This Toolkit summarises approaches to working with young people to prevent youth homelessness relevant to different points in their lives – pre crisis and post crisis. It is based on the Toolkit provided by the Department of Communities and Local Government to guide local authorities and agencies in the UK in preventing youth homelessness available at www.dclg.gov.uk. However it has been adapted to accompany the DVD Homeless Youth: Early Intervention in the UK produced for the CSEYHP project and to be of more general use in other European countries.
