Synopsis

The Longitudinal Surveys of Australian Youth (LSAY) track young people as they move from school into further study, work, and other destinations. LSAY uses large, nationally representative samples of students at school to collect information about education and training, work, financial matters, health, social activities and related issues. Survey participants (collectively known as a ‘cohort’) enter the study at age 15 years (or as was the case in the earlier cohorts, when they were in Year 9) and are contacted once a year until they are 25 years old. The program provides a rich source of information about young people and their pathways, helping researchers and policymakers make informed decisions about youth policies.

Sampling frame Y95, Y98 – Year 9 students were selected to form the cohorts of the LSAY program. The sample was constructed by randomly selecting two Year 9 classes from a national sample of 300 schools intended to represent state and sector.
Y03, Y06, Y09, Y15 – Students aged 15 years were selected to participate in the Programme for International Student Assessment (PISA), conducted by the Organisation for Economic Co-operation and Development (OECD). The PISA sample is designed to be representative of students across Australia, using state/territory, school sector and region (metropolitan or non-metropolitan) as strata. Students from small states are over-sampled to allow for PISA results to be reported for each jurisdiction. PISA participants are contacted in subsequent years to become part of the LSAY program. 
Year commenced Groups of survey participants are collectively known as a ‘cohort’. LSAY began in 1995 with the Y95 cohort, followed by additional cohorts in 1998 (Y98), 2003 (Y03), 2006 (Y06) and 2009 (Y09). The most recent cohort began in 2015 (Y15). Since 2003, the initial survey wave has been integrated with the OECD Programme for International Student Assessment (PISA).
Commencement sample Y95 – 13,613; Y98 – 14,117; Y03 – 10,370; Y06 – 14,170; Y09 – 14,251; Y15 – 14,530
Intergenerational? NA 
Imaging NA 
Linkage Consent has been sought to link LSAY records to a number of datasets including: National Assessment Program – Literacy and Numeracy (NAPLAN); Senior Secondary subject results and the National VET Provider Collection. Further scoping work to undertake additional linkages is currently underway.
Biosamples? NA 
Ethics approvals or requirements? Y15 – Ethics approval through Australian Institute of Family Studies (AIFS)
