Welcome to ICSUD!

International Community School (ICS) was founded in 1993 in Bangkok as a non-profit Christian international school and has been the leading American AP K-12 institute for the past many years. Due to our continued success, a new campus was opened in Udon Thani in 2020. ICS is known for the close-knit community fostered between its faculty, students, and parents. This comes from a relentless focus on care and individual attention in order to help each child thrive in the classroom. The emphasis on character formation together with student achievement is why ICS is one of the very few international schools with continual growth over the past 32 years in Bangkok and now in the city of Udon Thani over the past 5 years.
