Measuring the returns on investment in tertiary education three and five years after study

This report presents the results of a study of people’s earnings in the years following tertiary study. The earnings of those who used the Student Loan Scheme, and left study between 1997 and 2001, were related to their personal, educational and employment-related industry factors – factors commonly found to influence income levels. The study used a logistic regression model and a bagging technique. This approach was intended to isolate the independent relationship of each factor to earnings. This report extends an earlier study of earnings three years after tertiary study.
