"When another parent at school drop-off mentioned the OC test, I nodded along but had no idea what she was talking about. I wish I had found a simple, no-jargon guide like this months earlier."

About This Guide
This guide is written for parents who are completely new to the Opportunity Class system. All information is based on the NSW Department of Education's official Opportunity Class Placement guidelines and verified 2026 test specifications.
Quick Answer: What Is the OC Test?
The OC test (also called the opportunity class placement test or OC exam) is a free, computer-based assessment run by the NSW Department of Education to select academically gifted Year 4 students for placement in OC classes NSW during Years 5 and 6. The opportunity class test has three equally weighted multiple-choice components — Mathematical Reasoning (35 questions, 40 minutes), Reading (25 questions, 30 minutes), and Thinking Skills (30 questions, 30 minutes) — with no writing section. There are 89 OC schools across New South Wales. For 2027 entry, the year 4 OC test is scheduled for 8–9 May 2026, with applications closing 20 February 2026. Up to 20% of places are reserved under the equity placement model. The entire process — application, testing, and placement — is completely free.

What Does OC Stand For?
OC stands for Opportunity Class. These are specialised OC classes NSW government primary schools host for academically gifted and high-potential students in Years 5 and 6. An opportunity class is not a separate school — it is a class of approximately 30 students that operates within an existing public primary school, sharing the same playground, library, and school community while following an enriched and accelerated curriculum.
There are currently 89 OC schools across New South Wales, spread from the Sydney metropolitan area to regional centres. Each school with an OC class offers one or two classes per year group, meaning places are limited and entry via the opportunity class test is competitive.
Quick Summary
Opportunity Class = a specialised class for gifted students in Years 5–6, inside a regular NSW public primary school. It is free, government-run, and available at 89 schools across the state.
The key thing to understand is that OC is part of the NSW public education system. There are no tuition fees, no entrance charges, and no ongoing costs beyond what you would pay at any government school. Your child is placed through a standardised test process managed by the NSW Department of Education.
Why Do Opportunity Classes Exist?
Opportunity Classes were established to meet the learning needs of academically gifted children who may not be sufficiently challenged in a regular classroom. The idea is straightforward: when high-ability students learn alongside peers of similar capability, they can work at a faster pace, tackle more complex problems, and engage in deeper discussions without holding back or feeling out of place.
The NSW Department of Education recognises that every child deserves an education tailored to their ability level. Just as students who need additional support receive targeted help, students who are significantly ahead of their peers benefit from a programme that stretches and challenges them. OC classes serve this purpose within the public system.
The programme has been running for decades and has a strong track record. Many OC students go on to sit the Selective High School Test in Year 6 and gain entry to selective high schools for Year 7. For a detailed comparison between the two pathways, see our OC test vs selective test comparison guide.
Who Can Apply for the OC Test?
Eligibility for the OC test is broader than many parents realise. You do not need a teacher recommendation, a prior gifted identification, or any special documentation. The basic requirements are:
- Year level — Your child must be enrolled in Year 4 at the time of the test (they enter OC at the start of Year 5)
- School type — Children from NSW government schools, Catholic schools, and independent schools can all apply
- Residency — Australian citizens, permanent residents, and holders of certain qualifying visa categories are eligible
- No geographic restriction — You can apply for OC schools anywhere in NSW, regardless of where you live
- Home-schooled students — Eligible if they meet age and residency requirements
No Gifted Label Required
Your child does not need to be formally identified as "gifted" by their school to apply. Any eligible Year 4 student can sit the OC test. The test itself is the assessment.
The application is submitted online through the NSW Department of Education's placement portal. You will need your child's Student Registration Number (SRN), which their current school can provide. There is no application fee — the entire process is free.
How the OC Test Works: Opportunity Class Test Format Explained
This is where many parents feel most confused, so let us break down the OC test format clearly.
The OC test is a computer-based assessment held at designated external test centres across NSW — not at your child's own school. The opportunity class placement test consists of three components, each weighted equally at approximately 33.3% of the total score. There is no writing component in the OC exam.
