International School Bangkok’s first day of classes was held on May 14, 1951 (it was then called the International Children’s Center), thus May 14, 2026 will be what could be called ISB’s 75th birthday. On that day the school will be starting a series of 75th Anniversary events with a program that will be held on campus for the entire student body.
Another event that will be held before the end of the 2025-2026 school year is a 75th Anniversary Charity Concert. The event, which will be held on June 7th, is called “Harmony for Hope” and has a goal of collecting enough money to support 75 worthy Thai students to complete their four-year high school diploma. Of note, ISB already has some amazing performers lined up for the concert with Thai R&B queen, ISB alumna Lydia Deane, lined up to be the star attraction.
Additionally, a large alumni 75th Anniversary reunion event has been confirmed for January 21-24, 2027. Details are being organized, but keep those days open as it should be an amazing celebration of ISB’s 75 years.
