Founded 1951, one of Southeast Asia's most prestigious international schools offering US curriculum with IB and AP options.
International School Bangkok (ISB) first opened its doors in 1951 as the International Children's Center on the grounds of the U.S. Embassy Bangkok, making it the first international school established in Thailand and one of the oldest in Southeast Asia. For over 70 years, ISB has maintained its reputation as a premier educational institution, currently serving approximately 1,700-1,800 students from over 60 nationalities on a beautiful 37-acre campus in the Nichada Thani community of Nonthaburi Province. ISB offers an accredited US international curriculum from Pre-K through Grade 12, with students earning a U.S. high school diploma upon graduation. The school was the first in Thailand to offer the International Baccalaureate (IB) Diploma Programme, and today students in grades 11-12 can choose to pursue the IB Diploma alongside or instead of the standard US diploma. Additionally, ISB offers Advanced Placement (AP) courses, providing multiple pathways for academic excellence. The school is fully accredited by the Western Association of Schools and Colleges (WASC), ensuring programs meet rigorous US educational standards. ISB's outstanding facilities include two swimming pools, two sets of tennis courts, two theaters, a state-of-the-art invention center, advanced robotics programs, and comprehensive sports and arts facilities. The school is located within the secure Nichada Thani gated community, creating a safe, family-friendly environment.

"Our kids have been at ISB for 7 years and we could not be any happier. ISB's teachers and facilities are the best in Bangkok. The IB Program is excellent and really helped our oldest make their first year at university more manageable. The invention center and robotics programs are truly world-class."
