When to Start Preparing for the OC Test (Year 3 to Year 4)

Ask five parents when to start preparing for the Opportunity Class test and you'll get five answers, most of them alarming. Year 2. "As soon as they can read." Last year, apparently, and you've already missed it.

The calendar is a lot less dramatic than that. The OC placement test happens on one fixed date in Year 4, the application window sits months before it, and the department that runs the test is on record saying children need very little preparation. What follows is a timeline built around those fixed points — what's worth doing when, and what genuinely isn't. Every fact about the test comes from the NSW Department of Education's own pages, linked as we go and checked on 7 August 2026.

The dates everything hangs off

Working backwards from the test makes the whole thing simpler. The department's published placement stages follow the same shape each round:

When	What happens	Your child is in
November	Applications open	Year 3
February	Applications close — strictly	Year 4
Early May	Opportunity Class Placement Test	Year 4
September	Outcomes released	Year 4
The following year	Placement begins (a two-year program, Years 5–6)	Year 5

Exact dates change each round and live in the Key dates section of the department's application process page. Bookmark it rather than trusting a date you heard at school pick-up — the department is unambiguous that closing dates are strictly observed and late applications are not accepted. Our step-by-step guide to the application covers that half-hour of admin in full.

So the honest answer to "when should we start?" is: the only thing with a deadline is the application, and it opens in November of Year 3. Everything else is your family's choice about pace.

What the department says about preparation

Before planning any of it, it's worth reading what the people who write the test say. From the department's Opportunity Class practice tests page:

It is important to know that coaching or tutoring for the placement test is not necessary. The test will not need your child to know any new or special knowledge.

And a few lines on: "The department does not recommend or endorse coaching for the placement test. There is no credible research that shows coaching helps a child gain entry."

That page also publishes what the department does recommend — free practice tests, in PDF and computer-based form, plus a Student Resource Hub — and says they help a child understand what to expect on test day, learn about the test structure, prepare for the different types of questions, and get tips for taking the test. That word — familiarity — is the entire goal of a Year 4 preparation plan. Our piece on what the department says about coaching quotes the position in full if you want the whole statement.

One more line from the same page belongs in any timeline, because it has real consequences: "Please ensure your child attends school regularly leading up to the test. If they miss too many days without a good reason, we tell the selection committee." Any preparation plan that pulls a nine-year-old out of school is working against the application it was meant to serve.

What your child is actually being asked to do

The test is computer-based, sat in one sitting at a test centre — usually a local high school. As at 7 August 2026, the department's practice tests page lists three components, each weighted equally at 33.3%:

Component	Questions	Time	What it leans on
Reading	14 (3 have multiple parts)	40 minutes	Understanding a range of text types on screen
Mathematical Reasoning	35	40 minutes	Using familiar maths on unfamiliar problems, no calculator
Thinking Skills	30	30 minutes	General critical thinking and problem solving

Two things follow from that table. First, the questions draw on concepts from the NSW curriculum up to Year 4 that your child already learns at school — there is no syllabus to get ahead on. Second, Thinking Skills is a third of the test and, in the department's words, "no previous knowledge is required for this test". It is the section school never explicitly teaches, which makes it the one worth seeing before test day rather than studying for.

For a fuller walk through the sections, see our parent's guide to the OC test.

The timeline

Year 3, Terms 1–3 — nothing test-specific

This is the part nobody wants to hear, and it's the most defensible position in the whole plan. A seven- or eight-year-old does not need placement test practice. What genuinely compounds over these terms is the ordinary stuff: reading widely and talking about what was read, mental arithmetic in real situations, puzzles and games that involve reasoning. None of it looks like preparation, and all of it is.

If you want one concrete thing to do this year, make it reading volume and variety — non-fiction as well as stories. Reading is a third of the test and quietly holds up a second third, because a maths question your child can't parse is a maths question they can't answer.

Year 3, Term 4 (November–December) — apply, and have the conversation

Applications open. Set aside half an hour, have a photo of your child ready for the Test Admission Ticket, and submit it — saving is not submitting, and the window closes in February.

This is also the right moment for a single low-stakes look at the question types, together, at the kitchen table. Not a timed test. Ten or fifteen minutes of "what do you make of this one?" tells you two things worth knowing before you commit a year to anything: whether your child finds this sort of puzzle interesting, and whether the whole idea makes them anxious. Both answers are useful, and either way the application costs you nothing but an evening.

