What's actually on the NSW Opportunity Class test?
Three sections, 79 multiple-choice questions, 110 minutes of testing, done on a computer. Here is what each section is really measuring — and where children lose marks they did not need to lose.
The Opportunity Class Placement Test is sat by children in Year 4, for entry into an opportunity class in Year 5. It is the first academically selective test most NSW families encounter, and it catches a lot of parents off guard — not because it is unfair, but because it does not look much like school work.
The three sections
| Section | Questions | Time | Weighting |
|---|---|---|---|
| Reading | 14 (3 have multiple parts) | 40 min | 33.3% |
| Mathematical Reasoning | 35 | 40 min | 33.3% |
| Thinking Skills | 30 | 30 min | 33.3% |
Reading — 14 questions, 40 minutes
Roughly three minutes per question, which sounds generous until you notice that several questions have multiple parts and every one of them requires going back into the passage.
The passages are not school comprehension. They are often non-fiction — nature writing, popular science, history — pitched slightly above Year 4 reading level, and the questions are layered:
- Literal comprehension — what does the passage say. The easy marks.
- Vocabulary in context — what does this word mean here, which is often not its most common meaning.
- Inference — what the passage implies but never states. This is where most marks are lost.
- Main idea — which single sentence best captures the whole passage. Children pick the option that is true rather than the option that is central.
The common failure is not slow reading. It is answering from memory instead of going back to the text. A child who has read the passage once and then answers from impression will get the literal questions and miss the inference ones.
Mathematical Reasoning — 35 questions, 40 minutes
Under 70 seconds a question. That constraint is the whole design of this section.
The mathematics itself sits inside the Year 4 curriculum — fractions, decimals, area and perimeter, time, money, patterns, simple probability. What makes it hard is that questions are worded as problems rather than sums, often with two or three steps, and frequently with a piece of information that is not needed.
So the skill being tested is not calculation. It is reading a situation and deciding what to calculate. A child who can do the arithmetic but cannot translate the words will run out of time.
Two things make a measurable difference: knowing multiplication facts to the point of not thinking about them, and knowing shortcuts that remove work altogether — for instance cancelling before you multiply fractions rather than multiplying out and simplifying at the end.
Thinking Skills — 30 questions, 30 minutes
One minute per question, and no curriculum content at all. Nothing on this paper is taught in a Year 4 classroom, which is exactly why it is worth preparing for.
What appears here:
- Logical deduction — a set of clues, and one arrangement that satisfies all of them.
- Valid conclusions — given these statements, which conclusion must be true. Not "could be", not "sounds sensible".
- Assumptions — what an argument takes for granted without saying so.
- Flaws in reasoning — why an argument does not hold, even when its conclusion happens to be correct.
- Pattern and sequence — including spatial and visual patterns.
Children who have never met these questions typically guess, then panic at the clock. Children who have been taught a method — eliminate, don't hunt for the answer — go from guessing to accurate in a few weeks. See how logical deduction questions are actually solved.
It's a computer test, and that matters
The test is computer-based: children read the questions on screen and enter answers on the computer at a test centre, usually a local high school. Practising only on paper leaves two things untrained — you cannot annotate a passage the way you would with a pencil, and you have to track your own progress through the section without a visible stack of pages telling you how far you have got.
What good preparation actually looks like
Not more worksheets. Three things, in order:
- Cover Thinking Skills first. It is a third of the mark, it is untaught, and it improves fastest.
- Practise under the real clock. 70 seconds a question in maths, 60 in Thinking Skills. Accuracy without pace is not useful here.
- Go through every wrong answer. A wrong answer is only worth something if the child can say why the right one is right. This is the step that gets skipped, and it is the step that does the work.
The Department of Education publishes free official practice tests, which are the closest thing to the real interface. Start there: NSW Department of Education — opportunity class practice tests.
Preparing for the OC test?
Our OC exam preparation page has the test format, this year's dates and how our classes work. We run live online classes covering all three sections in the real test format — with a teacher on a shared whiteboard, not recorded videos. Homework is corrected and sent back with written feedback, and you get a WhatsApp update after every class. Classes are scheduled in Australian time.
The first lesson is a demo class.
