Academic and sporting excellence followed suit. Traill International School pioneered the introduction of British O Levels and A Levels in Thailand, and later became the computer examination centre for London University. The Traill family, who played a pivotal role in shaping nearly 6 decades of academic excellence, continues to be actively involved as Governors and Directors.

Throughout the years, Traill International School has expanded and flourished. New, thoughtfully designed buildings and state-of-the-art facilities have enhanced the learning environment. While staying true to the founding ideals of Mr. and Mrs. Traill, the school remains committed to continuous improvement. It adapts its curriculum and facilities to align with 21st-century standards and values.

Despite the passage of time, Traill International School maintains its hallmark characteristics: a caring, happy, and secure environment. It remains an ideal place for student development, regardless of the era. For almost 60 years, Traill has continued to demonstrate that happy and confident students not only excel academically but also grow into well-rounded individuals—achieving gold standard qualifications that open doors to the world’s best universities.
