NZ’s Maths Acceleration Trial Delivers Breakthrough Results, Students Double Progress in Just 12 Weeks

A major government-backed trial aimed at lifting maths achievement among intermediate students has delivered striking results, with participating students making twice the progress of their peers in just 12 weeks and retaining those gains months later, Education Minister Erica Stanford has announced.

The findings mark a significant milestone in New Zealand's broader push to reverse declining educational outcomes and ensure all students master foundational skills before entering secondary school.

"We are committed to ensuring young Kiwis are learning the basics brilliantly and getting the support they need to stay on track," Stanford said. "This trial confirms our approach is working—especially for students who need it most."

Accelerated Learning for Students Falling Behind

The Year 7 and 8 maths acceleration programme targeted students who were at least a year behind expected curriculum levels. Across two cohorts involving nearly 3,500 students, the initiative delivered intensive, structured teaching focused on four core areas of mathematics.

Results show that students in the programme achieved up to two years' worth of progress in just 12 weeks, significantly outpacing traditional learning timelines. Even more notably, follow-up assessments conducted three months later confirmed that most of these gains were sustained, addressing a longstanding concern about the durability of short-term interventions.

"This is not just about quick wins—it's about lasting impact," Stanford said.

Second Cohort Confirms Consistent Success

The latest evaluation of a second student group has reinforced the programme's effectiveness. Students who participated in in-person acceleration classes made twice as much progress as those in the control group, who continued with standard classroom learning.

The consistency of results across multiple cohorts suggests the model could be scaled nationally with confidence.

Wider Classroom Reforms Also Showing Gains

Interestingly, the data also highlights broader improvements across the education system. Students in the control group—learning under the new structured maths curriculum—still achieved, on average, a full year's progress in 12 weeks, reflecting the impact of systemic reforms already underway.

These reforms include:

• A mandatory hour-a-day maths instruction policy

• Introduction of internationally benchmarked structured mathematics curriculum

• Deployment of high-quality teaching resources, including over one million workbooks and textbooks

• Professional development for more than 22,000 teachers nationwide

"This shows that transformation is happening not just in targeted programmes, but across classrooms nationwide," Stanford said.

Closing the Equity Gap

One of the most significant findings from the trial is its consistent impact across diverse student groups. Outcomes were broadly similar regardless of students' socioeconomic background, gender, or ethnicity—an encouraging sign for efforts to close longstanding achievement gaps.

"This programme demonstrates that with the right support and teaching approach, every child can succeed," Stanford noted.

Part of a Broader $20 Million Maths Reform Strategy

The acceleration trial is a central component of the Government's Make it Count maths action plan, a multi-pronged strategy designed to lift national numeracy standards.

Key investments and initiatives include:

• $20 million in professional learning and development for teachers

• Stronger maths competency requirements for new teachers

• Early and targeted interventions for struggling students

• Expanded group-based support programmes

• New resources for Year 9 and 10 students who remain behind

The Government has also introduced policies such as "phones away" in classrooms, aimed at reducing distractions and improving focus on core learning.

Nationwide Rollout Underway

Following the success of the trial, the maths acceleration programme is now being made available to schools nationwide, with additional teaching modules and ongoing professional support for educators.

Officials say the goal is to embed early intervention as a standard practice, ensuring students do not carry learning gaps into secondary education.

"Our commitment is clear," Stanford said. "Every child should leave primary school with strong foundational skills and the confidence to succeed."

A Turning Point for Education Outcomes

New Zealand has faced growing concern in recent years over declining literacy and numeracy levels in international assessments. The success of the maths acceleration trial offers a potential blueprint for reversing that trend—combining targeted intervention with system-wide reform.

"Maths is a foundational skill that shapes future opportunities," Stanford said. "We are backing every student's potential and putting the support in place to help them achieve it."

As the programme expands nationwide, educators and policymakers alike will be watching closely to see whether these early gains translate into long-term improvements across the education system.
