The gap between Australia’s highest and lowest performers is greater than the OECD average

Australian educational inequality is worse than the OECD average. The 2012 Programme for International Student Assessment (PISA) results confirmed the trend seen in the 2009 results: for mathematical, scientific and reading literacy, Australian students have a wider range of scores (PDF) between the lowest and highest performing students (those who scored between the 5th and 95th percentiles) than the OECD average. This wider range indicates that there is a larger gap between the lowest and highest achievers. Indigenous students are faring the worst, with data showing that across reading, mathematics and scientific literacy, Indigenous students are two-and-a-half years behind their non-Indigenous peers.
