King's College International School Bangkok

King's College International School Bangkok opened in 2020. It is the first international school run in partnership with King's College School, Wimbledon, a London independent school founded in 1829, and the two schools developed the curriculum together. The campus is at 727 Ratchadaphisek Road in Yan Nawa district, in the Rama 3 area, which is close to Sathorn and the riverside business district.

The school takes boys and girls aged 2 to 18. Early Years runs from Pre-Nursery to Reception, the Primary School covers Years 1 to 6, and the Senior School covers Years 7 to 13. Teaching follows an enhanced English National Curriculum, with IGCSE examinations in Year 11 and A Levels in the sixth form. Pastoral care is organised through tutors and houses, and a co-curricular programme runs inside and after the school day. The school is a member of FOBISIA and ISAT and has been inspected under the British Schools Overseas framework.

The purpose-built campus covers more than 80,000 square metres. It has an indoor, heated 50-metre saltwater pool, a 625-seat auditorium, 18 science laboratories, design and technology studios, a sports hall with three basketball courts and a climbing wall, a gymnastics centre and a 10,000 m² artificial-turf football pitch. For 2026–27, annual tuition runs from THB 636,500 in Pre-Nursery to THB 999,000 in Years 7–9 and THB 1,098,500 in Years 10 and 12. Lunch, snacks, books and most clubs are included.
