King's College International School Bangkok (King's Bangkok)

Established in 2020 as an overseas campus of the renowned King's College School Wimbledon, the Bangkok school follows the English National Curriculum with IGCSE and A-Level pathways. The campus features substantial facilities including an Olympic-sized swimming pool, 600-seater auditorium, gymnasium with three basketball courts, and dedicated Early Years Centre with specialized play areas. Located on Ratchadaphisek-Rama III Road, the school serves both expatriate families and local Thai students seeking British education, with Mandarin instruction as a distinctive curriculum feature not offered at the UK parent school.

Under founding principal Thomas Banyard, who previously led King's College campuses in both Wimbledon and Hangzhou, the school aims to replicate the academic standards that made the UK school a top performer in London rankings. The partnership with Thailand's Saha Group provides local operational support while maintaining King's College educational standards. However, the school's location approximately 10km from Bangkok's city center requires significant commuting time in the capital's notorious traffic, potentially limiting appeal for families living in central areas compared to more accessible international schools.
