The Programme for International Student Assessment, more popularly referred to as PISA, measures how well 15-year-olds are prepared to use their science, reading and mathematics skills in real-life situations. More than half a million students from 72 countries and partner economies took part in the 2015 test cycle and the results have just been released. The Australian report, PISA 2015: A first look at Australia’s results, from the Australian Council for Educational Research, doesn’t make for pleasant reading. Dr Sue Thomson, ACER Director of Educational Monitoring and Research and lead author of the report, joins me to discuss the results.
