This document provides guidelines for effectively communicating research findings to policymakers. It summarizes a literature review and interviews with stakeholders on best practices. Key factors that influence if evidence is used in policy include: context of the political environment and audience; establishing links and credibility with policymakers; timing recommendations for the policy process; and presenting clear, concise evidence and recommendations. The guidelines cover framing the problem, understanding the audience, credibility, engaging policymakers throughout, choosing messengers, and design of briefs and presentations. The goal is to produce outputs that policymakers will see, understand and hopefully act upon.
