Students study English language as well as literature, Mathematics and Science based on the UK curriculum. Research skills and inquiry learning are developed through Humanities. All students take Computer Science and Digital Literacy, Physical Education, Art and a second language and PSHEE (Personal, Social, Health and Economic education). Non-Thai students must study Thai as a foreign language.
At the end of Year 9, students write the Cambridge Checkpoint exam for Key Stage 3 in Mathematics and Science, and English for First Language English speakers. Second Language English speakers write the Cambridge ESOL First Certificate in English.

Specific targets are set for students by their subject teachers and all students are encouraged to aim for progression through levels in order to work to the best of their ability.
