Here’s something most families don’t stop to consider: how well your child performs in Year 12 is driven far more by the curriculum they’re studying than by the school they attend. Even a genuinely excellent student, at a genuinely excellent school, will likely underperform if the curriculum’s structure doesn’t suit how they work.

If your child is at a school offering the IB Diploma, this is worth sitting with for a moment. Choosing that school back in Year 7 or 8 made complete sense — it was likely the strongest academic option available, IB was (and still is) marketed as the “gold standard,” and a curriculum decision felt years away. But your child today may look quite different to the child you enrolled. It’s worth periodically asking: based on who they are now, not who we expected them to be, is this still the best-fit curriculum?

This isn’t an anti-IB post. The IB is a genuinely excellent curriculum — for the right student. It’s a post about making sure the curriculum decision gets made on its own merits, deliberately, rather than by default because it’s the option your school happens to offer.

Why so many families never actually choose

For many private school families, the path into IB isn’t really a choice at all — it’s an inheritance. The local curriculum feels too easy, too narrow, or not internationally recognised enough for a child with big ambitions, and the school only offers one “serious” alternative. So IB becomes the default, not because it was chosen on its merits against other options, but because it was the only door open.

What often isn’t discussed is that the IB is one internationally recognised curriculum, not the only one. International A-Levels are just as globally respected, just as valued by top universities, and structured in a fundamentally different way — one that suits a different kind of learner. Families rarely get to weigh the two side by side, because most schools only offer one.

The alternative most Australian families haven’t considered

International A-Levels — across all awarding bodies, including Cambridge International, Pearson Edexcel, and others — are, in fact, the most commonly taken qualification among international schools worldwide, ahead of the IB Diploma. It’s simply less visible in Australia because so few local schools have offered it — until recently.

That’s starting to change. PLC Sydney, one of the country’s most respected girls’ schools, introduced Cambridge International A-Levels in 2025 as an alternative to the HSC in Years 11 and 12 — one visible example of a broader shift already well underway internationally. As more Australian schools begin offering an A-Level pathway (through Cambridge, Pearson Edexcel, or otherwise) over the next few years, A-Levels are likely to become a far more familiar option for local families — not a lesser-known substitute, but the world’s leading pathway that Australia is only now catching up to.

Crucially, A-Levels don’t close any doors. They’re a direct entry pathway into Australian, UK, and US universities alike, and the subject-specific depth they provide is widely considered excellent preparation for degree-level study — students arrive at university having already worked at a level of depth closer to what their course will demand. Choosing A-Levels over the IB isn’t a trade-off against university options; it’s simply a different (and, for many students, better-fitting) route to the same destinations.

What the IB actually asks of a student

Before assuming the school-chosen default is still the right fit, it’s worth understanding exactly what two years of the IB involves:

1. It’s six subjects, not two or three. Every IB student studies across six subject groups simultaneously — languages, humanities, sciences, maths, and the arts — for the full two years. There’s no narrowing down to your strengths.

2. There’s no escaping your weaker subjects. A student who is brilliant at maths and physics still has to carry a language, a humanities subject, and an arts/elective choice all the way to final exams. Weaker subjects don’t disappear; they sit alongside the strong ones for two years straight.

3. The Extended Essay is a serious undertaking. A ~4,000-word independent research essay, on top of six subjects’ worth of coursework and internal assessments, run in parallel with everything else.

4. Theory of Knowledge (TOK) is compulsory. Not every student enjoys — or does well in — abstract, philosophical reflection on the nature of knowledge itself. It’s assessed, and it counts toward the final score.

5. CAS isn’t optional extracurriculars — it’s part of the qualification. Creativity, Activity, Service hours have to be logged, reflected on, and signed off. For students already stretched thin, it’s another deadline-driven commitment, not a break from academics.

6. It’s a two-year lifestyle, not a two-year subject list. Because of the breadth, the EE, TOK, and CAS running concurrently, IB students are rarely “off.” Coursework, reflection, and logging are continuous rather than concentrated around exams.

7. Grades can be pulled down by a subject your child never wanted to take. Because IB scores are compensatory (averaged across all six subjects), a student who is exceptional in three subjects but merely average in the other three will get an overall score that reflects the average — not their strengths.

8. Universities value the IB — but they value A-Levels just as highly. For university pathways where a student already knows their intended field (engineering, medicine, law, business), a strong set of 3–4 A-Levels is viewed by UK, Australian, and US institutions as an equally serious, equally rigorous qualification — and very strong preparation for the depth of study those degrees demand.

9. Specialisation earlier isn’t a weakness — for the right student, it’s an advantage. A student who already knows they want to pursue engineering doesn’t need to also carry a language and an arts subject to be taken seriously by universities. A-Levels let them go deep in fewer subjects instead of wide across six.

10. “Regret” usually isn’t about the IB being a bad curriculum — it’s about fit. The students who struggle most with the IB are rarely underachievers. They’re often high-performing, focused students who knew their strengths early, and found the mandatory breadth, the EE, TOK, and CAS to be a drag on a profile that was already strong.

5 signs your child might be a better fit for A-Levels

1. They already know what they’re good at — and want to focus on it. Rather than feeling anxious about narrowing down too early, they’re relieved at the idea of dropping subjects they don’t enjoy.
2. They’ve never felt drawn to the “extras.” The idea of an extended independent research essay, a philosophy-style course like TOK, or logging service and creativity hours feels like an obligation, not an opportunity.
3. They perform strongly in some subjects and only adequately in others — and that gap worries you. Under a compensatory scoring system, a weaker subject can quietly drag down an otherwise excellent result.
4. They want their life outside academics to be their own. Elite sport, music, a part-time job, or another serious commitment doesn’t need to be folded into (and assessed as part of) their qualification.
5. They want exam-focused, in-depth study rather than continuous, multi-component assessment. They’d rather prepare deeply for a smaller number of final exams than juggle ongoing coursework, reflections, and logs across six subjects for two years straight.

IB vs A-Levels: the fit at a glance

Revisit the decision on its merits, not on inertia

The school you chose in Year 7 was the right decision at the time, made with the information and the child you had in front of you then. But a curriculum decision isn’t a one-time inheritance from a school enrolment — it’s a choice that deserves to be revisited on its own terms as your child’s strengths, interests, and working style become clearer.

If your child already knows their strengths, prefers depth over breadth, and would rather commit fully to three or four subjects than carry six for two years — that’s worth acting on now, before Year 11 locks the decision in, not after.
