The NSW Opportunity Class (OC) Test is a selective entrance exam that Year 4 students sit to gain entry into Opportunity Class programs in Year 5 and Year 6. Because the test is competitive, a structured preparation plan matters more than last-minute cramming. The most effective approach combines three things: understanding the exam format, practising under realistic timed conditions, and using performance data to target weak areas.
Preparation should start with foundational knowledge of the exam itself. Students who know what to expect walk into the test with more confidence and less anxiety.
The OC placement test is computer-based and sat in Year 4, on devices provided by the NSW Department of Education. It has three multiple-choice sections and runs for under two hours of test time, plus breaks and check-in.
| Section | Time | What it tests | Prep focus |
|---|---|---|---|
| Reading | 40 min | Understanding and interpreting a range of texts | Build stamina Regular timed reading across different text types |
| Mathematical Reasoning | 40 min | Applying maths knowledge to solve problems | Reasoning, not recall Multi-step problems worked against the clock |
| Thinking Skills | 30 min | Critical thinking and problem solving | Shortest section Least time of the three, so pacing matters most here |
| Writing | — | Not part of the OC test | Writing is tested later, in the Selective High School test in Year 6 |

No. The OC placement test has three sections: Reading (40 minutes), Mathematical Reasoning (40 minutes) and Thinking Skills (30 minutes). Writing is not part of it. A writing test does appear in the Selective High School Placement Test, which students sit in Year 6, so writing practice becomes important in the years after the OC test.
Students sit the OC test in Year 4 for entry to an Opportunity Class in Year 5. It is held in May: for Year 5 entry in 2027, the test ran on 8–9 May 2026, with a make-up test on 22 May 2026. Each student attends one test day. Check the NSW Department of Education website for the dates that apply to your child.
A realistic OC mock test uses the same three sections in the same order, the official time limits (40, 40 and 30 minutes), multiple-choice questions, and an on-screen format, since the real test is computer-based. Questions should reflect the current exam pattern. Selectivetrial's full-length OC mock tests are built this way, with question formats updated to align with the latest exam patterns.
Look past the total score. Useful results break performance down by subject and topic, show which question types are costing marks, and let you compare scores across practice sessions to see whether weak areas are improving. Answer explanations matter too, so your child understands why an answer was wrong. Selectivetrial provides topic-wise performance analytics and detailed answer explanations for this reason.
Mock tests are only useful if you learn from them. The key to steady improvement is turning each practice run into data that tells you what to work on next.
What about writing? The OC test has no writing section, so it shouldn't take time away from reading, maths and thinking skills now. It does matter for the Selective High School test in Year 6, where teacher-reviewed writing practice gives specific, actionable feedback rather than just a score.
