On the timed digital test, she froze up watching the countdown timer. After a few practice runs, she's learned to pace herself. I'm so glad we discovered this now!

The benchmarking showed us honestly where our child sits compared to others. It helped us have a realistic conversation about expectations and what to focus on next.

These FAQs are for parents who are considering whether their child should apply for OC schools. We aim to go beyond questions like "Who is the test for" (High-potential and gifted children in Year 4), "When is the test" (May 8-9 2026), "What sections are on the test" (Mathematics, Reading and Thinking Skills) and "What is the format of the test" ("Timed and mostly multiple choice).
