About D-Prep

D-PREP is a Nursery-Grade 12, IB system international school in Bangkok that follows an international curriculum. We are a multilingual school with the primary language of instruction being in English followed by Thai and Chinese.

Our belief is that happiness and success has to happen hand in hand for every single child. We believe in a well-rounded and balanced approach to education where the child is viewed as a capable learner with ability to lead most of his or her own learning through the guidance and support of coaches (teachers). We take the best current educational practices from around the world to form and constantly improve on our own approach to education such as the Reggio Emilia method from Italy and the Finnish teaching pedagogy. 

D-PREP is affiliated with The American School of Bangkok which opened the first international kindergarten Thailand as Didyasarin International Kindergarten since 1983 and changed to Didyasarin International School in 1995 as it expanded from a kindergarten to a full K-12 school. The final change took place when the school adopted a fully American curriculum under the name The American School of Bangkok in 1997. ASB now has two K-12 campuses in Sukhumvit and Green Valley, Bangna. ASB is proud to have graduated several hundred students who have since attended several top universities around the world such as Yale University, New York University, UCLA, Harvard University, to name a few.
