OC vs Selective:
What's the difference?

Two of NSW's most sought-after academic pathways — but they're often confused. This guide explains exactly what each program is, when to apply, and how to help your child prepare.

The overview

Two programs, one department, very different entry points

Both Opportunity Class (OC) and Selective High School are NSW Department of Education programs designed for academically gifted students. They are selective — meaning entry is competitive — but they cater to different stages of schooling and use different placement tests. Understanding which one your child is approaching (or whether they might eventually pursue both) is the first step.

In short: OC is a primary school program (Years 5–6), while Selective is a high school program starting in Year 7. A child can attend an OC in Years 5–6 and then separately apply for Selective entry into Year 7.

Deep dive

Opportunity Class (OC): what parents need to know

Opportunity Classes are located at designated NSW government primary schools — not every school has one. If your child is selected, they will travel to the OC school for Years 5 and 6, then return to their local high school or apply for selective entry for Year 7.

How placement works

Placement into an OC is based primarily on performance in the OC Placement Test. In recent years, school assessment data — provided by the child's current school — has also been factored into the overall placement decision alongside the test score. The NSW DoE website publishes the current weighting each year; always check there for the most up-to-date information.

Families nominate up to three OC schools in order of preference during the application process. Placement offers are made based on your child's test result, school assessment, and the school preferences listed.

What the OC Placement Test covers

The Thinking Skills component is often the most unfamiliar for children who haven't encountered this type of question before. It rewards students who can think flexibly and spot patterns — not just recall facts.

Selective High School: what parents need to know

Selective High Schools in NSW are among the most academically competitive secondary schools in the country. Some schools are fully selective (the entire school population is selected), while others have a partially selective stream within a broader comprehensive school.

How placement works

Applications are submitted online through the NSW DoE's application portal during Year 6. Families can typically list a number of selective schools in order of preference. Placement is determined primarily by performance on the Selective High School Placement Test, along with consideration of school assessment data and the preferences listed.

Results — including whether an offer, reserve list position, or non-placement outcome was received — are communicated by the NSW DoE. The process is competitive; most fully selective schools are significantly oversubscribed.

What the Selective Placement Test covers

Choosing a path

Which pathway is right for my child?

These aren't mutually exclusive — many families pursue both. But it helps to think about what you're looking for.

Consider OC if your child...

  • Is currently in Year 3 or early Year 4
  • Is consistently achieving above their year level
  • Would benefit from being surrounded by academically like-minded peers earlier
  • Is comfortable travelling to a different primary school
  • Enjoys reading, maths and puzzle-style thinking

Consider Selective if your child...

  • Is currently in Year 5 or early Year 6
  • Wants an academically stretching high school environment
  • Has strong reasoning and writing ability
  • Is ready for a more competitive and demanding test
  • Is motivated to pursue an accelerated curriculum through Year 12

Both OC and Selective if...

  • Your child is currently in Year 3 or 4
  • You want to maximise academic pathways at each stage
  • Your child is ready to commit to preparation across multiple years
  • You're comfortable with the additional logistics of an OC school in Years 5–6

Neither might be right if...

  • The competitive pressure feels excessive for your child's temperament
  • Your local school already provides strong academic extension
  • Travel to an OC or selective school is impractical for your family
  • Your child thrives in a broader social mix rather than a highly selective cohort
Preparation

How Cleveroo helps with OC and Selective prep

Both the OC and Selective placement tests assess the same core competencies: reading comprehension, mathematical reasoning and thinking skills. The Selective test adds a writing component and raises the difficulty bar across all sections.

Cleveroo's practice platform adapts to your child's current level in each of these areas, filling gaps and progressively building confidence. Short daily sessions — 15–20 minutes — are more effective than marathon cramming sessions, and Cleveroo is designed to make that habit sustainable and even enjoyable for kids.

You can also download free practice test PDFs from Cleveroo to get a feel for the format and difficulty of NAPLAN, OC and Selective questions before committing to a subscription.

Common questions

Parents ask us this all the time.

Is the OC Placement Test harder than NAPLAN?

The OC test is designed to identify academically gifted students, so the reasoning and thinking skills sections go beyond what NAPLAN measures. NAPLAN checks curriculum proficiency; the OC test probes the ability to apply knowledge to novel problems. Most families find Thinking Skills the most unfamiliar component.

Can my child sit the OC test if they attend a private school?

Yes. Applications for the OC Placement Test are open to all Year 4 students — regardless of whether they currently attend a government or non-government school. The same applies to the Selective High School Placement Test for Year 6 students.

What happens if my child doesn't get into OC?

Students who are not placed in an OC continue at their regular primary school for Years 5 and 6. They can then apply for Selective High School in Year 6, completely independently of the OC outcome. Not being placed in OC does not affect Selective eligibility.

How many OC schools can my child be considered for?

The NSW DoE allows families to nominate a number of OC school preferences during the application. Check the current application form on the NSW DoE OC placement page for the exact number of preferences permitted in your application year.

How many Selective High Schools are there in NSW?

NSW has a mix of fully selective and partially selective high schools across the state. The full list — and which are in your area — is published on the NSW DoE Selective High School page. The number and designations can change, so always check the current list.

Does attending an OC improve chances of getting into Selective?

Not directly — Selective placement is based on the Year 6 placement test and school assessment, not on OC enrolment history. However, OC students typically experience an accelerated and enriched curriculum in Years 5–6, which may contribute to stronger preparation for the Selective test.

When should we start preparing?

For OC, most families begin focused preparation 6–12 months before the test — so typically in second half of Year 3 or early Year 4. For Selective, families preparing from Year 5 onwards are well-positioned. Building core skills in reading and maths early, regardless of formal test prep, is always beneficial.

How can Cleveroo help?

Cleveroo offers adaptive daily practice covering reading, mathematical reasoning and thinking skills — the same components that appear in both the OC and Selective tests.
