The International Baccalaureate (IB) Diploma is a globally recognised qualification for students aged 16–19. Offered in over 140 countries, including a growing number of UK boarding schools, the IB provides a broad and rigorous academic education that prepares students exceptionally well for university and life beyond.

What is the IB Diploma?

The IB Diploma Programme spans two years and requires students to study six subjects across a range of disciplines:
  • Language and Literature
  • Language Acquisition
  • Individuals and Societies
  • Sciences
  • Mathematics
  • The Arts (or an additional subject from the other groups)
Students take three subjects at Higher Level (HL) and three at Standard Level (SL), ensuring both depth and breadth of study.
Alongside their academic subjects, students complete three core components:
  • Theory of Knowledge (TOK) – exploring how we know what we know
  • Extended Essay (EE) – a 4,000-word independent research paper
  • Creativity, Activity, Service (CAS) – experiential learning through personal development projects

Why Choose the IB?

The IB is ideal for academically strong, well-rounded students who enjoy a broad curriculum and are ready for a challenge. Key benefits include:
  • Development of independent research, time management, and critical thinking skills
  • Greater cultural awareness and global perspective through language study and CAS
  • Strong preparation for university—IB students are highly sought-after and three times more likely to enrol at top global universities
  • Equivalent to 5 A-Levels in UCAS points
The IB appeals to students who want to keep their academic options open while gaining skills that are relevant across disciplines and careers.

Entry Requirements

To succeed in the IB, students should be motivated, organised, and academically capable. We recommend:
  • Minimum grade 5 at GCSE (or equivalent) in chosen subjects
  • Grade 8–9 for HL Mathematics, 7 for HL Sciences, and 6+ for other HL subjects
  • A strong work ethic and willingness to engage fully in the demands of the programme
