This book showcases rights based participatory approaches to policy-making, practice and research with children and youth. Throughout its three parts, the book conceptualises a rights-based participatory approach; showcases constructive and innovative rights based participatory approaches across the domains of research, policy and practice; and interrogates the challenges and complexities in the implementation of such an approach. In recent times, Ireland has been at the forefront of promoting and implementing participatory approaches to policy-making, practice and research focused on children and youth. This edited volume is a timely opportunity to capture previously undocumented learning generated from a wide range of innovative participatory initiatives implemented in Ireland. In capturing this learning, real world guidance will be provided to international policy-makers, practitioners and researchers working with children and youth.
