What is the IB? A Complete Guide to the International Baccalaureate

If you’ve ever wondered why so many students and parents choose the IB, you’re not alone. It’s a program that has gained worldwide respect for its focus on developing both academic skills and personal growth. In this guide, we’ll explore what the IB involves, how it works, and why it might be the right choice for you or your child.

What is the IB?

The International Baccalaureate (IB) is a globally recognised educational framework designed to develop well-rounded, independent learners who are prepared for both university and life beyond the classroom.

Founded in 1968, the IB offers a consistent curriculum used in more than 5,700 schools across over 160 countries. Its mission goes beyond academics — it’s about fostering critical thinking, intercultural understanding, and a lifelong love of learning.

In Australia, the IB is offered by select independent and government schools, and is an alternative to state-based senior certificates like the VCE (Victoria), HSC (NSW) or QCE (Queensland).

The Four IB Programmes

The IB isn’t just for senior students - it offers four distinct programmes catering to different age groups and you might find that your local Primary or High School actively markets that it follows the IB program:

Primary Years Programme (PYP): For students aged 3–12, focusing on inquiry-based learning and developing foundational skills.
Middle Years Programme (MYP): For students aged 11–16, building academic breadth alongside personal, social, and emotional development.
Diploma Programme (DP): For students aged 16–19, a challenging two-year course recognised for university entry worldwide.
Career-related Programme (CP): For students aged 16–19, combining academic study with career-focused learning.

In Australia, the IB Diploma Programme (IBDP) is the most well-known, and it’s what people often mean when they talk about “doing the IB” in Years 11 and 12.

The IB Diploma Programme Structure

The IB Diploma is designed to challenge students academically while also encouraging personal growth. Students study six subjects — three at Higher Level (HL) and three at Standard Level (SL) — across different disciplines:

Studies in language and literature (e.g., English)
Language acquisition (e.g., French, Spanish, Mandarin)
Individuals and societies (e.g., Economics, History, Psychology)
Sciences (e.g., Biology, Chemistry, Physics)
Mathematics (e.g., Analysis & Approaches, Applications & Interpretation)
The arts (e.g., Visual Arts, Theatre, Music) or a second subject from the above categories

Alongside these subjects, students complete three core components that set the IB apart:

Theory of Knowledge (TOK): An exploration of how we know what we know, encouraging critical thinking across disciplines.
Extended Essay (EE): A 4,000-word independent research project on a topic of the student’s choice.
Creativity, Activity, Service (CAS): Engagement in creative projects, physical activities, and community service.

How the IB is Assessed

IB assessment combines internal and external evaluations.

External assessments include written exams at the end of the two-year programme, which are marked by international examiners.
Internal assessments are marked by teachers and then moderated externally, covering projects, essays, oral presentations, and practical work.

Each subject is graded on a scale of 1 to 7, with up to 3 extra points available from TOK and the EE, for a maximum score of 45 points.

In Australia, IB scores can be converted to an ATAR equivalent, which universities use for admissions (ie. to compare IB students to students who sat the VCE, HSC, QCE, WACE or other State curriculums). For example:

IB 45 → ATAR 99.95
IB 40 → ATAR 96.60
IB 30 → ATAR 81.45
IB 24 (Pass Mark) → ATAR 67.35

Why Choose the IB?

The IB Diploma isn’t for everyone - it’s academically rigorous and requires strong time management - but it offers unique benefits:

Global recognition: Accepted by leading universities in Australia and overseas.
Breadth of study: Students keep a balance of subjects rather than specialising too early.
Skills for life: Research, essay writing, presentation, and analytical skills are built into the programme.
Focus on personal growth: CAS activities encourage students to look beyond grades and contribute meaningfully to their communities.

Challenges to Consider

While the IB can be rewarding, it comes with challenges:

Heavy workload: Six subjects plus the core components can be intense.
Time pressure: Effective organisation is essential to balance assessments, CAS commitments, and exam prep.
High expectations: The IB demands academic consistency over two years, not just last-minute exam preparation.
