The Opportunity Class Placement Test is a computer-based test for NSW students in Year 4 who want a place in a Year 5 Opportunity Class. It has three multiple-choice sections and no writing task.

Tips for parents
- Start thinking-skills practice early in Year 3 so the question styles feel familiar.
- Ask your child to explain why an answer is right. Talking it through builds reasoning far more than speed.
- Practise working against a gentle time limit later on, once accuracy is good.
- Keep practice positive: OC is one pathway, and many children thrive without it.
