Choosing senior subjects: a Year 10 guide for Australian families

If your child is in Year 10, a subject-selection form has probably just landed — and with it, the feeling that you're both deciding the rest of their life over a weekend. You're not. This guide is for parents (and the students themselves) working through Year 11 and 12 subject choices in any Australian state. It explains what these choices actually affect, the few things genuinely worth getting right, and how to keep doors open without trying to plan the whole future at fifteen.

Why it feels bigger than it is

Subject selection usually happens in the middle of Year 10, because the subjects chosen now become the senior certificate your child studies in Years 11 and 12 — the Victorian Certificate of Education (VCE), the Queensland Certificate of Education (QCE), the Higher School Certificate (HSC) in New South Wales, and the equivalents in other states. Those senior results are also what an Australian Tertiary Admission Rank (ATAR) is later calculated from.

So the choice matters — but mostly in one specific way: it can open or close a handful of university courses with subject prerequisites. It does not decide your child's worth, their intelligence, or most of their career. Holding both of those truths at once is the whole job here.

Start with the destination, not the subject list

The single most useful move is to look past the subjects to where they might lead. If there's even a rough idea of a post-school direction, check the prerequisites for those courses early.

Two things make this worth doing now rather than later:

• Prerequisites are published well ahead of time. In Victoria, for example, VTAC (the state's tertiary admissions centre — the body that processes university applications) publishes course prerequisites two years in advance, so a current Year 10 student can already look up the requirements for the year they'll apply. In New South Wales and the ACT, UAC (the equivalent centre there) publishes the same kind of guidance in its Steps to Uni for Year 10 Students booklet.
• They vary and they change. As VTAC notes, prerequisites "can change from year to year," and "courses with exactly the same name at different institutions can have different prerequisite requirements." Queensland's QTAC (that state's equivalent admissions centre) similarly points out that some courses carry prerequisites, some assume prior knowledge, and some only recommend a subject.

It helps to know the difference between three things a course might list:

That first category is the one to protect: missing a true prerequisite can close a specific course no matter how strong the final ATAR is — which is why it's worth a look while choices are still open. A few common patterns (always confirm against the actual course):

• Health and medical sciences often expect chemistry and/or biology.
• Engineering and IT usually expect a higher-level maths, and often physics.
• Commerce and business frequently assume a methods-level maths.

The near-universal two: English, and usually a maths

Across the country, an English subject does most of the heavy lifting — though the exact rule differs by state. In New South Wales, English is compulsory: every HSC student must complete one of four English courses (English Advanced, English Standard, English Studies, or English as an Additional Language or Dialect). In Victoria, qualifying for an ATAR requires at least four senior study scores "including one from the English group." In Queensland, QTAC notes that where a course needs English, it's spelled out in the course entry. A maths subject is the other common assumption, especially for anything quantitative.

Because the rule varies — some states mandate an English subject, others build in a literacy requirement — treat "English, and probably a maths" as the safe starting point and confirm the specifics with your state's certificate authority.

The scaling myth — choose strength and interest

Every year, families agonise over "high-scaling" subjects. Here's the part that gets lost: the admissions centres themselves advise against picking subjects for scaling.

VTAC puts it plainly — "don't choose a subject just because you think it will help your ATAR," because "students typically perform lower in studies they don't like or aren't good at," and that performance gap is usually larger than any scaling bump. QTAC agrees: "it's best not to choose subjects based on predicted scaling outcomes." Choose subjects your child is good at and genuinely interested in — strong results in subjects they enjoy tend to beat mediocre results in a subject picked for its reputation.

STEM, the humanities, or the arts? Choose with purpose, not panic

A balanced selection beats a narrow one chosen out of fear. There's no need to commit to "a STEM kid" — science, technology, engineering and maths — or "a humanities kid" at fifteen. A spread that satisfies common prerequisites and reflects real interests keeps the most doors open while your child works out where they're heading.

It's also worth remembering that an ATAR pathway is one route, not the only one. Vocational Education and Training (VET) subjects, applied/vocational senior options, and school-based apprenticeships are genuine pathways in their own right — not a fallback. Many students mix academic and vocational subjects, and that's a strength, not a compromise.

A simple way through it, as a family

1. Sketch a few possible directions — even broad ones ("something with people", "something hands-on", "not sure yet, keep it open").
2. Check prerequisites for any courses those directions point to, using your state's tertiary admissions centre.
3. Lock in the near-universals — an English subject, and a maths at the right level.
4. Fill the rest with strengths and interests, keeping some breadth.
5. Talk to the school. As QTAC notes, admissions centres don't advise on subject choice — your child's teachers and careers adviser do, and they know your child.
6. Treat it as a draft, not a verdict. Note what can still be changed, and revisit.

Where to get the right information

For anything specific — prerequisites, certificate rules, English requirements — go straight to the source for your state: your state's curriculum or certificate authority, and its tertiary admissions centre (VTAC in Victoria, UAC in NSW and the ACT, QTAC in Queensland, SATAC in SA and the NT, TISC in WA, and the University of Tasmania directly in Tasmania). Your child's school careers adviser is the best guide to how it all applies to them.
