Professional judgement and decision making are central to social work, both in everyday professional practice and in public perceptions of social work as a profession. This book examines key issues that are relevant today. The chapters cover child protection, mental health, and elder care settings in Europe, Australia and Canada. They discuss organisational and cultural contexts for professional judgement; the role of experience in the development of expertise and professional discretion; understanding variability in decision making; and the role of legal frameworks in decision making. This book will enable practitioners, managers, policy makers, and researchers to appreciate the complexities of professional judgement and decision making in different social work settings and to apply this understanding to their own practice. This book was originally published as a special issue of the Journal of Social Work Practice.The book is linked to sister text Risk in Social Work Practice: Current Issues, which examines key debates around the understanding of risk in contemporary social work practice.
