This report is part of a wide-ranging programme of quantitative and qualitative analysis, entitled The Learning Curve. It seeks to further our understanding of what leads to successful educational outcomes – both economic and social. The design and execution of the programme has benefited from the ongoing advice of some of the world’s leading educational scholars.

It outlines the main findings from analysis of a large body of internationally comparable education data – The Learning Curve Data Bank.  It also draws on extensive desk research, as well as in-depth interviews conducted with 16 experts in education.
