Increasingly, practitioners and policy makers are demanding research evidence as a basis for funding programs and policies. The application of research to society has undergone several transitions, from a scholarly emphasis on the experimental method to an attempt to disseminate research and contribute to social policy. Policy makers have emphasized accountability and now evidence-based practices. Although developmental scholars should be pleased that policy makers want evidence, scholars need to examine the assumptions of evidence-based programming and continue to refine how evidence should be used to decide which services to fund. In addition, we propose a more collaborative strategy to promote evidence-based policies in general.
