# What's Actually on the OC Test? The 2026 Format Explained > The OC test has 3 sections, 79 questions and no writing task. Here's the 2026 computer-based format, verified line by line against the NSW DoE. - URL: https://testacademy.com.au/blog/whats-actually-on-the-oc-test-the-2026-format-explained/ - Category: Guide - Published: 2026-07-09 - Updated: 2026-07-12 - Reading time: 13 min - Tags: oc test, opportunity class, 2026, test format --- **The OC test format in 30 seconds** - Three sections: Reading, Mathematical Reasoning and Thinking Skills. That's 79 questions across 110 minutes of test time. - Every question is multiple-choice, answered on a computer. There is no writing task. - Each section carries an equal weighting of 33.3% of the overall result. - Children sit the test in Year 4 for Year 5 entry the following year. The 2026 test ran on 8 and 9 May, with a make-up test on 22 May. - No calculator is allowed, in any section. Search for what's actually on the OC test and you'll find pages that disagree with each other on the basics: how many questions, how long it runs, even whether the test adapts to your child's answers as they go. Most of that confusion comes from old information written for a version of the test that no longer exists. The current format is published by the [NSW Department of Education](https://education.nsw.gov.au/schooling/parents-and-carers/choosing-a-school-setting/selective-high-schools/placement-test/opportunity-class-practice-tests), and it's simpler than the forums make it look. Everything below has been checked against the Department's own pages, so you can plan around it with confidence. ## The 2026 OC test format at a glance **The Opportunity Class Placement Test, as published by the NSW DoE** | Section | Questions | Time | Weighting | | --- | --- | --- | --- | | Reading | 14 (3 have multiple parts) | 40 minutes | 33.3% | | Mathematical Reasoning | 35 | 40 minutes | 33.3% | | Thinking Skills | 30 | 30 minutes | 33.3% | A detail worth knowing before you tally scores at home: each individual *response* is worth one mark. Three of the Reading questions ask for multiple responses, so they're worth more than one mark each. That's why 14 Reading questions carry the same weight as 35 maths questions. ## Why other sites give you different numbers The OC test moved to computers, and the format that came with that change made a lot of older advice obsolete. We covered the transition in [our guide to the 2025 changes to the Selective and OC tests](https://testacademy.com.au/blog/major-changes-to-selective-and-oc-tests-from-2025). Plenty of pages, though, still quote question counts and section structures from the paper era, and they now sit next to accurate pages in the same search results. Two traps catch even careful parents. First, the DoE's downloadable **PDF practice tests are older, paper-based versions** of the test. The Department says so itself, in bold, on the [practice test page](https://education.nsw.gov.au/schooling/parents-and-carers/choosing-a-school-setting/selective-high-schools/placement-test/opportunity-class-practice-tests): they do not reflect the current format. Only the online computer-based practice tests do. If your child works through a PDF and you count its questions, you'll get numbers that don't match the real test your child will sit. Second, the test is **not adaptive**. It doesn't get harder or easier depending on your child's answers. What the DoE actually describes is several fixed versions of the test, used across different days and the make-up sitting, with some questions common to every version so results can be compared fairly. Those common questions don't affect your child's final score, and the Department states there is no advantage in sitting the test on any particular day. ## Section by section: what your child actually faces ### Reading: 14 questions in 40 minutes The Reading test uses a deliberately wide range of material. The DoE lists non-fiction, fiction, poetry, magazine articles and reports. A Year 4 child who only ever reads novels will meet text types here they rarely see, and poetry trips up more strong readers than any other genre. The pace looks generous on paper, nearly three minutes per question, but each question hangs off a text that has to be read and understood first. ### Mathematical Reasoning: 35 questions in 40 minutes The maths content itself comes from the NSW curriculum up to Year 4. The DoE reviews every question to make sure no extra knowledge is needed, so there's nothing here your child hasn't met at school. What makes the section hard is what it does with that content: multi-step problems, one after another, at roughly seventy seconds each, with no calculator. Speed of recall and calm, accurate working matter more than advanced technique. ### Thinking Skills: 30 questions in 30 minutes This is the section parents know least, because nothing at school looks quite like it. The DoE describes it as testing general critical thinking and problem-solving, and