The NSW Opportunity Class (OC) Placement Test is a computer-based exam sat in Year 4, for entry into an Opportunity Class — an enriched class for academically capable students in Years 5 and 6 at selected public primary schools.
The three sections
The OC test has three sections and 79 questions in total. Each section is weighted roughly equally, so a child can’t lean too heavily on a single strength.
- Reading — 14 questions in 40 minutes. Comprehension across different text types, with on-screen formats such as cloze passages and drop-down choices.
- Mathematical Reasoning — 35 questions in 40 minutes, five answer options each. Applied problem-solving rather than plain calculation.
- Thinking Skills — 30 questions in 30 minutes, four answer options each. Logic, patterns and careful reasoning.
Notice what’s not there: unlike the Selective test, the OC test has no writing task. We line the two up side by side in OC vs Selective.
What makes it challenging
The biggest hurdle is often age, not difficulty. These are demanding reasoning questions for a child of about nine or ten, sat on a computer under timed conditions. Reading 14 questions in 40 minutes is comfortable on pace, but the stamina to stay focused across three sections is a real factor for young children — and one worth practising.
How it’s scored
OC results are reported as relative standing against other applicants and used to build a merit list — there’s no fixed pass mark. We explain this in how OC placement works.
The best preparation mirrors the real thing. Working through realistic, on-screen OC practice tests helps a young child get comfortable with the format, the timing and sitting still through a longer assessment.
