This book provides a "work-in-progress" that seeks to capture the micro (direct service) and macro (managerial) perspectives related to identifying evidence for practice within the practice domain of public child welfare. It is divided into two categories; namely, evidence for direct practice and evidence for management practice. In Part I, the articles are categorized in the areas of child welfare assessment and child welfare outcomes. Expanded versions of the chapters can be accessed at www.bassc.net.In Part II, the focus is on organizational issues that relate to evidence for management practice. This section includes an overview of evidence-based practice from an organizational perspective along with evidence related to the experiences of others in implementing evidence-based practice.This book pushes the discussion of evidence-based practice in several new directions regarding: 1) the use of structured reviews to complement the systematic reviews of the Cochrane and Campbell Collaboratives, 2) the process of viewing the call for evidence-based practice as a goal or future vision of practice and evidence for practice provides a more immediate approach to promote evidence-informed practice, and 3) a recognition that evidence-informed practice is part of building agency-based knowledge sharing systems that involve the tacit and explicit knowledge needed to improve the outcomes of social services.This book was published as a special issue of the Journal Of Evidence-Based Social Work.
