RBIS offers the English National Curriculum from Early Years through IGCSE, with post-16 pathways including A-Levels or BTEC, giving older students a choice between the traditional academic exam route and a more vocationally structured qualification.
The school keeps class sizes small, with Nursery capped at 12 students, and runs a dedicated English as an Additional Language program, which is a specific structural commitment to supporting non-native English speakers rather than treating language support as an informal add-on.
That combination of small capped class sizes and a formal EAL program makes RBIS a particular fit for families whose children are still building English fluency and want dedicated support built into the school's structure from the start.
Families choosing RBIS are typically prioritizing that small-class, EAL-supported environment, alongside the flexibility of an A-Levels or BTEC choice at the post-16 stage.
