This report presents evidence on the performance in reading, mathematical and scientific literacy of 15 year old students, their schools and their countries, interpreted from an Australian perspective. It gives insights into factors that influence the development of these skills at home and at school, and discusses implications of the results for policy development. Chapter 5 focuses on results for the Australian states and territories and for other sub-national groups. Results achieved by Indigenous students and by students with language backgrounds other than English are included in this chapter. The sixth chapter describes the Australian PISA participants in some detail, presenting a profile of the Australian schools and students who took part in the study.
