The most common question parents ask when they find out about the NSW Selective test is: "When should we start?" The honest answer depends on where the student currently sits, so treat the timelines below as rough guides, not rules. They are general guidance, not research findings.
This guide covers what each preparation window can realistically deliver, what the risks are at each stage, and one mistake that is worth avoiding whatever your timeline.
Count Back From the Test
Students sit the test in Year 6, in May. The most recent sitting, for Year 7 entry in 2027, was held on 1–2 May 2026, with a make-up test on 22 May. The Department publishes the dates for each year on its placement test page. For a May sitting, "six months out" means roughly November, and "three months out" means roughly February.
The Short Answer
For a student who is performing at or above grade level in literacy and numeracy, six months of structured practice is often enough to be ready on test day. For a student who needs to close gaps in foundational content, twelve months is more realistic. Three months is workable but tight — it leaves little room for error.
Steady practice generally serves a child better than cramming: thirty focused minutes a day for six months tends to beat ten hours in the final two weeks.
12 Months Out: Build the Foundation
Starting a year before the exam is ideal — not because more preparation is always better, but because it allows time for genuine skill development rather than surface familiarity.
At 12 months, the priority is not practice tests. It is:
- Mathematics fluency. Can your child solve multi-step problems without a calculator? Are fractions, decimals, ratios, and proportions solid? Gaps here are better fixed in Year 5 than in the month before the test.
- Reading broadly. Children who read widely — fiction, non-fiction, news — build vocabulary and comprehension stamina naturally. This compounds over time.
- Exposure to Thinking Skills. Introduce logic puzzles, spatial reasoning games, and argument analysis at low pressure. The goal is familiarity, not mastery.
Families who start 12 months out and practise 3–4 days a week often enter the final two months confident and ready to fine-tune rather than scrambling to catch up.
6 Months Out: Structured Practice Begins
Six months is a common starting point for families who have been preparing in the background (reading, maths tutoring, and so on).
At this point, the work becomes deliberate:
- Sit a diagnostic across all four sections. Identify the weakest two areas — those are where to spend most of the practice time.
- Set a regular practice schedule: 30–40 minutes a day, 5 days a week, is easier to sustain than 3-hour weekend sessions.
- Use timed practice from the start. The clock is part of the exam. Students who have never practised under time pressure are often surprised on test day.
- Review every wrong answer. Understanding why an answer was wrong is where much of the learning happens.
By month 4, a student on this schedule can start sitting full practice tests. The final two months are for consolidating, managing timing, and building test-day composure.
3 Months Out: Possible, But Tight
Three months is enough time to improve, but the margin for error is thin. Students starting here should:
- Prioritise Thinking Skills and Reading. Deliberate practice in these sections can pay off quickly. Mathematics gaps that need foundational content re-taught are harder to close in 12 weeks.
- Increase daily practice time. Forty-five minutes every day is a sensible minimum. Sixty minutes is better.
- Focus on the questions they are most likely to see. The Department's published sample tests show the style of each section; students who know those styles well have an advantage.
Three months is not ideal. But it is enough to shift performance if the student is motivated and the practice is focused.
A Mistake Worth Avoiding
A common mistake, whatever the timeline, is this: doing practice without review.
It is intuitive to believe that more practice means better performance. But practice without understanding why wrong answers were wrong can leave students repeating the same errors with increasing speed. The feedback loop — getting something wrong, understanding the reasoning that leads to the correct answer, updating your mental model — is where much of the improvement lives.
Build review time into every session, not just the occasional one.
A Note on Anxiety
The selective test is high-stakes for many families, and preparation can tip from structured to stressful. A few things worth keeping in mind:
First, there is a ceiling on what preparation can achieve. A student's underlying ability limits how much practice can shift their score. Some improvement is always possible; a transformation is not. Framing preparation realistically reduces pressure.
Second, fatigue in the final two weeks is real. The students who peak on test day are often those who maintained consistent practice over months rather than those who crammed in the final stretch. The week before the test should be lighter — consolidation, not new content.
Third, performance on test day can depend on factors outside preparation: sleep, nutrition, and calm. A well-rested student with solid preparation is likely to do better than the same student under-slept and anxious.
Summary
| Timeline | Focus | Risk |
|---|---|---|
| 12 months | Foundation skills + gradual exposure | Burnout if over-scheduled |
| 6 months | Structured timed practice with review | Low if schedule is consistent |
| 3 months | High-frequency focused practice | Content gaps hard to fix this late |
Whatever timeline you are working with, consistent daily practice with genuine review of wrong answers tends to serve children best. The students who improve most are usually not the ones who practise the most hours, but the ones who use each hour most deliberately.
