Surveys like the Trends in International Mathematics and Science Study (TIMSS) and Programme for International Student Assessment (PISA) enable educators, policymakers and the wider community to compare Australian students with each other, as well as their counterparts across the world. Media coverage of the most recent PISA and TIMSS reports for Australia has focused on students' reports of their classroom climate and behaviour, prompting some concern among policymakers and commentators about what is happening in secondary school classrooms. This Snapshot poses the questions: has the climate in Australian classrooms changed; and have student-teacher relationships deteriorated over the past 15 years? [Australia's participation in the Programme for International Student Assessment 2015 was managed by the Australian Council for Educational Research and funded by Commonwealth, State and Territory Governments.]
