The Overseas Development Institute, as part of its Research and Policy in Development (RAPID) programme, has been looking at the links between research and policy for several years. It is now beginning a process of identifying, developing, distributing and delivering tools, resources and training support that can help researchers access policy processes, with the aim of using their research to contribute to more evidence-based and pro-poor policy. This handbook presents work-in-progress on tools for policy impact, specifically geared towards the needs of researchers. The tools are grouped under the headings Research Tools, Context Assessment Tools, Communication Tools, and Policy Influence Tools.
