These guidelines have been prepared as advice to Save the Children UK staff on the principles and practice of child rights programming (CRP). They demonstrate some of the practical implications of adopting a rights–based approach to programming work with children. The first part of the guidelines aims to give an introduction to rights–based approaches and to what Save the Children UK means by CRP. This is followed by a section on putting CRP into practice, highlighting the issue of children and young people’s participation. The final section provides guidance on where to look for further material. The guidelines are illustrated by case studies that draw upon Save the Children UK’s programme experience across the world. They aim to demonstrate the challenges and rewards experienced when taking a CRP approach.
