This report, which was commissioned by the National Audit Office (NAO) in the United Kingdom, presents results of a comparative study investigating the implementation of education programmes for 14-19 year olds in three countries: The Netherlands, Sweden, and Australia. The main purpose of the study is to identify lessons that could lead to improvements in implementation and delivery of the new 14-19 Diplomas programme. In particular, the study focuses on two aspects of Diploma implementation: local delivery partnerships and employer involvement. The case study reports provide a general overview of each country's secondary education system; processes for implementation and delivery of qualifications; the nature and level of employer involvement; and comparative lessons. In addition, an overarching analysis, which is presented in the final chapter, draws out the principal themes of the comparison between the case studies and aims to identify lessons for 14-19 Diplomas.
