What Is the NSW OC Test? Complete Guide for Parents
A comprehensive guide for parents about the Opportunity Class (OC) Placement Test in New South Wales. covering the test format, eligibility, key dates, scoring, and how to help your child prepare.
Overview of the OC Test
The Opportunity Class (OC) Placement Test is a standardised assessment administered by the NSW Department of Education to identify academically gifted students for placement in Opportunity Classes at select government primary schools. Opportunity Classes provide an enriched and accelerated learning environment for high-potential students in Years 5 and 6.
Each year, thousands of Year 4 students across New South Wales sit the OC test in the hope of gaining entry into one of the 89 primary schools that offer Opportunity Class programs. The test is designed to assess a student's academic potential and reasoning abilities across three key areas: Reading, Mathematical Reasoning, and Thinking Skills.
Since 2022, the OC test has been administered as a computer-based assessment, replacing the traditional pen-and-paper format. Students complete the test on a computer at designated test centres, and the format includes multiple-choice questions across all three sections.
The OC test is a single opportunity. students may only sit the test once, during Year 4, for placement beginning in Year 5. Unlike some other selective entry processes, there is no re-sit option, which makes thorough preparation particularly important.
What Are Opportunity Classes?
Opportunity Classes (OC) are specialised classes within government primary schools that cater to academically gifted and talented students. These classes are available in Years 5 and 6 and are designed to extend and challenge students who demonstrate high academic potential.
Students in OC classes follow the standard NSW curriculum but at a deeper and more accelerated pace. Teachers in these classes are trained to differentiate the curriculum to meet the needs of gifted learners, offering enrichment activities, higher-order thinking tasks, and opportunities for independent research and creative problem-solving.
There are approximately 89 primary schools across NSW that offer Opportunity Classes, with each school typically having one OC class of around 30 students. Some of the most competitive schools, such as Beecroft Public School, Matthew Pearce Public School, and Artarmon Public School, receive significantly more applications than available places.
Who Is Eligible for the OC Test?
The OC test is open to students who are currently enrolled in Year 4 at a government, Catholic, or independent school in NSW, or who are being home-schooled in NSW. Students must be Australian citizens, permanent residents, or hold an eligible visa to apply.
There are no academic prerequisites or minimum grades required to sit the test. any eligible Year 4 student may apply. However, parents should consider whether their child would benefit from and enjoy the more rigorous academic environment of an Opportunity Class.
Applications are submitted online through the NSW Department of Education's High Performing Students portal. Parents must register their child during the application window, which typically opens in the first half of the year before the test is administered.
OC Test Format and Sections
The OC test consists of three distinct sections, each assessing a different area of academic ability. The total testing time is approximately one hour and fifty minutes, with short breaks between sections. All questions are multiple-choice and the test is completed on a computer.
Reading
40 minutes
Tests comprehension of written passages, including literal understanding, inference, vocabulary in context, cloze passages, and the ability to analyse an author's purpose and technique.
Learn more about Reading →Mathematical Reasoning
40 minutes
Assesses mathematical reasoning across number, measurement, geometry, data, patterns, and problem-solving. Content spans Year 4 to early Year 6 concepts.
Learn more about Maths →Thinking Skills
30 minutes
Measures general reasoning ability through pattern recognition, logical deduction, spatial reasoning, and abstract problem-solving. No prior knowledge is required.

Always check the NSW Department of Education website for the most current dates and deadlines.
How Is the OC Test Scored?
The OC test uses a placement score out of 120 to rank students. This score is composed of two components: the test score and the school assessment.
Test Score (100 points)
The combined, scaled result from the three test sections (Reading, Mathematical Reasoning, and Thinking Skills). Raw scores are converted to scaled scores to ensure fairness across different test administrations.
School Assessment (20 points)
A teacher assessment of the student's academic performance in English and Mathematics. This is completed by the student's current school and contributes up to 20 points to the placement score.
The total placement score out of 120 determines the student's ranking and their chances of receiving an offer at their preferred schools. Learn more about how OC scoring and results work.
Computer-Based Testing Format
Since 2022, the OC test has been delivered as a computer-based assessment. Students complete the test on a desktop computer or laptop at an approved test centre, typically a local school. The test uses a secure browser that prevents access to other applications or the internet during the exam.
The computer-based format means students need to be comfortable using a mouse and keyboard, scrolling through passages, and selecting answers on screen. While most Year 4 students are familiar with computers, practising with a computer-based test interface beforehand can help reduce anxiety and improve efficiency on the day.
Students are allowed to use scratch paper provided at the test centre for working out mathematical problems and making notes. However, calculators, dictionaries, and electronic devices are not permitted.
