Book excerpt: Significant amounts of money and resources are spent on child and family services, so successful evaluation of whether or not they are achieving the best outcomes is therefore essential. This edited collection offers an international perspective on the challenges of designing and undertaking outcome-based evaluation of child and family services. With contributions from leading international experts, it introduces the key ideas and issues currently being debated in the evaluation of these services; discusses relevant approaches to designing and using evaluation methods; and provides examples of evaluation from the real world of policy and practice. Issues covered include setting appropriate indicators for service effectiveness, cross-cultural evaluation of service interventions, service user involvement in evaluation, and evaluations of family and community-based services. This invaluable book will be essential reading for policy makers, planners, commissioners and managers across child and family welfare services, as well as researchers and other academics in the field.
