Results from international programs that assess the skills and knowledge of young people have indicated that Australia’s Indigenous students perform at a significantly lower level than non- Indigenous students. An in-depth comparison of Indigenous and non-Indigenous students’ performance on the Programme of International Student Assessment (PISA) across three cycles is provided in an accompanying volume to this report, while the current report provides an understanding of how various aspects of students’ background and psychological constructs relate to each other and to student performance. Chapters 2 through 5 each focus on a different group of potential influences on the performance of students, comparing the profiles of Indigenous and non-Indigenous students, while Chapter 6 presents results of multivariate analyses that assess which factors have a significant impact on the reading, mathematics and scientific literacy of Indigenous students.
