The NSW Opportunity Class (OC) Placement Test selects academically gifted students for an Opportunity Class in Year 5. Students sit it in Year 4 across three sections — Reading, Mathematical Reasoning and Thinking Skills. There is no fixed pass mark: placement is competitive, with offers going to the highest-ranked applicants for each school's available places.

The Opportunity Class (OC) test is the entry exam for NSW Opportunity Classes — specialised classes for high-potential students in Years 5 and 6. Children sit the test in Year 4, the year before they would start. This guide explains exactly how it works, what each section measures, and how to prepare sensibly.
The three sections, and what each one measures
The OC test assesses general ability across three areas. There is no writing section — that comes later, in the Selective High School test. Our OC practice tests cover all three sections in the same digital format children meet on the day.
| Section | What it measures |
|---|---|
| Reading | Comprehension and inference — understanding meaning, drawing conclusions and interpreting a range of text types under time pressure. |
| Mathematical Reasoning | Applied problem-solving and multi-step reasoning, rewarding clear thinking over rote arithmetic. |
| Thinking Skills | Logic, pattern recognition and critical reasoning — often the least familiar section for families new to selective testing. |
There is no pass mark
The OC test is not pass-or-fail. Each section score is scaled and combined into a single placement score, every applicant is ranked, and offers go to the highest-ranked students for each school’s available places. Because it is competitive, the effective cut-off changes every year and differs by school. For a fuller answer, read what score you need to pass the OC test.
How to apply
Applications are made online through the NSW Department of Education in the year before the test. Exact opening and closing dates change year to year, so always confirm them on the official DoE Opportunity Class placement page rather than relying on a third party.
A sensible way to prepare
- 1
Get familiar with the format early. Children perform better when the digital screen, timing and question style feel routine. Exam-accurate practice removes the surprise.
- 2
Build all three sections evenly. Reading, Mathematical Reasoning and Thinking Skills each carry weight, so don’t let a strong area mask a weak one.
- 3
Review every mistake. Step-by-step explanations turn errors into understanding — the single biggest driver of improvement.
- 4
Use data to target practice. Percentiles and question-by-question accuracy show exactly where the next gains are, so revision time goes where it counts.
- 5
Consider guided teaching if needed. A structured class can accelerate progress for children who benefit from live explanation and accountability.
Where to go next
When you’re ready to start, the OC practice bundle gives full-length, exam-accurate tests across all three sections with explanations and analytics. For live teaching, the OC Mastery class runs in Parramatta and online across NSW. And to understand how rankings and cut-offs actually work, see what score you need to pass the OC test.
