The International Baccalaureate (IB) is a globally recognised education program that provides an alternative to local high school curriculums like VCE or HSC. Offered in over 150 countries, including Australia, IB is designed to develop well-rounded students who can thrive in a globalised world.
Students who complete the IB Diploma Programme (IBDP) in Year 12 receive a final IB score out of 45, which is then converted to a notional ATAR for Australian university admissions.
How Does IB Work in Australia?
Some schools in Australia offer IB exclusively, while others provide it as an alternative for Years 11 and 12. IB is divided into four different programs, but the IB Diploma Programme (IBDP) is the most relevant for students in senior secondary school.
IB vs. ATAR: Key Differences
The IB Diploma Programme differs significantly from standard Australian high school curriculums. Instead of selecting a limited number of subjects, IB students study six subjects across various disciplines and complete three core components:
- Theory of Knowledge (TOK) – A critical thinking and reflection subject.
- Extended Essay (EE) – An independent research project (4,000 words).
- Creativity, Activity, Service (CAS) – Personal development through extracurricular involvement.
How is IB Scored?
Each IB subject is graded from 1 to 7, with a total possible score of 42 points. The TOK, EE, and CAS components contribute up to an additional 3 points, bringing the maximum IB score to 45.
This score is then converted into a notional ATAR to align with the Australian ranking system. For example:
- IB 45 → ATAR 99.95
- IB 40 → ATAR 96.60
- IB 30 → ATAR 81.45
- IB 24 (Pass Mark) → ATAR 67.35
