The Chalfonts Independent Grammar School is a fully accredited International Baccalaureate (IB) World School offering the IB Diploma Programme (DP).

The IB DP aims to develop students who have excellent breadth and depth of knowledge – students who flourish physically, intellectually, emotionally and ethically.

It is an Ofqual recognised alternative to A-Levels, with a broader number of subjects making it a favourite of Admissions Officers at top Universities around the world.


IB Diploma students:

  • Are more than twice as likely to enrol at one of the UK’s top 20 universities.
  • Are nearly twice as likely to succeed in application for courses in Medicine and Dentistry.
  • Are significantly less likely to drop out of university courses.
  • Are 30% more likely to a gain first-class honours degree.
  • Are twice as likely to continue with further study after the first degree.
  • Have significantly higher starting salary, after university.

Students choose courses from the following subject groups: studies in language and literature; language acquisition; individuals and societies; sciences; mathematics; and the arts.

Students may opt to study an additional science, individuals and societies, or language course, instead of a course in the arts.

Students will take some subjects at higher level (HL) and some at standard level (SL). HL and SL courses differ in scope but are measured according to the same grade descriptors, with students expected to demonstrate a greater body of knowledge, understanding and skills at higher level.

The IB Diploma consists of the following elements:

  • Group 1: Studies in Language and Literature.
  • Group 2: Language Acquisition.
  • Group 3: Individuals and Societies.
  • Group 4: Experimental Sciences.
  • Group 5: Mathematics.
  • Group 6: The Arts.
  • Creativity, Activity, Service (CAS)
  • Extended Essay (EE)
