This review was commissioned by the Evidence for Policy and Practice Information and Co-ordinating Centre (EPPI-Centre), part of the Social Science Research Unit at the Institute of Education, University of London, on behalf of the Department for Children, Schools and Families (DCSF). It is intended to inform the DCSF about the nature and extent of research literature on school actions to promote community cohesion. This systematic review was published by EPPI-Centre in 2008. Systematic reviews aim to find as much as possible of the research relevant to the particular research questions, and use explicit methods to identify what can reliably be said on the basis of these studies.
