In 2006, during Brother Sakda Kitcharoen’ s term governance, the ACSP English Program (EP) was introduced to serve students with an excellent academic program.

Initially, the program had only three classes: Prathom 1, Prathom 4 and Matthayom 1, with five foreign teachers and six Thai teachers. Each following year, the program kept growing until all 24 classes were full, six years later. Currently, there are over 664 students, 33 foreign teachers and 31 Thai teachers.
