The Campbell Collaboration is an international research network that produces systematic reviews of the effects of social interventions in crime and justice, disability, education, international development and social welfare. Campbell seek to bring about positive social change and to improve the quality of public and private services around the world. We believe that a systematic and rigorous approach to research synthesis improves the knowledge base for decisions on policy and practice. Better-informed choices by policymakers and practitioners lead to better outcomes.
