English is the language of instruction with an English as a Second Language (ESL) program to support students joining mainstream education. Thai language and culture is taught in two tracks: a Thai Language, Culture and History programme for native Thai speakers aligned to the Thai MOE curriculum, and a Thai Language, Culture and History programme for non-native speakers offered from KG1 to Year 9; non-native speakers may join the native speakers' class if eligible, and students progress to Year 11 for iGCSE First Language Thai. The curriculum also includes specialist language teaching in Mandarin, Japanese, French and Thai Language and Culture (with intercultural studies in Key Stage 2 covering Japanese, Mandarin and French).
Two immersion classes exist within Key Stage 3 for beginners up to lower intermediate. In these classes, students attend mainstream Art, P.E. and Games while the remainder of the time is spent in the ESL classroom, where English, Mathematics and Science are taught by ESL specialists; Information Communication Technology, Geography, History and General Studies are taught informally to support language acquisition. ESL Class 3 is a partial immersion class in which students attend mainstream Drama, Music, Mathematics, ICT, Art, P.E. and Games, with the remainder of the time spent in the ESL classroom for History, Geography, General Studies and ESL Science.
