Curriculum details
Curriculum details
Aster International School offers a British-style curriculum with an emphasis on real-world learning and student engagement. The early years program is based on the Early Years Foundation Stage (EYFS) and focuses on communication, personal development, and basic skills through play.
In primary and lower secondary, Aster blends the English National Curriculum with project-based learning. Students explore core subjects like English, math, and science through interdisciplinary projects that also incorporate art, languages, and physical education. Specialist subjects include Mandarin, French, and Thai, with lessons adapted to student needs.
In the upper secondary years, students prepare for IGCSEs and A-Level examinations while also having the option to complete a high school diploma. Instruction becomes more focused on subject specialization, and students are encouraged to develop academic responsibility. Outside the classroom, Aster supports learning through enrichment clubs, sports, language classes, and Thai cultural activities.
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.
