This article outlines the findings from an Economic and Social Research Council funded research project that investigated the impact of multi-agency working on children and their families. It explored the ways in which young people experience multi-agency working and it investigated whether young people perceive any benefits from a coordinated approach to frontline service delivery. The in-depth, qualitative study focused on a cross-section of five local authorities and collected data through semi-structured interviews with young people and their parents. The study found that where multi-agency working is effectively integrated and where different professional services are streamlined, there is evidence of a positive impact on young people and their families.
