Curriculum details
Curriculum details
Heathfield International School follows the English National Curriculum from Early Years through Sixth Form, offering a clear progression from EYFS in Nursery and Reception to IGCSEs and A Levels. In Early Years, the focus is on foundational skills through play-based and thematic learning. The Primary School (Years 1–6) delivers a broad curriculum including English, mathematics, science, humanities, technology, and the arts. In Secondary (Years 7–9), students deepen their subject knowledge before progressing to the Cambridge IGCSE programme in Years 10–11. Sixth Form students (Years 12–13) choose from a range of Cambridge A Level subjects to prepare for university entrance. A varied co-curricular programme, including options like Robotics, Coding, French, Taekwondo, and Cooking, complements the academic curriculum.
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.
