Children's participation in child protection has become a burgeoning field of interest for scholars and practitioners in the field of social work, and yet there is no edited volume that weaves together recent international contributions on the topic. This volume fills that gap, beginning with the assumption that children can and should have agency in decisions that affect their lives. Child protection is understood as protection from violence in the family and from violence in wider society. Children and youth may encounter public child protection systems in several instances: during child protection investigations, when children receive support services, during decisions about children's removals from home, and when children are in foster, kin, or residential care. Children may experience systemic violence as a lack of personal and economic security, a lack of access to education, and other factors. This book features pathways to children and young people's collective participation in changing child protection policies and services in multiple countries through examples of participatory research and practices promoting children and young people's participation in child protection. It highlights the change actions and voices of empowered and marginalized children and youth in various international contexts. The global examples featured in this volume can serve as an inspiration for children and youth, children's rights activists, child protection practitioners, students, scholars, and public policymakers to initiate, design, and implement participatory child protection policies and practices.
