In Brief
Traill International School is a well-established British curriculum school founded in 1966, serving nearly 400 students from over 26 nationalities in central Bangkok. While it maintains strong academic results with 100% A Level pass rates and offers a close-knit community feel, the school commands premium fees and generates minimal discussion among Bangkok's international teaching community.
Operating from Bang Kapi district for over 55 years, Traill follows the National Curriculum for England from kindergarten through A Levels under Head Teacher Gordon Espley-Jones' leadership. The school deliberately maintains a boutique model with under 400 students representing more than 26 nationalities, creating an intimate educational environment where individual attention is possible. Teachers are recruited internationally from the UK, US, Canada, Australia, and South Africa, providing diverse educational perspectives within the British framework.
Academic performance shows solid results with 76% IGCSE pass rates, 89% AS Level success, and notably 100% A Level achievement. The curriculum includes standard British subjects enhanced with international elements through Thai language instruction and optional French, Mandarin, and Japanese studies. Students can pursue IGCSEs and A Levels, though the school does not offer IB programmes. Despite charging among Bangkok's highest international school fees, Traill positions itself as providing value-for-money education through its personalized approach and strong examination outcomes.
