International Baccalaureate (IB): A parent's guide

The IB is an inquiry-driven international curriculum offered in three stages: PYP (ages 3–12), MYP (ages 11–16) and the Diploma Programme (ages 16–19). It's the closest thing the international-school world has to a global default — accepted by universities in every major destination, and consistent enough that families moving between IB schools rarely have to bridge gaps.

Who the IB suits

Families relocating internationally — especially those who expect to move again — benefit most because IB transcripts and grading translate cleanly between countries. The Diploma in particular is well-recognised by universities in the UK, US, Australia, Singapore, the Netherlands and beyond. Students who enjoy writing, research and connecting subjects tend to do best; the Extended Essay and Theory of Knowledge components are non-trivial.

What it looks like in practice

IB Diploma students take six subjects (three at Higher Level, three at Standard Level), plus the three "core" components: Extended Essay, Theory of Knowledge and Creativity, Activity, Service (CAS). It's known for breadth — even sciences students take a language, and humanities students take a maths course. That's a strength if your child is well-rounded, a stretch if they're already heavily specialised.

How it compares to British and American systems

Against A-Levels: IB is broader (six subjects vs three), more demanding outside class (essays, CAS hours), and arguably better for keeping options open at university. Against the American high-school diploma + AP: IB is more structured and prescriptive; AP is more modular and lets students pick their depth. Schools often offer one or the other but a handful run both side-by-side.

FAQs about the IB curriculum

Is the IB harder than A-Levels or AP?

IB is broader and more workload-heavy than A-Levels, partly because of the core components (Extended Essay, ToK, CAS). It's comparable in academic depth at Higher Level. AP is more flexible — students choose how many courses to take.

Do UK universities accept the IB Diploma?

Yes — UK universities including Oxford, Cambridge and the Russell Group accept the IB Diploma. Typical offers are quoted in IB points (e.g. 38 points overall with specific Higher Level scores).

At what age can my child start IB?

The Primary Years Programme (PYP) starts at age 3. Many international schools begin the full IB pathway in early years and continue through to the Diploma Programme at 16–19.

Can my child switch into IB mid-school?

PYP and MYP are flexible enough to absorb mid-year arrivals. The Diploma Programme is harder to join after the first term of Y12 because the two-year programme builds cumulatively. Speak to admissions about bridging options.
