This open access volume provides the first-ever comprehensive framework of indicators to measure progress in the implementation of the UN Convention on the Rights of the Child. It analyses the development of thinking in the field of children’s rights on the significance of monitoring, and compiles a set of structural, process and outcome (SPO) aspects of children’s human rights-based indicators, for each article in the Convention. It draws on existing measures wherever possible, and involves wide-ranging consultation with experts in the field, along with 2000 children from 35 countries around the globe. This volume provides guidance on the implementation of children’s rights which will be of value to, among others, the UN Committee on the Rights of the Child, governments, policy-makers, advocates, and academics. The potential to measure the actions of governments in meeting the obligations they signed up to in the Convention provides an important contribution towards accountability to children. The indicators and associated analysis can serve as both guidance on what needs to happen to ensure the realisation of children’s rights and a benchmark against which to assess the impact of government action.
