The Opportunity Class (OC) test: a parent's complete guide.

What OC actually is

An OC is a full-time class of high-potential Year 5 and 6 students, run inside a mainstream public primary school. It isn't a separate campus or a special school brand — the Department describes both OC and selective high schools as places where "students will learn at a faster pace and explore concepts of increasing difficulty in greater depth," taught by teachers used to working with that cohort.

Because only 89 of NSW's roughly 1,700 public primary schools host an OC class, most successful applicants change schools to take up the place — the Department's own review notes that "in most cases, students will leave their current school to attend a school with an OC." In 2025, 3,459 students were enrolled across all OC classes statewide, a small fraction of the roughly 180,000 students in a typical NSW Year 5–6 cohort.

Who should consider it

There's no local intake area for an OC class — any NSW public or private primary school student can apply, and placement is on test performance alone, not proximity to the host school. It suits a child who's clearly working ahead of year-level content at school and would benefit from a class of similarly able peers moving at the same pace — not a child who's doing fine but whose parents would simply like a label.

It's worth weighing the trade-offs honestly before applying. A successful place usually means changing schools for two years, which can mean a longer commute and leaving an established friend group. And an OC place isn't a pathway guarantee to a selective high school two years later — the two tests are entirely independent, which we cover in detail further down this page.

What's actually on the OC test

Three sections, computer-based, no writing task — unlike the Selective High School test, which adds a fourth, typed writing section. No calculator or ruler is allowed in any section.

That's around 110 minutes of testing in total — noticeably shorter than the Selective High School test's roughly 155 minutes, mostly because there's no writing section and Thinking Skills runs 10 questions and 10 minutes shorter. The test has been delivered on-screen since 2025, on a platform built by testing company Janison — the same contractor and largely the same on-screen interface used for the Selective test.

One detail that surprises a lot of parents: the Department doesn't send home a raw score. Results come back as one of four performance bands — top 10%, next 15%, next 25%, or lowest 50% of that year's candidates — and the Department states explicitly that "test scores or placement ranks are not available and cannot be provided," citing student wellbeing as the reason.

OC entry, by the numbers (2020–2025)

As with the Selective High School figures, the Department doesn't publish a running table of OC applications versus places — the numbers sit in a chart inside the independent review of the disrupted 2025 test. Here they are pulled into one table, with applications-per-place and success rate calculated from the Department's own year-by-year figures.

Source: Dr Michele Bruniges AM, Independent Review of the 2025 Opportunity Class and Selective High School Placement Testing, Appendix 3, Figure 1 (accessed 9 July 2026).

Applications peaked in 2023 at 15,341, then eased back two years running to 13,263 in 2025 — a 13.5% drop from the peak. Selective High School applications followed a similar shape a year later, peaking in 2024 before easing back in 2025 too. The number of places has barely moved: 1,830 in 2020, 1,840 in every year since. Averaged across the six years, that's just under eight applications for every OC place on offer — a noticeably narrower field than Selective High School's roughly four-to-one, simply because there are far fewer OC places (1,840) than Year 7 Selective places (4,227 in 2025) on offer each year.

Timeline

OC applications run on the same annual calendar as Selective High School — they open in early November, close in February, and the test itself is sat in May, with results landing in Term 3. For the 2027-entry cycle, applications opened 6 November 2025 and closed 20 February 2026 (the identical window used for Selective), the OC Placement Test was sat 8–9 May 2026 — about a week after the Selective test — with a make-up sitting on 22 May 2026 for approved illness or misadventure, and outcomes were due in Term 3 2026, historically around early-to-mid September for OC specifically.

Does OC lead to a Selective High School place?

Not automatically, and not directly. The OC test and the Selective High School test are two entirely separate applications, sat roughly two years apart — OC in Year 4 for Year 5 entry, Selective in Year 6 for Year 7 entry — assessed independently by the Department. A student who's been in an OC for two years still has to apply again from scratch and sit the Selective test in Year 6, exactly like a student who was never in an OC at all. Being in an OC doesn't carry any recorded advantage into that later assessment, and missing out on an OC place has no bearing on a family's Selective chances two years later.

What an OC place does tend to offer, in practice, is two years alongside similarly able peers and a curriculum pitched to match — useful preparation in a general sense, but not a formal pipeline.

How to prepare — familiarisation, not coaching

The Department's position on the OC test mirrors its position on the Selective test: "coaching or tutoring for the placement test is not necessary," and there is "no credible research" showing coaching helps a child gain entry. The test "will not need your child to know any new or special knowledge" — it's built to assess intellectual ability and problem-solving, not content a child could be drilled on in advance.

The Department's free public materials are three official sample papers per section, plus free online computer-based practice tests, built on the Janison platform, which it says "will simulate the actual placement tests." Older downloadable PDF versions are also available but reflect a previous, pre-2025 paper-based format, not the current on-screen test. We don't take a position on whether coaching helps beyond that — what we're confident of, regardless of where you land, is that a child who has already sat a timed section on-screen is calmer walking in than one meeting the format for the first time on test day. A closer look at the official OC practice tests → goes through what's in them and where they fall short.

One honest note on our own papers: our current Mathematical Reasoning and Thinking Skills practice papers are built and calibrated to the Year 6 Selective High School test, not the OC test — OC-calibrated papers, matched to Year 4 difficulty and the OC's 30-question Thinking Skills and 14-question Reading format, are in development. The one exception is Mathematical Reasoning's shape: both tests use 35 questions, 40 minutes and 5 options per question, so that section's format is identical even though the difficulty is pitched two years higher in ours. If you're specifically preparing for the Year 6 Selective test, browse our full paper catalogue → — one free paper per subject lets any family preview what the timed, on-screen test experience actually feels like, Selective or OC, since both run on the same style of interface.
