"Who we are
The Campbell Collaboration is an international research network that produces systematic reviews of the effects of social interventions in Crime & Justice, Education, International Development, and Social Welfare.
We seek to bring about positive social change, and to improve the quality of public and private services around the world. We prepare, maintain and disseminate systematic reviews of research related to education, crime and justice, social welfare, and international development.
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, practitioners, and members of the general public can lead to better outcomes."
