How Early Should Your Child Start Selective School Test Preparation?

Another parent at pickup mentions their child has “already started” selective school test preparation, and suddenly you’re wondering whether you’re already behind. It’s one of the first questions that comes up once selective schools enter the conversation, and honestly, there isn’t one neat answer – because Australia doesn’t run a single selective school system. Every state has its own test, its own year level, and its own idea of what counts as early.

There is, though, a useful answer once you know which test your child is actually facing. That’s what this guide is for.

Selective school preparation works best when it’s built around the specific test your state uses, not a generic countdown copied from somewhere else. At NextStepAcademy, we work with families right across this process – from a Year 4 student building reading stamina, through to a Year 8 student in Victoria packing in reasoning practice before the ACER exam. The families who feel calmest on test day are rarely the ones who started earliest. They’re the ones who understood the shape of the test ahead of them, and who timed their selective school test preparation accordingly.

Quick answer: how early should you start?

If you only take one thing from this guide, take this:

• General rule of thumb: begin structured preparation 12 to 18 months before your child’s test date.
• Foundation skills (reading, vocabulary, mental maths) can start earlier and don’t need to feel like exam prep at all.
• Test-format practice is best left until closer to the date, once your child is old enough to actually benefit from it.
• The right timing depends on the test, because NSW, Victoria, WA and Queensland all test at different year levels.

The rest of this guide breaks that down properly, state by state.

Selective school test preparation looks different in every state

This is the part that trips people up, especially if you’ve moved states or picked up advice from a friend whose child sat a completely different test. There’s no single “the selective test” in Australia. Each state runs its own selective or gifted-and-talented pathway, on its own schedule, which means selective school test preparation timelines shift depending on where you live.

NSW runs the largest and most established system by far. The Selective High School Placement Test is sat by Year 6 students and run by the NSW Department of Education, alongside the separate OC Placement Test for Year 4 students chasing a Year 5 place.

Victoria works on a completely different clock. The selective entry high schools exam is sat in Year 8 for Year 9 entry, at one of four schools: Melbourne High, Mac. Robertson Girls’ High School, Nossal High School and Suzanne Cory High School. It’s built and delivered by the Australian Council for Educational Research on behalf of the Victorian Department of Education. Because the intake is Year 9 rather than Year 7, Victorian families usually have a shorter run-up – the process really only kicks off once a child hits Year 8.

Western Australia’s pathway runs through the Academic Selective Entrance Test, or ASET, sat by Year 6 students for entry into Perth Modern School and the wider Gifted and Talented program. The WA Department of Education opens the selection process while students are still in Year 5, with testing itself happening early the following year.

Queensland’s three Queensland Academies (QASMT, QACI and QAHS) run their own entrance assessment process for Year 7 entry, combining a written test with school-based evidence and, in some cases, an interview. Preparation here leans less on pure exam drilling and more on keeping a consistent academic record alongside test familiarity.

Why timing matters so much for selective school test preparation

Here’s the honest reason nobody can give you one universal starting age: these tests aren’t measuring content knowledge the way a spelling test or a maths topic test does. They’re built around reasoning, comprehension under time pressure, and working through unfamiliar problems. That’s true whether it’s called Thinking Skills in NSW, Abstract Reasoning in WA, or the reasoning components of the Victorian ACER paper.

Skills like that don’t respond well to cramming. A child can memorise times tables over a school holiday, but building the stamina to read a dense, unfamiliar passage and answer inference questions accurately in a set number of minutes takes repeated exposure over months. That’s the real case for starting early – and it’s also why families who leave it too late tend to notice it most in the timed sections, not the content itself.

At the same time, starting too early has its own downside. A Year 3 student drilling Year 6-style reasoning questions is more likely to burn out and switch off than gain any real edge, simply because the material isn’t matched to where they are yet. The goal isn’t the earliest possible start. It’s the right start for the test your child is actually sitting.

A realistic selective school test preparation timeline

As a rough guide, most selective school test preparation works best starting 12 to 18 months out from the actual test date, broken into a few loose phases rather than one long stretch of practice.

• Foundation building: Reading widely, building vocabulary, and doing regular mental maths pays off far more here than any workbook – and it doesn’t need to look like exam prep at all. For a NSW family with the Year 6 selective test ahead, this usually falls across Year 4 and early Year 5. For a Victorian family eyeing the Year 8 exam, it’s more realistic in Year 6 and Year 7, since the test itself sits so much later.
• Targeted skill development: This is where your child starts working directly with their specific test format – NSW’s Reading, Mathematical Reasoning, Thinking Skills and Writing sections; WA’s Abstract and Quantitative Reasoning; Victoria’s verbal and numerical reasoning papers. It’s usually the point where families start looking at structured selective school tutoring, since a tutor who knows the exact format can target gaps that general study can’t reach.
• Exam-condition practice: In the final two to three months, the focus shifts to timed, full-length papers under real conditions. This is as much about stamina and pacing as accuracy, since most of these tests put real time pressure on kids who’ve rarely sat anything timed before.

Signs your child needs more time, or less

Not every child needs the full 12 to 18 months of selective school exam preparation, and pushing a confident, fast reader through a needlessly long prep window can do more harm than good. A few things worth watching for:

• If your child already reads well above their year level and stays calm with unfamiliar problems, a shorter, more targeted window closer to the test is often plenty.
• If reading stamina is still developing, or timed conditions tend to rattle them, starting the foundation phase earlier gives that confidence room to build without a looming deadline.
• If your child is juggling something else big in the same year – NAPLAN prep is the common one – it’s worth spacing things out rather than stacking two high-pressure processes on top of each other, especially for NSW families managing both in the same school year. 

Where selective school tutoring fits into your preparation plan

Not every family needs a tutor for the full run-up, and a good tutor should be upfront with you about that. Where one-on-one support tends to matter most is in the middle phase of selective school test preparation, once your child understands the test format and needs someone who can pinpoint exactly where their reasoning breaks down under pressure – something generic practice books can’t really do.

Because families preparing for these tests are spread right across Australia, from inner Sydney to regional WA, a lot of that support now happens through online selective school tutoring, which gives a child access to a tutor who actually knows their state’s specific selective school placement test, rather than whoever happens to be available nearby.
