This mixed-methods study is a collaboration between KCL, University of Newcastle, the University of Liverpool and the National Children’s Bureau (NCB). The ORACLE project has two phases, the first focuses on improving understanding of risks, experiences, needs, and outcomes, and the current state of interventions. The second phase focuses on designing a new intervention to improve outcomes for children, young people, and families. Working with the NCB and King’s Policy Institute, ORACLE looks to inform policy in health, social care, education, and criminal justice sectors.
