This Practice Brief accompanies the International Review of Parent Advocacy in Child Welfare: Strengthening Children's Care and Protection Through Parent Participation. It provides a brief overview of parent advocacy and how it benefits children and families. The brief offers a review of lessons learned from research into the outcomes and effective implementation of program advocacy - in which parent advocates design, plan, evaluate and strengthen programs and assist other parents. The brief outlines some ideas for developing a strategy to promote parent advocacy and points to a few helpful resources, including the Toolkit for Transformation: Building an International Parent-Led Movement Fighting for Families Affected by Child Welfare.
