"Many policy and practice initiatives that aim to prevent social exclusion focus on children and young people. This book considers new approaches to understanding the complexities of prevention and how they can inform policy and practice. The authors use evidence from the National Evaluation of the Children's Fund to explore the experiences of children and families who are the most marginalised. They consider the historical context of approaches to child welfare and present a new framework for understanding and developing preventative policies and practice within the context of social exclusion."--Jacket.
