What is on the OC test?

Three sections: Reading (14 questions, 40 minutes), Mathematical Reasoning (35 questions, 40 minutes) and Thinking Skills (30 questions, 30 minutes) — 79 questions in total. There is no writing task. Each section is weighted equally.

Is the OC test adaptive?

No. Like the Selective test, it uses fixed test versions rather than adapting to a student's answers as they go, so it does not get harder or easier in response to how a child is performing.

What score do you need to pass the OC test?

There is no published cut-off and the OC test is not pass or fail. Results are reported as relative bands per section, and offers depend on performance relative to other applicants and the order of your preferences. Roughly one in eight applicants gains a place.

When do students sit the OC test?

In Year 4, for entry into an Opportunity Class in Year 5. Families apply through the NSW Department of Education in the year before, listing up to four placement preferences.

The NSW Opportunity Class (OC) Test, Clearly Explained

A clear, accurate guide to the NSW Opportunity Class Placement Test — the three sections, timing, how placement really works, and how to prepare your child without burnout.

An Opportunity Class is a two-year program for high-potential students, run in Years 5 and 6 at selected public primary schools. Entry is decided by the NSW Opportunity Class Placement Test, sat in Year 4, for Year 5 entry. Like the Selective test, it is computer-based, delivered on the Janison platform with content designed by Cambridge.

The test at a glance

Reading: 14 questions · 40 minutes · 33 answer points
Mathematical Reasoning: 35 questions · 40 minutes · five options each
Thinking Skills: 30 questions · 30 minutes · four options each
Total: 79 questions · no writing task
Weighting: All three sections weighted equally
Format: Computer-based · not adaptive · no calculator

The most important difference from the Selective test is what’s missing: there is no Writing section. The OC test measures reading, mathematical reasoning and thinking skills only, across 79 questions. The trade-off is pace — Thinking Skills gives students just 30 minutes for 30 questions, so time pressure is real.

How placement actually works

This is where most confusion lives, so it’s worth being precise. The Department of Education does not publish raw scores, ranks or cut-off marks — that’s a deliberate policy. Instead, each section result is reported as a relative band, which tells you roughly where your child sat relative to other applicants, not a percentage correct.

Offers then depend on two things together: overall performance and the order of your preferences (you can list up to four). You receive at most one initial offer — your highest qualifying preference.

How competitive is it?

Very. Opportunity Classes are scarce — fewer than 2,000 places against more than 15,000 applicants, which works out to roughly one in eight. From 2027, places are balanced equally between girls and boys. It’s worth keeping perspective for younger children: this is a hard test sat by a nine- or ten-year-old, and the result reflects one morning, not your child’s worth or future.

How to prepare (without the burnout)

For a child this young, the goal is steady capability, not relentless drilling.

Build foundations first. Daily reading, vocabulary and number sense matter far more than worksheets.
Practise in the real format. On a screen, strictly timed — see our realistic OC practice tests.
Get comfortable with pace. Thinking Skills is fast; gentle exposure to timed questions removes the shock on the day.
Review every mistake together. Understanding why an answer was wrong is worth more than the score itself.

The section that most often surprises strong school students is Thinking Skills, and Mathematical Reasoning rewards problem-solving rather than curriculum recall. For a structured runway, Test Academy’s OC Mastery course and its practice platform are the strongest we’ve reviewed for keeping preparation calm, realistic and feedback-rich.
