Should your child sit the OC exam? The answer is almost always yes.

The NSW Opportunity Class Placement Test is an exam students sit in Year 4 to gain entry into an Opportunity Class for Years 5 and 6. OC classes are accelerated learning environments within primary schools, designed for students who are ready to move faster than a standard classroom allows.

There is no cost to apply for or sit the OC exam. This makes it one of the few genuinely free opportunities for families to assess where their child sits academically relative to a competitive cohort, with no financial commitment attached.

As of 2026, there are 89 opportunity classes across NSW: 88 in primary schools, with 57 in metropolitan Sydney and 31 in rural or regional centres, plus Aurora College which provides online classes for rural and remote students. There are 1,840 places available in Year 5 across the state. From 2027, places are allocated equally between boys and girls, with the remaining place in each class filled on academic merit regardless of gender. This gender-split allocation mirrors how the Selective exam works from 2027, so students sitting the OC exam will already be familiar with how results are assessed when they reach the Selective process two years later.

In most cases, students who accept an OC place will move to the school hosting the class for Years 5 and 6. Students attend full-time. Some OC classes are composite Year 5 and Year 6 classes with 15 students per year level. Others run as two separate single-year classes with 30 students per intake. It is worth checking directly with any school of interest to confirm which structure they run.

Entry is competitive. Each school has its own minimum score threshold, and that threshold varies significantly between schools depending on demand. Higher-demand OC classes in areas with strong academic communities can be very difficult to get into. Others may have lower thresholds. The minimum score in a given year can shift depending on how many students apply and how they perform, though it tends to remain fairly stable year to year. Using previous years' results as a guide gives families a reasonable sense of which schools are realistically within reach.

One of the most common reasons parents hesitate to enter their child for OC is that they are not sure they actually want to move their child to a different school. Separate drop-offs, losing friends, disrupting a working routine.

This is a reasonable concern. It is also not a reason to avoid sitting the exam.

If a student sits the exam and does not receive an offer, the family has lost nothing except the time spent preparing, which as noted above was Selective preparation in any case. If a student sits the exam and does receive an offer, the family then gets to make a considered decision about whether to accept it. Receiving an offer and declining it is a completely valid outcome. It tells you your child was competitive enough to earn a place. That is useful information regardless of what you do with it.

The friends concern is also worth addressing directly. A student who does not attend OC will still face the same social transition when they start Year 7. Most primary school friendship groups change significantly at the high school transition regardless of whether a student attended OC. Attending OC in Years 5 and 6 means the social transition happens earlier, in a smaller environment, before the larger disruption of high school entry. Many students find making friends in an OC class easier than expected.
