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
Traill International School follows the British National Curriculum from Early Years through Sixth Form. In Kindergarten, children follow the EYFS framework, focusing on key developmental areas through structured play and thematic learning. Primary students (Years 1–6) study core subjects including English, maths, science, and computing, alongside languages, art, and PE, with progress tracked using Rising Stars assessments. The Middle Years programme (Years 5–7) bridges Primary and Secondary, combining subject specialisation with continued development of foundational skills. In Secondary, students follow Key Stage 3 in Years 7–9, before beginning the two-year Cambridge IGCSE programme in Years 10–11, typically taking 9–10 subjects. Sixth Form students can choose either the Cambridge A-Level programme or the Traill Diploma, a coursework-based alternative focused on personal interests and future plans.
