This book explains the background to and effect of the law passed by the National Assembly of Wales, giving general effect to the UNCRC in the exercise of governmental powers, both in terms of furtherance of children's rights in Wales and in terms of its implications for multi-level governance spanning the local to international laws and structures. It presents studies on several key policy areas where issues of children's human rights are prominent, for example child poverty, special educational needs and health provision, treatment of asylum seekers and traveller communities. It also examines the key issues of accountability and civic participation, including the questions of involvement of children and young people.
