OC Test Preparation in Years 3 and 4: What Really Helps

29 October 2026 · 6 min read

If your child is in Year 3 or Year 4 and you have started searching for OC test preparation, you are not alone. Lots of families do the same thing at this time of year. The good news is that the things that help most are simple, cheap and quite pleasant to do at home.

One quick note before we start. Details like dates, how the test is run and how places are offered can change from year to year, so always check the NSW Department of Education website for the current information. This article is about the learning side: how to help your child feel ready.

Know what the test is checking

The Opportunity Class (OC) placement test is aimed at Year 4 students applying for Year 5 and 6 classes. It is not a test of what your child has memorised from school. It looks at how well they read, think and reason, including some maths-style problem solving.

That is why heavy cramming rarely works well. A child who reads widely, notices patterns and is comfortable thinking things through is in a much stronger position than a child who has done 40 worksheets in a row and is tired of them.

Think of it as building habits over months, not a sprint over a few weeks.

Build the reading habit first

Reading is the foundation for almost everything else. Questions are made of words, and a child who reads easily has more brainpower left over for thinking.

  • Aim for 20 minutes of reading most days. Chapter books, non-fiction, comics and magazines all count.
  • Mix it up. Try a short story one night and a fact book about sharks, space or trains the next.
  • Talk about it. Ask, "What do you think will happen next?" or "Why did the character do that?"
  • Ask about new words. If your child skips a word they don't know, stop and work out what it might mean from the sentence around it.

Inferring (working out what is not stated directly) is a big skill. A simple way to practise: read a sentence like "Mia looked at the dark clouds and grabbed her umbrella." Ask, "What do we know that the writer didn't say?" Your child will say it looks like rain. That is inference, and you can practise it at the dinner table.

Make thinking skills a game

Reasoning is mostly about spotting patterns and following rules carefully. You can practise both without a worksheet in sight.

  • Number patterns in the car. "2, 5, 8, 11... what comes next? What is the rule?" Then let your child make up one for you.
  • Odd one out. Put four words on the table, such as apple, banana, carrot and grape. Ask which does not belong and why. There can be more than one right answer, and that is the fun part.
  • Logic puzzles and board games. Sudoku for kids, Connect 4, chess, Rush Hour and Mastermind all train careful, step-by-step thinking.
  • Word analogies. "Hot is to cold as up is to...?" Start easy, then make them trickier.

When your child gets one wrong, ask, "Can you tell me how you were thinking?" Often the reasoning is nearly right, and talking it through teaches more than just giving the answer.

Keep the maths sharp and sensible

You do not need to teach Year 6 maths to a Year 4 child. Focus on solid Year 3 and 4 skills and on understanding, not tricks.

  • Times tables and related facts. Knowing 6 x 7 = 42 quickly frees up thinking for harder problems. Short, regular bursts beat long sessions. Our times tables practice is one way to do this.
  • Place value. Can your child say what the 4 is worth in 3,402? Can they work out 1,000 more or 100 less?
  • Word problems. These are where many children stumble. Teach a routine: read it twice, underline the question, circle the numbers, decide what to do, then check if the answer makes sense.
  • Fractions and simple measurement. Cooking is perfect for this. "We need half of 300 millilitres. How much is that?"

Here is a typical problem to try: "Jack has 48 stickers. He gives one quarter to his sister and then buys 15 more. How many does he have now?" Ask your child to explain each step out loud. A quarter of 48 is 12, so he has 36 left, then 51 after buying more. The explaining is the real practice.

If your child is working through Year 4 content, Year 4 maths practice can help fill any gaps.

Practise the test format, but not too much

It does help for your child to meet the style of questions before the day. Unfamiliar formats can make a child nervous, even when they know the content.

A few ideas:

  1. Do a short set of questions, around 10 to 15 minutes, once or twice a week in the months before the test.
  2. Gradually build up to a longer sitting so your child gets used to concentrating for a stretch.
  3. Practise sitting at a table, with no talking, using a pencil, just as it will be on the day.
  4. Teach skipping. If a question is stuck, mark it and move on. Come back if there is time.
  5. After each set, review mistakes together and talk about what to try next time.

One caution: more is not always better. If practice turns into tears or arguments, stop for the day. A relaxed child who practises less will usually do better than a stressed child who practises more.

Look after the whole child

This part matters more than most parents expect.

  • Sleep. Tired children make careless errors. Keep a regular bedtime, especially in the week before the test.
  • Play and downtime. Sport, drawing, free time outside and boredom all help a child's brain.
  • Calm language. Try "I know you will give it a go" instead of "This is really important." Children pick up our worry very quickly.
  • A sensible view of the result. Whatever happens, your child is the same clever, curious kid. Many children thrive in their local school, and there are other ways to extend a keen learner.

It is just one option, and the habits above work with or without any app.

Questions parents ask

When should we start OC test preparation?

There is no magic start date. Building reading and thinking habits through Year 3 is a gentle way to begin. Short, focused practice in the term or two before the test is plenty for most children.

How much practice is too much?

If your child is tired, upset or dreading it, it is too much. A few short sessions a week with plenty of breaks is usually a healthy balance.

Should I hire a tutor?

Many children do well without one. A tutor can help if your child has a clear gap, such as word problems or reading comprehension, but they are not required. Regular reading and relaxed practice at home go a long way.

What if my child gets nervous?

Keep practice low-key, talk about the test as one small thing rather than a big event, and make sure there is fun and rest in the week. Practising in a familiar, calm setting helps nerves a lot.
