This report provides details of the experiences of the 2003 cohort of 15 year-olds of the Longitudinal Surveys of Australian Youth (LSAY) in 2004. Information on this cohort was first collected in 2003 when these young people participated in the Programme for International Student Assessment (PISA), conducted by the Organisation for Economic Cooperation and Development (OECD). A follow-up telephone interview that year collected further information on the cohort. The reference period for this report is 2004, when the age of respondents was 16 years. Information about the activities of the 2003 cohort of 15 yearolds in previous years is available in earlier reports in this series.
