Combining data from the Longitudinal Surveys of Australian Youth (LSAY) with external sources has improved the breadth of information available from the survey alone. However, linking to survey data presents several challenges, including the need to obtained consent to undertake the linkage.

This technical paper demonstrates reliable assessment data across several learning domains is possible through data linkage and allows for analyses on how academic achievement across multiple stages of schooling influences a young person’s life course.