Talk about what an OC place would actually mean — often a new school, a new class, a different commute. A child who has been part of the decision handles both outcomes better.

The summer holidays — rest

Genuinely. If your child enjoys puzzles, let them do puzzles. Beyond that, the return on holiday drilling for a nine-year-old is poor and the cost to their appetite for the year ahead is real. If you want a token habit, ten minutes of reading a day is plenty and doesn't feel like school.

Year 4, Term 1 (February–April) — short, regular, low-key

This is where deliberate practice earns its place, and the shape that works at this age is short and frequent rather than long and intense. Two or three sessions a week of 15–25 minutes is a realistic ceiling for most Year 4 children, and it is enough.

What to spend those minutes on, in priority order:

• Thinking Skills first. It's the unfamiliar third. Patterns, sequences, logic puzzles, "what must be true versus what might be true" — this is the section where familiarity converts most directly into calm on the day.
• Reading on a screen. Comprehension is built by reading, but the on-screen part is a separate small skill. Practising a passage and questions on a computer removes one variable.
• Mathematical Reasoning in short bursts. Word problems and multi-step questions rather than pages of computation. No calculator — rulers and calculators are not allowed in the test either.
• Review, always. Ten questions understood properly beat fifty rushed. Ask your child why the other options are wrong; that habit is close to the whole skill the test measures.

Year 4, Term 2 up to the test (late April–early May) — rehearse the day, then ease off

In the final few weeks, shift from learning to rehearsing:

• Sit one of the department's own computer-based practice tests, in one go. This is the closest thing to the real interface that exists, and it's free. The point is the experience — the timer, the pace, the sequence of sections — not the score.
• Practise moving on. Thirty questions in thirty minutes leaves no room to sink three minutes into one puzzle. A good habit: make a reasoned choice, move, come back if there's time.
• Check the logistics. The Test Admission Ticket is released in your application dashboard about two weeks before the test and must be printed and brought on the day. Pencils, an eraser, water and school uniform are in; calculators, rulers, phones, smart watches and dictionaries are out.
• Taper in the last week. Sleep, ordinary routines, sport and friends. Nothing learned in the final week outweighs a tired child on the morning.

Test day, and the fortnight after

It's one morning: three sections back to back, 110 minutes of testing in total. If your child is unwell or something disrupts their test, there is an illness or misadventure process — a request submitted through the application dashboard within five business days of the test, with approved students able to sit the make-up test. Knowing that exists is the reason not to send a genuinely sick child in "just to get it done".

Then it's a long wait. Outcomes are released in September, and it's worth telling your child that upfront so the silence doesn't feel like bad news.

Signs you've overdone it

Worth checking honestly once a term:

• Reading for pleasure has stopped, because reading has become a task.
• Practice ends in tears, or in an argument, more often than not.
• Your child has started asking whether they're "good enough" rather than whether they got it right.
• The family's mood tracks a practice percentage.
• Preparation is colliding with school hours, sport or sleep.

Any of those is a reason to halve the load, not to push through. This test rewards a child who reads carefully, notices when an answer is only probably right, and keeps moving when one question won't come — and a tired, resentful nine-year-old does less of all three.

If you're reading this later than you'd like

Suppose it's already March of Year 4. You have not missed anything that matters. The department's position is that this test needs no special knowledge, so there is no backlog of content to catch up on. Six to eight weeks of short, calm sessions — with the priority on seeing Thinking Skills questions and sitting one full practice test on a computer — covers the ground that familiarity can cover. The rest was built over years of reading and school, and it's already there.

It's also worth keeping the outcome in perspective while you plan. There are no set minimum entry scores for an offer, because what's needed depends on how many students apply, how they perform, and how many places each class has. Capable children miss out every year for reasons that have nothing to do with effort, and plenty of families skip the OC test entirely and sit the selective high school test in Year 6 instead. Deciding in advance how you'll talk about "no" is part of preparing well.

If you'd like to see the question styles with your child this week, there's a free OC practice set — no sign-up, about five minutes, with worked explanations — and the department's own free practice tests, linked above, are the closest thing to the real interface.
