It is very difficult to directly prove definitively that any individual preventative service can achieve this. A number of factors may be in play that effect outcomes. However there is a growing body of opinion that preventative services that include Support Care as part of a range of provision have helped to reduce overall numbers of Looked After children. Most Support Care services that have been in operation for a number of years can report an 80 - 90% success rate in that children and young people referred have not ended up in full-time accommodation. In the context that most families are being referred for the service at a time when family breakdown is a real threat, this figure is a powerful indication that Support Care does indeed have the potential to reduce numbers in the Looked After population
