This support document accompanies the National Centre for Vocational Education Research (NCVER) report "From School to Work: The Role of Traineeships" (ED493902). It contains a comprehensive review of the literature referred to in that report and detailed descriptions and results of the econometric modeling upon which the findings are based. The key objective of the report is to assess the effect of participating in a traineeship during the transition from school to work on individuals' later labor market outcomes. The data used in the analysis come from the 1995 Year 9 cohort of the Longitudinal Surveys of Australian Youth. Data from annual surveys are available for this cohort from 1995 through to 2002, which for the bulk of the cohort equates to the year in which they turned 14 through to the year in which they turned 21. (Contains 15 tables.) [This report was produced with funding provided through the Australian Department of Education, Science and Training.]