OC Test Components at a Glance
Three equally weighted sections, all multiple-choice
Mathematical Reasoning
40 minutes — problem-solving, number sense, geometry
Reading
30 minutes — comprehension across text types
Thinking Skills
30 minutes — logic, patterns, abstract reasoning
Mathematical Reasoning (40 minutes, 35 questions)
This section assesses your child's ability to apply mathematical concepts to solve problems. It goes beyond simple arithmetic — questions test number sense, algebraic thinking, measurement, geometry, data interpretation, and multi-step problem-solving. Calculators are not permitted. Your child needs strong mental arithmetic skills and the ability to reason through unfamiliar problem types.
Reading (30 minutes, 25 questions)
The Reading section presents a range of text types — fiction, non-fiction, poetry, and informational passages — followed by comprehension questions. Your child will need to identify main ideas, make inferences, understand vocabulary in context, and analyse how authors structure their writing. Building a strong reading habit from an early age is the single best preparation for this component.
Thinking Skills (30 minutes, 30 questions)
Often the most unfamiliar component for students, Thinking Skills tests abstract and logical reasoning. Questions involve pattern recognition, sequences, spatial awareness, and the ability to identify relationships between shapes, numbers, or concepts. This section is designed to assess innate reasoning ability rather than learned content, which makes it both the hardest to "study for" and the most important to practise.
No Writing Component
Unlike the NSW Selective High School Test (sat in Year 6), the OC test does not include a writing section. All questions across all three components are multiple-choice.
All questions are multiple-choice with four or five answer options. There is no partial credit — each answer is either correct or incorrect. The combined testing time is 100 minutes across the three sections, with short breaks in between.

How OC Placement Works: From OC Test Results to Offers
Understanding how places are allocated helps you make smarter decisions during the application process. Here is how OC test results translate into placement offers:
The OC Placement Process
Your Child Sits the Test
The three test components produce a combined score. All students across NSW are ranked on the same scale.
Preferences Are Considered
During application, you list your preferred OC schools in ranked order. You can nominate multiple schools. The order matters — place your most-desired school first.
Score-Based Allocation
Places are offered to the highest-scoring applicants first. If your first-preference school is full when your child's score is reached, the system moves to your second preference, and so on.
Equity Model Applied
Up to 20% of places at each OC school are reserved under the equity placement model, ensuring students from disadvantaged backgrounds have fair access to the programme.
Offers and Reserve List
You receive an offer for a specific school, or your child is placed on a reserve list. Reserve list offers can continue well into the school year as other families decline places.
The 20% Equity Placement Model
This is an important feature of the OC system that many parents are unaware of. The NSW Department of Education reserves up to 20% of OC places for students from educationally disadvantaged backgrounds. This ensures that the programme is not exclusively accessed by families with the resources for extensive private tutoring. The equity model considers factors such as socioeconomic background, geographic isolation, and other indicators of educational disadvantage. The remaining 80% of places are filled purely on merit based on test scores.
Choosing Your Preferences Wisely
You can list multiple OC schools during your application. Think carefully about:
- Proximity to home — Your child will attend this school for two years in Years 5 and 6
- School reputation and culture — Visit open days if possible
- Transport logistics — Consider daily travel time and safety
- Competitiveness — Some OC schools have significantly higher cut-off scores than others
- Second and third preferences — Listing realistic back-up options increases your child's chances of receiving an offer
What Life Is Like in an OC Class
If your child is offered a place, what can you actually expect? Here is a realistic picture of the OC experience.
Curriculum: OC classes follow the standard NSW syllabus but go deeper and further. Teachers introduce advanced concepts, set more challenging problems, and encourage independent research and critical thinking. The pace is noticeably faster than a regular class.
Teaching: OC teachers are experienced in working with high-ability students. They are trained to differentiate instruction upwards, provide enrichment activities, and foster an environment where intellectual curiosity is celebrated rather than stifled.
Peers: Your child will be learning alongside approximately 30 other academically selected students. Many families report that this peer group is one of the greatest benefits — children feel "normal" for being enthusiastic about learning, and friendships formed in OC often last well beyond primary school.
Workload: Expect a greater volume and complexity of homework compared to regular classes. This is manageable for most OC students but can be an adjustment in the first term.
Social life: OC students participate fully in the broader school community — sport, assemblies, excursions, and playground time are shared with all students. Your child is not isolated from the wider school.
