This guide, published by the Overseas Development Institute (ODI), was a result of a project designed to build capacity for science communication at the Vietnamese Academy of Social Science. It draws on international good practice and discusses how three tools — the policy brief, the research brief and the story of change — can be used to communicate research through print media. The guide presents case-studies that illustrate policy processes in Vietnam; describes the principles and process of communication, and offers advice on how to write effectively and how to develop policy briefs. The guide is presented as a 'working document' that will be revised to incorporate users' views, and stresses that practice is the best way to improve writing skills.
