Following the release of the PISA 2025 results last week, Dominique Beech is joined by Dr Jonas Bertling, Research Director of ACER Implementation and Reporting and co-author of the report sharing Australia’s PISA 2025 results, to unpack the 2025 findings and the implications for educators.

Teacher magazine is delighted to welcome Lisa Rodgers – CEO of ACER – as a columnist. In this first article, she offers a different story about PISA that is built around 5 ideas – position, direction, distribution, resolution and ambition.

The latest OECD Programme for International Student Assessment (PISA) results have just been released. In his latest Teacher column, OECD Director of Education and Skills Andreas Schleicher shares some of the early data and insights, including the changing landscape of reading performance and translating scientific talent into scientific ambition.

The release of the results of the latest cycle of the Programme for International Student Assessment (PISA) made headlines around the world. More than 760,000 students assessed internationally, representing around 33 million 15-year-olds from 91 countries and economies. But the initial data are just the beginning.

Australia’s 15-year-old students continue to perform above the OECD average across science, reading, and mathematics, the latest OECD Programme for International Student Assessment (PISA) results show.

‘The practical challenge of designing units that genuinely extend gifted learners within a mixed-ability classroom, without simply adding more of the same work, remains one of the more complex tasks in primary teaching’. Wesley College’s Lanella Sweet shares a tiered unit of work built around real-world measurement tasks.

The International Mathematical Modeling Challenge (IM²C) invites students around the globe to gather in teams across a 5-day period to solve a real-world problem using mathematical modelling. This year students were asked to inform protection planning for Etosha National Park. In this article, we speak to some Australian schools who participated. 

At EDUtech 2026, the Teacher team caught the Australian STEM Video Game Challenge presentation hosted by Lisa van Beeck, ACER Research Fellow and Project Director for the challenge.

You’ll hear van Beeck walk delegates through the challenge itself and highlight the suite of teacher resources designed to support it.

Last month, the OECD released findings from the 2025 International Early Learning and Child Well-being Study (IELS). In today's episode, Dr Dan Cloney, Senior Research Fellow at ACER and Lead Researcher for IELS, unpacks some of the key findings from the study, explores what made the assessment design unique, and discusses why it's so important to ensure every child arrives at school with the strongest possible foundations.

A new insights report on the latest assessment cycle of the Trends in International Mathematics and Science Study (TIMSS) investigates how much curriculum content is actually covered in classrooms, and whether differences are linked to student achievement.
