This report provides key findings from a study of two juvenile justice systems, Snohomish and Kitsap counties, in Washington to develop a court-based strategy to prevent youth homelessness. The development team conducted this study in response to the high rate (75 percent) of homeless youth who have contact with police, with more than 50 percent experiencing arrest. They developed the Youth Housing Stability (YHS) model to minimize this contact while providing youth needed supports and services to remain housed. The development team designed the YHS model to address both system-wide and program-level needs to prevent housing instability for an estimated 100 to 150 youth within each jurisdiction each year. In addition, this model helps build community capacity for effective prevention through the implementation of services accessible to youth referred by non-court agencies. (author abstract modified)
