The ‘Community of Schools and Services’ (COSS) Model of Early Intervention: A System-Changing Innovation for the Prevention of Youth Homelessness

Prevention and early intervention have become part of the Australian policy discourse; however, the prevention and early intervention of youth homelessness remain significantly underdeveloped and underfunded in practice. Consequently, too many young people experience homelessness. This article presents the ‘Community of Schools and Services’ (COSS) Model as an innovative approach to the prevention of youth homelessness. The COSS Model is an Australian place-based collective impact approach that uses data gathered via population screening in secondary schools to identify and then support adolescents at risk of homelessness and also reorganizes the local support system available to vulnerable young people and their families. This paper is not the result of a research project. Rather, this paper presents the findings of the Embedded Development and Outcomes Measurement (EDOM) report, which is a feature of the COSS Model. This paper is limited to findings from the COSS Model implementation in Albury, NSW, known as the Albury Project, from 2019 to 2023. The Albury Project has demonstrated significant reductions in the risk of homelessness and entry into the local homelessness service system. Findings reveal that: (1) when COSS Model support is delivered to identified at-risk students, 40–50% of individuals are no longer at such high risk of homelessness 12-months later; (2) only 3–5% of students identified as at risk of homelessness and supported through the COSS Model sought assistance from local homelessness services in the following two years; and (3) the flow of adolescents (12–18 years) into the local homelessness services was reduced by 40% from 2019 to 2023. As an evidence-based, complex innovation, there are major policy, funding, and implementation challenges in scaling the model to multiple community sites.
