International School Bangkok
"International School Bangkok (ISB) stands as one of Thailand's most established and respected international schools, offering a rigorous, English-language education to students from prekindergarten through grade twelve."
With a mission rooted in academic excellence and the development of globally minded young people, ISB has long been a trusted destination for expatriate families and relocating professionals seeking a world-class schooling experience in Southeast Asia. Founded in 1951, ISB carries with it more than seven decades of educational history in Thailand, making it one of the oldest international schools in the country. That depth of experience is reflected in the confidence with which the school serves its diverse community, drawing students from across the globe and providing a stable, nurturing environment for children who may be navigating the challenges of an international move. Academically, ISB follows an American-style curriculum throughout its PK–12 program, providing students with a familiar and well-structured educational framework that travels well across borders. At the senior secondary level, ISB offers the International Baccalaureate Diploma Programme, and notably, it holds the distinction of being the first school in Thailand to have introduced the IB Diploma Program — a milestone that speaks to the school's longstanding commitment to educational innovation and global academic standards. The IB Diploma is widely recognized by universities around the world, making ISB an excellent choice for families who anticipate their children pursuing higher education internationally. The school is accredited by the Western Association of Schools and Colleges (WASC), one of the most recognized accreditation bodies in American education. This accreditation provides parents with an important assurance of quality, ensuring that ISB meets rigorous standards in teaching, curriculum, student support, and school governance. ISB is located in the Pak Kret District of Nonthaburi Province, situated within the greater Bangkok Metropolitan Area. While technically just outside Bangkok's city limits, the school is well within reach of the many residential neighborhoods popular with expatriate families. The campus setting offers students a spacious and well-resourced environment in which to learn and grow — a meaningful contrast to the density of the city center, and one that allows for a fuller range of academic and extracurricular programming. What truly sets ISB apart is the combination of its historical roots and its forward-looking academic profile. Few schools in the region can claim both the longevity that ISB has built since 1951 and the distinction of pioneering a globally recognized qualification like the IB Diploma in Thailand. For families arriving in Bangkok from abroad, this translates into a school community that is experienced, confident, and deeply attuned to the needs of internationally mobile students. English is the language of instruction throughout all grade levels, easing the transition for children coming from English-speaking countries or English-medium schools elsewhere in the world. For expatriate families evaluating their options in Bangkok, International School Bangkok offers a compelling blend of proven academic tradition, recognized qualifications, and a genuinely international community — all within one of Asia's most vibrant and dynamic cities.
