK universities.

Fees sit at the top of the Seoul market, around 30 to 40 million won per year, and families regularly compare SFS, SIS, KIS and Dwight. SFS is the smaller and more close-knit of the big three. The Christian ethos and chapel culture matter to some families and push others elsewhere. Recurring concerns centre on cost-to-value at the top end and the social mix between wealthy Korean families and the broader expat community in middle school.

• The reference school in Seoul. International-teacher and Korea expat threads put SFS at the top of the city consistently and call it the closest thing to a unanimous tier-1 in Korea.
• Faculty depth is the most-cited reason. Teachers describe a strong package, low turnover, two-thirds of staff with master's degrees and recruitment from a wide international pool. One teacher said a friend who works there raves about the place.
• The Christian heritage runs deep. The school traces back to missionary families and most of the faculty are Christian. A required religious-studies class and a high baseline of staff faith come up repeatedly.
• Alumni mostly remember it positively: one called it competitive but positive, another said second grade involved more reading and homework than first-year medical school. The recurring caveat is the bubble effect, with one alum describing students as sheltered, even by international-school standards.
• Outcomes-driven parents care about university placement. SFS sends large numbers to top US schools each year; the senior-decisions list is widely shared in Seoul college-application threads.
