Millions of children around the globe experience justice problems and legal needs, which are especially acute for children facing other adversities and disadvantages. To this end, this OECD Child-Friendly Justice Framework supports countries in developing a government-wide strategy to strengthen child-friendly practices in the justice system. Building on the analysis of the legal needs of children and challenges they face when confronting justice problems, this framework provides a basis for child-friendly reforms of justice systems, in line with international standards and obligations. Underpinned by a clear child-centric purpose, the framework provides guidance and good practice examples for (1) designing and delivering child-friendly justice services, (2) establishing the governance enablers and infrastructure to support child-friendly services, (3) empowering children and justice system workers to facilitate child-friendly justice, and (4) planning, monitoring and accountability needed to ensure that child justice reforms are effective and sustained.
