The transition in 2025 from paper-based to computer-based placement tests for NSW Opportunity Class (OC) and Selective High Schools brought significant challenges – and valuable lessons.
This guide distills those lessons and offers detailed advice for parents to help their children succeed in the new testing format. We’ll explore:
- What went wrong during the 2025 rollout
- How to prepare both academically and technically for online exams
- A comparison of preparation resources
- Tips to manage test-day stress and uncertainty
By understanding the new format and using the right strategies, you can help your Year 4 (OC) or Year 6 (Selective) student approach the tests with confidence.
Lessons Learned from the 2025 Test Rollout Disruptions
The 2025 rollout of computer-based OC and Selective tests faced major disruptions that highlighted the need for stronger planning and fairness safeguards.
At one large Sydney venue, more than 2,500 students and parents were caught in chaos. The Public Order & Riot Squad was even called in after widespread technical failures – such as students being unable to connect to the test Wi-Fi – caused hours-long delays (9news.com.au).
The schedule quickly unraveled: the second exam session of the day was cancelled on the spot after the 8:00 AM session ran over 90 minutes late. These events led to public outcry, an official review, and an apology from the Education Minister, who admitted that “this isn’t good enough” and pledged to investigate what went wrong (9news.com.au).
Key Takeaways: Infrastructure, Logistics, and Communication
One major lesson was the need for better technical infrastructure and logistics.
- Inadequate internet connectivity
- Poor crowd management
- Lack of signage and slow pick-up procedures
All contributed to the chaos (9news.com.au).
In response, the NSW Department of Education moved rescheduled tests to over 30 smaller, school-based centers rather than relying on a few massive venues (education.nsw.gov.au). This shift showed the benefit of decentralizing test sites to reduce overcrowding and improve efficiency.
Fairness and Resits: A Controversial Dilemma
Another key lesson concerned fairness.
Because tests were held over several days (May 2–4, 2025) and some sessions were cancelled mid-stream, the government allowed affected students to re-sit the test on later dates (education.nsw.gov.au).
However, this caused controversy:
- Around 20% of students were allowed to take the test twice and keep their highest score.
- Many parents felt this was “really quite unfair,” arguing it gave those students a “best of two” advantage (abc.net.au).
Families whose tests weren’t disrupted worried their children’s scores would be compared against resit students who had a second chance.
The Department defended the decision as the fairest option under the circumstances, noting that:
- New test content was used for all resits to prevent question overlap
- Multiple equivalent test versions had been pre-calibrated for consistent difficulty
- Statistical scaling ensured no group was advantaged based on their test day
(education.nsw.gov.au)
Still, the experience showed how important it is to have transparent contingency policies. Families should be informed in advance about how makeup exams and scores will be handled – to prevent confusion and frustration.
What Parents and Schools Can Learn
In summary, 2025 taught all stakeholders to expect the unexpected and have strong backup measures in place.
Success in future test rollouts depends on:
- Robust technical preparation
- Smaller or staggered testing locations
- Clear communication with families
- Fairness safeguards like pre-calibrated test versions and transparent scoring protocols
These lessons are now shaping how parents, students, and schools approach the new computer-based tests in 2026 and beyond.
