Curriculum details
Curriculum details
The Australian International School Bangkok (AISB) follows a pathway that combines the Australian Curriculum and the Cambridge International programme. In the Primary Years (Foundation to Year 6), the school uses Australian teaching approaches with a broad curriculum including English, Mathematics, Science, Humanities, Languages, the Arts, and Physical Education. In Lower Secondary (Years 7–8), students continue with the Australian Curriculum while also preparing through Cambridge Lower Secondary courses. In Middle Secondary (Years 9–10), students work towards the Cambridge IGCSE qualifications, which cover a wide range of academic subjects. The final stage, Senior Secondary (Years 11–12), offers the Cambridge AS and A Levels, providing internationally recognised qualifications for university entrance. Throughout all year levels, students also study Thai language and culture, with additional options in French, Mandarin, Japanese, and German for native speakers.
Curriculum details
Sukhumvit 107 uses a combination of the English National Curriculum (EY to Key Stage 3) and progression into IGCSE (Years 10–11) followed by the International Baccalaureate Diploma or Career-related Programme (Years 12–13). In Early Years, the school follows UK EYFS with a play-based, child-centred approach. In Primary, students study core subjects and humanities as part of an inquiry-based model aligned to British curriculum standards.
In Secondary, Key Stage 3 (Years 7–9) continues with the British curriculum, enhanced by additional subjects including languages, arts, and technology. In Key Stage 4, students prepare for IGCSE exams, choosing from a broad range of academic and vocational subjects. For Sixth Form (Years 12–13), students pursue either the IB Diploma Programme (IBDP) or IB Career-related Programme (IBCP). Some students may also study BTEC or ASDAN courses as alternative qualifications, especially for personal development and skills-based learning.