notes that no previous knowledge is required. In practice that means logic puzzles, patterns and reasoning questions at a minute each, the tightest rhythm of the test. Children who've never met the style tend to lose time simply working out what each question is asking. Here's how the three sections compare once you translate them into the thing that actually decides test day, time per question: ## What the OC test doesn't include Knowing what's absent saves prep time. There is **no writing task** on the OC test (that's the Selective test, two years later, which we cover in the [2026 Selective test guide](https://testacademy.com.au/blog/2026-nsw-selective-high-school-placement-test-everything-parents-should-know)). It isn't a general-knowledge quiz, and nothing in it goes beyond Year 4 concepts. Your child answers on a computer provided at the centre; they don't bring their own, and they can't bring pens, rulers, calculators or note paper. Each student is handed two A4 sheets for working out at the start, and can ask for more. ## When and where the test happens The placement test runs in May, and each child attends **one test day only**. Students are allocated to a local test centre based on their primary school's location, usually a nearby public high school, and everyone from the same primary school is tested on the same day. From 2026 the test is held only in NSW. In 2026 the OC test ran on Friday 8 and Saturday 9 May, with the make-up test on Friday 22 May. RECHECK: 2027 OC test dates - confirm against the DoE key dates page once published If you're mapping out the application timeline around those dates, from applications opening through to offers, our [2026 OC placement test guide](https://testacademy.com.au/blog/2026-nsw-opportunity-class-oc-placement-test-everything-parents-should-know) walks through the full year. ## How to prepare for a test in this format Start with the DoE's free [online computer-based practice tests](https://se-practice.au.insights.janison.com/pages/OC). They run in the same software as the real test, show the question types your child might get, and finish with a review screen showing what was right and wrong, with the option to click into every question. That familiarity with the on-screen tools is worth more than any extra worksheet. The PDF practice tests still have a use, extra question exposure with the explanation of answers, as long as you remember they show an older format. After that, the single most useful habit for a Year 4 child is short, timed practice at the real pace. Not marathon sessions: ten Thinking Skills questions in ten minutes teaches the test's rhythm better than an untimed hour, and it keeps practice light enough that an eight- or nine-year-old stays willing. When your child is ready for full-length practice in the current on-screen format, you don't have to pay to start: Test Academy's [practice platform](https://testacademy.com.au/register/) has a free tier with full-length mock tests on a realistic interface and question-by-question analytics, no card needed. The [OC Test Bundle](https://testacademy.com.au/opportunity-class-practice-tests/) adds volume with stepped worked solutions, and [OC Mastery](https://testacademy.com.au/courses/oc-mastery/) (Years 3–4) suits families who want weekly structure with classes capped at 8. Plenty of children also do perfectly well with the official materials and steady practice at home. ## Quick answers to the questions parents ask most **Q: How many questions are on the OC test?** 79 in total: 14 Reading questions (three of which have multiple parts), 35 Mathematical Reasoning questions and 30 Thinking Skills questions. Each individual response is worth one mark. **Q: Is there a writing section on the OC test?** No. The OC test is entirely multiple-choice, with no writing task. The Selective test in Year 6 does include a 30-minute writing task. **Q: Is the OC test adaptive?** No. The DoE uses several fixed versions of the test with some common questions across versions so results can be compared fairly. The test does not change difficulty based on your child's answers. **Q: Can my child use a calculator?** No. The DoE states that students cannot use a calculator during the Mathematical Reasoning test or any other section. Students are given two A4 sheets of paper for working out. **Q: Do the DoE's PDF practice tests show the real format?** No. The Department states the PDF practice tests are from older paper-based versions and do not reflect the current format. Only the online computer-based practice tests simulate the real test. The format, in the end, is the easy part: three multiple-choice sections, 110 minutes, all on screen. Once you stop second-guessing the numbers, preparation becomes a matter of steady reading, quick accurate maths, and enough timed practice that the rhythm of test day feels ordinary rather than frightening. Your child doesn't need to be told the test matters. They need to walk in knowing exactly what it looks like.
