The school was located on Soi Prong Jai in the Sathorn area of Bangkok and welcomed 120 students into kindergarten through eighth grade when it opened in August 1993.

The ICS Educational Foundation Board, with the cooperation of the families of ICS, purchased the current 16.2 rai (6.4 acres) of land in Bang Na and began building in 2003. International Community School opened the Bang Na campus in September 2004 with nearly 500 students in four year-old kindergarten through twelfth grade.

Superintendent Darren Gentry has retired from his position at the end of the 2020-2021 school year, leading to a shift in leadership and structure.
