Over the last decade the UK government has been promoting the concept of ‘evidence-based policy’ (EBP). We are constantly asked by our partners in the South about what is happening in the UK regarding EBP and what can they learn from the UK experience. The aim of this toolkit is to identify lessons and approaches from EBP in the UK which may be valuable for developing countries. The approaches and tools presented are based on the assumption that the reader is a progressive policymaker in a developing country, and one who is interested in utilising EBP. The intended audience is made up of policymakers and policy advisers in the public sector, rather than those working within the private sector or civil society.
