This document describes the Joint Tenancy Assistance Program (JTAP), a partnership program that helps homeless young people aged 16-19 who have complex needs and contact with the juvenile justice system in NSW, Australia. JTAP provides housing and support over 4 phases spanning 4 months each to help participants build life skills and independence. The program has been successful, with 39% of participants exiting into priority housing and 67% resuming education achieving at least Year 10. Key elements of JTAP's success include flexibility, a supportive service network, case management, maintaining family connections, limited participant numbers, and a phased progress model.
