High-quality systematic and other research reviews

Cochrane and Campbell Collaborations

The two best sources for high-quality systematic reviews and meta-analyses, with plain-language summaries so results are easily understood by non-researchers.


The Evidence for Policy and Practice Information and Co-ordinating Centre (EPPI-Centre) is part of the Social Science Research Unit at the Institute of Education, University of London. It offers plain-language summaries of evidence reviews on a wide range of topics.


Good research summaries on many topics

What Works Clearinghouse (education programmes)

Hosted by the Institute for Education Sciences, this site compares the evidence for dozens of education programmes.

The EBI Network (education programmes)

Developed to provide guidance in the selection and implementation of evidence-based interventions in the classroom setting.

Blueprints for Healthy Youth Development

Helps practitioners to match children’s needs to cost-effective programmes that have been proven through research. Identifies and rates programmes that meet the highest scientific standard of evidence for promoting youth behaviour, education, emotional well-being, health, and positive relationships.

Center for Evidence-based Crime Policy

Housed within the Department of Criminology, Law and Society at George Mason University (USA), the Center evaluates justice programmes and works to improve communication between research and practice. They provide a useful collection of one-page summaries of crime policy research, with brief explanations of the findings and what they mean for practice.

The Office of Justice Programs (OJP) sponsors as a resource to help justice practitioners determine what works in criminal justice, juvenile justice and crime victim services. The site applies a scoring instrument to help determine effectiveness of interventions.
