OC & Selective Test Prep: When to Start (2027 Plan)
If your child is in Year 3 or Year 5 in 2026, Term 4 is a good time to start preparing for the May 2027 OC or Selective test. This guide gives NSW parents a term-by-term plan, the expected 2027 dates, and a checklist for this week.
Many NSW parents of a Year 3 or Year 5 child ask the same question in October: is it too early to start OC or Selective prep, or already too late? Neither. If your child sits the test in May 2027, Term 4 of 2026 is a good time to start, and a little practice, often, is enough.
This guide gives you the whole plan at a glance: when to start, the dates to expect in 2027, what each test covers, and what your child should do this week.
Is This Guide for Your Child?
Yes, if either of these fits:
- Your child is in Year 3 in 2026. They will sit the OC test in Year 4, in May 2027, for entry to a Year 5 Opportunity Class.
- Your child is in Year 5 in 2026. They will sit the Selective test in Year 6, in May 2027, for entry to Year 7.
When Should My Child Start OC or Selective Prep?
If your child is sitting the test in May 2027, start in Term 4 of 2026. You don’t need hours of practice every day. A little, often, is enough.
| When | Main job | What it looks like |
|---|---|---|
| Oct–Dec 2026 | Build foundations | School maths and reading |
| Summer holidays | Keep skills fresh | Light practice and reading |
| Feb–Apr 2027 | Apply and practise | Official practice tests |
| April holidays | Timed practice | Work to the clock |
| Early May 2027 | Test | Stay calm, keep routines |
Short answers to common timing questions
Is Year 3 too late to start OC prep?
No. The OC test is in Year 4, so Term 4 of Year 3 gives your child about seven months.
Is Year 5 too late for Selective prep?
No. The Selective test is in Year 6, so starting in Term 4 of Year 5 works the same way.
How many months should we prepare?
There is no official number. A steady plan from October to May, about seven months, works well for most families.
When Are the OC and Selective Tests in 2027?
Both tests are expected in early May 2027. Here are the key dates.
| Date | What happens | Status | Notes |
|---|---|---|---|
| Nov 2026 | Applications open | Expected | The Department says applications usually open in early November. |
| Feb 2027 | Applications close | Expected | Late applications are not accepted. |
| Feb–Mar 2027 | Official practice tests | Your plan | Try the free online tests and review mistakes together. |
| Apr 2027 | Timed practice in the school holidays | Your plan | Autumn holidays run 12–23 April 2027. |
| Early May 2027 | OC and Selective tests | Expected | Each child sits on one day only. A make-up test is held in late May. |
| Aug–Sep 2027 | Results | Expected | Selective outcomes usually come in August, OC outcomes in September. |
Wondering about NAPLAN? It runs 10–22 March 2027 for Years 3, 5, 7 and 9, so a child in Year 4 or Year 6 won’t sit it that year. See NAPLAN 2027 dates.
What Is on the OC Test and the Selective Test?
Both tests are multiple choice, done on a computer, with no calculator. The questions draw on the NSW curriculum up to Year 4 (OC) or Year 6 (Selective).
What does the OC test include?
| Section | Questions | Time |
|---|---|---|
| Reading | 14 | 40 minutes |
| Mathematical Reasoning | 35 | 40 minutes |
| Thinking Skills | 30 | 30 minutes |
Each OC section is worth one third of the mark.
What does the Selective test include?
| Section | Questions | Time |
|---|---|---|
| Reading | 17 | 45 minutes |
| Mathematical Reasoning | 35 | 40 minutes |
| Thinking Skills | 40 | 40 minutes |
| Writing | 1 task | 30 minutes |
Each Selective section is worth one quarter of the mark.
Is Your Child Ready for the OC or Selective Test?
Use this quick check to see where to focus first.
| Doing well | Needs some practice | Needs support now |
|---|---|---|
| Understands year-level maths | Slow with basic calculations | Has clear gaps in school maths |
| Reads regularly | Makes careless mistakes | Avoids reading |
| Can explain how they solved a problem | Gets stuck on unfamiliar questions | Is getting very anxious about the test |
| Stays calm when a question looks new | Finds timed work uncomfortable | The teacher has raised concerns |
Your child doesn’t need to be “perfect” before preparation starts. First make sure the basics are strong. Then use test practice to build speed and confidence.

Parent tip: Term 2 starts on Thursday 29 April 2027. If the test follows its usual pattern, it will fall in the first two weeks of term. Keep both possible test days free until your child’s ticket arrives.
What Should My Child Do This Week?
If you’re reading this in October 2026, start here. Tick each one off as you go.
- ☐ Check your child’s year-level maths skills
- ☐ Set up a regular reading time
- ☐ Look at one official practice test together, untimed
- ☐ Write down 1–2 areas that need work
- ☐ Set a reminder for when applications open in November
Skip for now: heavy test drilling.
What Are the Common Myths About OC and Selective Prep?
These five come up a lot. Here’s what is actually true.
| Myth | Reality |
|---|---|
| “You need to start in Year 2.” | Starting earlier isn’t automatically better. A steady plan from Term 4 gives about seven months. |
| “My child needs to learn high school maths.” | The tests draw on the school curriculum up to Year 4 (OC) or Year 6 (Selective). |
| “More practice always means better results.” | Short, regular, focused practice is easier to keep up than cramming, and leaves time to rest. |
| “You can apply any time before the test.” | There is a fixed window, usually November to February. Late applications are not accepted. |
| “A tutor can guarantee a place.” | No one can guarantee a place. Good support builds skills and confidence. |

Can Tutoring Help With OC and Selective Prep?
Yes, when it builds skills instead of drilling tricks. The Department says the tests need no new or special knowledge, and it does not endorse coaching. So good support is not about tricks. It is about stronger skills and a steady routine.

How many months should we prepare for the selective test?
There is no official number. A steady plan from October to May, about seven months, works well for most families.
What is tested in the OC test?
Three multiple-choice sections: Reading (14 questions, 40 minutes), Mathematical Reasoning (35 questions, 40 minutes) and Thinking Skills (30 questions, 30 minutes). Each is worth one third. Questions draw on the NSW curriculum up to Year 4.

Keep them home. Submit an illness or misadventure request in your application dashboard, usually within 5 business days, with evidence such as a medical certificate. If it is approved, your child may sit the make-up test.

I write because I like understanding things properly, and I've never been able to do that quietly.
Six years in, what still interests me most isn't the writing itself. It's the person on the other side. Who are they, what were they actually worried about when they opened this page, and did they leave with what they came for? Most content fails that last test. It answers the easy question instead of the one that was asked.
At Cuemath, I write for parents and students in India and around the world. That range is the part I enjoy. A parent in Bangalore and a parent in Canada are asking about the same child, but not always in the same words, and that difference matters.
So I research before I write. Not just search results. Forums, reviews, the long comment threads where somebody finally admits what they're really confused about. That's usually where the useful thing is hiding.
I also spend time on how people find this writing at all, since a growing number of them now ask an AI instead of typing into Google. But that only works if the writing is clear to begin with. There's no shortcut around that part.
