This report makes recommendations for a programme of ‘home international’ comparative research into post-compulsory learning, comparing the four home countries of the UK. Such a programme would be timely because the political devolution of 1999 has increased the differences between the post-compulsory learning systems of the four countries. A programme of home international comparative research could help policy makers, learners, practitioners and other stakeholders to understand these differences. It could also exploit the potential for policy learning by comparing the different policy approaches followed in the four home countries. We define ‘post-compulsory learning’ to cover further education, school education beyond 16, work-based learning and adult and continuing education, and to include the interfaces with other sectors. We place our study in the context of wider international comparisons.
