How many components are in the OC Placement Test?

The NSW Opportunity Class Placement Test has three timed components: Reading (40 minutes), Mathematical Reasoning (40 minutes), and Thinking Skills (30 minutes). There is no writing section. Calculators are not permitted. The printable pack mirrors those section types for home practice.

How should we use these OC sample questions at home?

Ask your child to attempt each question first, then read the worked solution together and discuss where their reasoning matched or differed. One or two questions per session is enough — the goal is to practise explaining method under time pressure.

What does an OC reading inference item look like?

Passage: Maya zipped her pencil case twice, lined up her pencils in a row, and asked the supervisor what time the section would start. When the clock showed one minute before the start, she took a slow breath and turned to the first question.

Question: Which statement is most strongly supported by the passage?

Look for actions that show intent. Lining up pencils, checking the time, and breathing slowly suggest careful preparation. The worked solution in the PDF explains why “Maya wanted to feel ready before the section began” is the best answer.

What does an OC mathematical reasoning item look like?

Question: A sequence begins 2, 5, 11, 23, … What is the next number?

Find how each term relates to the previous one. Here, multiply by 2 and add 1: (2×2)+1=5, (5×2)+1=11, (11×2)+1=23. The next term is (23×2)+1 = 47. The PDF includes the full worked solution and common traps.

What does an OC thinking skills item look like?

Question: Seed is to plant as egg is to ___

State the relationship in words: a seed grows into a plant. An egg grows into a bird. The PDF walks through why “nest” and “shell” do not complete the young-to-adult development pair.

How can my child check their own work?

Before reading the solutions, ask: “Which option did you eliminate first, and why?” For numerical items, estimate whether the answer should be larger or smaller than the starting numbers. For reading, point to the exact phrase that supports the chosen answer.

What should we do next?
