sentences:  The agencies in partnership may include children's centres, early years, schools, children's social work services, primary and secondary health services, playwork, and Child and Adolescent Mental Health services (CAMHS).In the past it has been argued that children and families have received poorer services because of the failure of professionals to understand each other's roles or to work together effectively in a multi-disciplinary manner.ECM seeks to change this, stressing that it is important that all professionals working with children are aware of the contribution that could be made by their own and each other's service and to plan and deliver their work with children and young people accordingly.