OC Classes vs Regular Classes
A side-by-side comparison for parents
| Feature | Option 1 | Option 2 | Verdict |
|---|---|---|---|
| Curriculum | Extended and enriched | Standard NSW syllabus | OC adds depth and challenge |
| Pace | Accelerated | Standard progression | OC moves faster through content |
| Peer Group | Academically selected | Mixed ability | OC offers like-minded peers |
| Class Size | ~30 students | ~25–30 students | Similar sizes |
| Cost | Free (public school) | Free (public school) | No additional fees |
| Teacher Training | Gifted education focus | General primary | OC teachers specialise in extension |
| Selective Test Prep | Strong foundation built | Standard preparation | OC students often well-prepared for Year 6 test |
Is OC Right for Your Child?
This is the most important question — and it deserves an honest, balanced answer. OC is a wonderful opportunity, but it is not the right fit for every child or every family.
OC may be a great fit if your child:
- Is consistently ahead of their peers academically and finds regular classwork too easy
- Loves learning and seeks out challenges independently
- Handles pressure and competition in a healthy way
- Is comfortable (or can become comfortable) with a faster-paced learning environment
- Would benefit from being surrounded by academically motivated peers
OC may not be the best fit if:
- Your child is happy and thriving in their current school environment
- The logistics of travelling to a different school would create significant family stress
- Your child is high-achieving but anxious about tests and competition
- You are primarily motivated by prestige rather than your child's genuine needs
- Your child would be leaving a school where they have strong social connections and support
A Balanced Perspective
There is no shame in deciding OC is not the right path for your family. Plenty of high-achieving students thrive in regular classes and go on to excel in the Selective High School Test, private school scholarships, or other pathways. OC is one option among many.
The best approach is to have an open conversation with your child. Ask them how they feel about school, whether they want more challenge, and how they would feel about changing schools. Their wellbeing and enthusiasm matter far more than any test score.
Common Myths About OC Debunked
There is a lot of misinformation circulating in parent groups and online forums. Let us set the record straight on the most common myths.
Myth 1: "You need expensive tutoring to get into OC." Reality: While structured preparation helps, many students gain OC placement with a combination of home-based practice, regular reading, and a solid school education. Expensive tutoring is not a prerequisite for success.
Myth 2: "OC is only for children who are already identified as gifted." Reality: Any eligible Year 4 student can apply. There is no requirement for a prior gifted identification, teacher recommendation, or IQ test. The OC test itself is the assessment.
Myth 3: "OC kids are under too much pressure." Reality: OC classes are designed to challenge, not overwhelm. The environment is supportive, and most OC students report feeling more engaged and happier because the work matches their ability level. However, parental attitudes play a huge role — if you frame OC as high-pressure, your child will feel that pressure.
Myth 4: "If my child misses out on OC, their academic future is ruined." Reality: Absolutely not. The Selective High School Test in Year 6, private school scholarships, and many other pathways exist. Missing out on OC is disappointing but it is not a defining moment in your child's life.
Myth 5: "OC students have no social life." Reality: OC students participate in all school activities — sport, creative arts, excursions, and playground time — alongside the broader school community. They are not isolated.
Myth 6: "The test is only about how much content your child has memorised." Reality: The OC test — particularly the Thinking Skills component — is designed to assess reasoning ability, not rote-learned content. Problem-solving, pattern recognition, and comprehension are what matter most.
Myth 7: "All 89 OC schools are equally competitive." Reality: Cut-off scores vary significantly between schools depending on location and demand. Some OC schools are far more competitive than others, which is why your preference order matters.
Frequently Asked Questions
1. What age is my child when they sit the OC test?
Most children are 9 or 10 years old when they sit the OC test during Year 4. If successful, they enter an OC class at the start of Year 5.
2. Is the OC test the same as the Selective High School Test?
No. The OC test is for entry into Years 5–6 classes at primary school, while the Selective High School Test is for Year 7 entry at secondary school. The OC test has three components (no writing), while the Selective test has four (including writing). For a full comparison, read our OC test vs selective test comparison guide.
3. Does my child sit the test at their own school?
No. The OC test is held at designated external test centres across NSW. You will receive your assigned test centre details after your application is confirmed.
