The UK Education System Explained
The UK education system has its own structure, stages and qualifications that can be unfamiliar to international families. Understanding how it fits together — from primary school to university entry — helps you choose the right entry point for your child.
Stages of UK education
Education is broadly split into primary school (roughly ages 5–11) and secondary school (ages 11–16), followed by sixth form or college (ages 16–18). Independent and boarding schools may use slightly different year-group names but follow the same overall progression.
Key qualifications: GCSEs, A-Levels and the IB
At around age 16, students take GCSEs (or IGCSEs internationally). From 16 to 18, most study A-Levels — typically three subjects studied in depth — while some schools offer the International Baccalaureate (IB) Diploma, a broader programme recognised worldwide.
These qualifications are the main route into UK universities, and the subjects chosen at this stage shape which degrees a student can apply for.
The route to university
Students apply to university through UCAS, usually in their final year of sixth form, using their predicted or achieved A-Level/IB results. International students who need to bridge a gap can take a foundation or pathway course before starting a degree.
