How can we increase the policy impact of evaluation findings?

Voter registration

Evidence from evaluations is a vital ingredient for policy and programme decision making. However, ensuring evaluations are used by the right people in the right way for the right purposes is not straightforward at all.

Researchers need to go beyond just making evidence available and instead they need to take on a broader role of engaging with decision makers throughout the research process to support the use of their research.

This toolkit is designed to support evaluators and researchers who are committed to engaging with decision makers to see the evidence from their studies used to build better policies and programmes.

Navigate the maze of complexity

Case in point: Researchers discuss the policy influence of their impact evaluation

Can giving free bikes get more girls to stay in school? The International Growth Centre sponsored researchers to investigate the effect of providing every schoolgirl aged 14 in Bihar, India, with money to buy a bike.

This short film presents their research and tells a compelling story of the influence it has had in Bihar.

Case in point: Happy endings for Mozambican preschoolers

In 2007, Save the Children partnered with the World Bank on a three year study, funded in part by 3ie, to show the benefits of early education over time, by comparing children in preschool programs with children who were not enrolled.

In this blog, Melissa Kelly describes how Save the Children, together with a range of partners, were able to support uptake of evaluation findings and influence policy makers throughout the evaluation process.

Case in point: Evaluating vocational schools in rural China

Vocational schools are increasingly viewed as an appealing alternative to academic high schools in rural China. In recent years, the Chinese government—at both the local and national levels—has been encouraging students to attend vocational schools. But is this a good thing for students?

With little evidence on the quality of vocational education in China, REAP set out to evaluate the vocational education programmes.
