Curriculum details
Astra Academy delivers the UK National Curriculum from Year 1 through Year 13. In the primary years, students experience broad learning across literacy, numeracy, science, and creative subjects. The approach is inquiry-driven, with a focus on helping students understand how to think critically and communicate clearly. In secondary school, students follow Key Stage 3 in Years 7 to 9, then prepare for Cambridge IGCSEs in Years 10 and 11. In Years 12 and 13, students work toward Cambridge A-Level qualifications. The school uses a structured progression model that builds academic depth and skill development across each stage, preparing students for university-level expectations.
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.
The school does not have publicly available information on their Social and Emotional Learning.
Social & emotional learning
RBIS references SEL mainly through its pastoral care framework and its Nurture Group, a small, specialized class that targets both academic and social‑emotional development for learners struggling to access the curriculum. The school also uses Behaviour Support Plans (BSPs) with clear goals and strategies to promote positive behavior. Its well-being pages describe a threefold focus on pastoral care, personalized learning and student well‑being.
Special educational needs (SEN)
Special educational needs (SEN)
The school does not have any dedicated SEN support.
Special educational needs (SEN)
RBIS states that families can consult the school SENCo; provision can include IEPs (Individual Education Plans), BSPs, teaching assistant support, and the Nurture Group for students who need a modified pace and environment. The Thai-language SEN page adds that support may involve curriculum/teaching adjustments, health‑professional advice, and peer-circle arrangements; needs are reviewed to ensure support is “adequate and effective.” The site does not describe RBIS as a specialist SEN school; it presents SEN provision within a mainstream international school setting.
English as an additional language

The school offers EAL.
English as an additional language
RBIS runs an EAL programme and places students using internal English assessments aligned to CEFR levels. Students close to CEFR B1 join mainstream lessons with targeted in‑class language support; those below B1 may enter the English Language Centre (ELC) for more intensive provision before progressively transitioning to full timetables. The site notes that all teachers are qualified specialists and classes are small, enabling individual attention.
Mental wellbeing
Mental wellbeing
Astra has a weekly timetabled Wellbeing lesson across all year groups, where students learn to recognize and express emotions constructively and build resilience. Additionally, the school’s Safeguarding policy promotes restorative conflict resolution, emotional awareness, and openness in addressing student concerns.
Mental wellbeing
RBIS publishes a well‑being page stating that student well‑being is embedded alongside pastoral care and personalized learning. The page defines well‑being and positions it as a core part of school life, but does not name a counselling team, referral pathway, or formal mental‑health programme. Broader pastoral statements reiterate individualized attention and student well‑being as a core strand.

The school promotes restorative conflict resolution through its Wellbeing program, encouraging students to understand their emotions and communicate effectively. Astra’s medium size fosters close relationships among staff and students, making it easier to detect and respond to issues early and maintain a safe, supportive environment.
Safeguarding
RBIS International School has a comprehensive safeguarding policy covering all students, overseen by Designated Safeguarding Leads and a board representative. The policy outlines clear procedures for reporting and responding to concerns, including escalation to local authorities if necessary. All staff undergo regular safeguarding training and follow strict codes of conduct, with safer recruitment practices in place. Students are supported through PSHEE lessons, online safety education, and anti-bullying initiatives. The policy is reviewed annually by the school’s Board of Management.