4. How much does it cost to apply?
Nothing. The OC test application and sitting are completely free. There are no registration fees or administrative charges. Be wary of any third-party website charging for "OC registration."
5. Can my child apply from an independent or Catholic school?
Yes. Children from NSW government schools, Catholic schools, and independent schools are all eligible to apply. The placement is into a NSW government school OC class.
6. How many OC schools are there in NSW?
There are 89 OC schools across New South Wales, spread from metropolitan Sydney to regional areas. Each school typically has one OC class per year group.
7. What happens if my child is sick on test day?
Contact the NSW Department of Education's School Placement Unit immediately. A make-up test is scheduled for 22 May 2026. You will likely need to provide a medical certificate.
8. Can my child resit the OC test if they are unsuccessful?
No. The OC test is a one-time opportunity taken in Year 4 for Year 5 entry. There is no option to resit in a subsequent year. However, the Selective High School Test in Year 6 provides another pathway for academically talented students.
9. What is the equity placement model?
The NSW Department of Education reserves up to 20% of OC places for students from educationally disadvantaged backgrounds. This ensures the programme is accessible to a diverse range of students, not only those with access to extensive private preparation.
10. When should my child start preparing?
Most education specialists recommend starting structured preparation 12 to 18 months before the test — which means during Year 3 for most students. This allows time to build skills gradually without cramming. Explore our OC practice tests to begin.
11. Is the OC test multiple-choice only?
Yes. All questions across all three components — Mathematical Reasoning, Reading, and Thinking Skills — are multiple-choice. There are no written responses, short answers, or essays in the OC test.
12. Can my child transfer between OC schools after placement?
Transfers between OC schools are generally not permitted unless there are exceptional circumstances, such as a family relocation. The school you accept during the placement process is where your child will attend for Years 5 and 6. Choose your preferences carefully during application.
How many questions are on the OC test in total?
The OC test contains a total of 90 multiple-choice questions across three components: Mathematical Reasoning has 35 questions (40 minutes), Reading has 25 questions (30 minutes), and Thinking Skills has 30 questions (30 minutes). The combined testing time is 100 minutes with short breaks between sections. Every question offers four or five answer options with no partial credit — each answer is either correct or incorrect. There is no writing component in the opportunity class test NSW.
When do OC test results come out?
OC test results for the 2026 testing cycle (2027 entry) are expected to be released in late September 2026. Results are communicated through the NSW Department of Education's online placement portal. Successful candidates receive placement offers immediately, while reserve list offers may continue into Term 4. Parents should check the portal regularly once results are due, as email notifications can sometimes be delayed.
Can Year 3 students sit the OC test?
No — the year 4 OC test is sat during Year 4, not Year 3. However, applications are now submitted when students are in Year 3 (the NSW Education Department moved the application timeline earlier from 2026 onwards). For 2027 entry, applications closed on 20 February 2026 when students were in Year 3, but the opportunity class placement test itself is administered on 8–9 May 2026 when those students are in Year 4. This means families need to be aware of the OC pathway well before their child reaches Year 4.
What is the difference between the OC test and the selective high school test?
The OC exam and the NSW Selective High School Test are separate assessments for different stages of education. The OC test is for Year 4 students seeking entry to Year 5–6 opportunity classes in primary school, while the Selective test is for Year 6 students entering Year 7 at selective high schools. The OC test has three components (no writing), while the Selective test has four components including a writing section. Both are free, computer-based, and managed by the NSW Department of Education, but they assess different skill levels appropriate to each age group.
Is the opportunity class test the same every year?
No. The NSW Department of Education commissions a new opportunity class test each year, so questions are never repeated from previous cycles. While the OC test format remains consistent — three multiple-choice components covering Mathematical Reasoning, Reading, and Thinking Skills — the specific questions, passages, and problems change annually. This means practising with past papers helps with format familiarity and skill development, but memorising answers from previous tests provides no advantage.
Start Your Child's OC Journey with Confidence
Understanding the OC system is the first step. Whether you decide to pursue Opportunity Class placement or not, being informed means you can make the best decision for your child and your family. If you do decide to proceed, start early, keep preparation balanced, and remember that your child's wellbeing comes first — always.
