IB or A-Level: Which Is Right for Your Child?

By Laura Harrison, 27 October 2026

For students at international schools, and some in the UK, the choice after GCSE or IGCSE is between A-Levels and the International Baccalaureate (IB) Diploma. Both are respected by universities around the world. They suit different students.

A-Levels: depth in a few subjects

Students usually take three subjects (sometimes four) and study them in real depth. A-Levels suit students who already know what they enjoy, or who want to specialise early, for example in sciences or maths for a related degree.

The IB Diploma: breadth and balance

IB students take six subjects, three at Higher Level and three at Standard Level, across languages, humanities, sciences and maths. They also complete the Extended Essay, Theory of Knowledge and CAS (creativity, activity, service). The IB suits students who like variety and are well organised.

Questions to ask

  • Does my child prefer going deep in a few subjects, or keeping many going?
  • How do they handle coursework and deadlines alongside exams?
  • Do the universities and courses they are considering ask for particular subjects?
  • Which does their school offer, and how well?

Support for either route

Both routes step up sharply from GCSE and IGCSE. A qualified teacher who knows the specific course can help with difficult topics, coursework or internal assessments within the rules, and exam technique.
