In a recently published OECD report, the disciplinary climate in Australian schools was found to be one of the least favourable across the globe. In contrast the 2020 Alliance of Girls Schools’ Australia Report: The Girls School Edge: A comparison of outcomes for girls from single-sex and co-educational schools, cited PISA data from 2015 and 2018, which provides strong support for the contention that single-sex school students are more likely than co-educated girls to report experiencing learning environments in which they are able to fulfill their learning goals due to substantially lower amounts of disruption or distraction than their counterparts in co-ed schools.
