The Longitudinal Surveys of Australian Youth (LSAY) is a survey program that tracks groups of young Australians with the aim of studying their transition from school to further education and work. It uses large, nationally representative samples of young people to collect information about education and training, employment and social development.

The LSAY program brings together two existing, long-established projects: the Youth in Transition survey conducted by the Australian Council for Educational Research, and the Australian Youth Survey conducted by the former Australian Department of Education, Employment, Training and Youth Affairs.

Survey participants (collectively known as a 'cohort') enter the study when they turn 15 years old, or as was the case in earlier studies, when they were in Year 9. Individuals are contacted annually until they are 25 years of age. Studies began in 1995, 1998, 2003, 2006, 2009 and more recently in 2015. About 14,000 students start out in each cohort. Since 2003, the first survey wave has been integrated with the Organisation for Economic Co-operation and Development (OECD) Programme for International Student Assessment (PISA).

Further information about the LSAY program is available from the LSAY website.
