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
RBIS follows the English National Curriculum from Early Years Foundation Stage (ages 18 months–5) through to Upper Secondary (ages 16–18) with distinct Key Stages 1–5 . At Key Stage 3 (Years 7–9), students study a broad range of subjects as a foundation before moving into the pre‑IGCSE Year 9 programme . In Key Stage 4 (Years 10–11), students take Cambridge IGCSE subjects across core and elective options, including English, Maths, Sciences, Humanities, Thai (for Thai nationals), and Mandarin for non-native speakers . Post‑16 (Years 12–13, Key Stage 5), students choose between Cambridge A‑Levels, BTEC qualifications, or an RBIS High School Diploma, with support for IELTS/SAT testing if required.
These varied pathways offer both academic and vocational routes leading to university entry in Thailand and abroad.

Submit the application and documents Applications can be submitted by email to the admissions team. Required documents include a completed application form, a copy of the child’s passport and visa, previous school reports, and a student health certificate.
Assessment and interview For Year 3 and above, students are required to take a CAT4 cognitive abilities test, an English proficiency test, and may attend a formal interview. Younger children are assessed more informally through play and observation.
