The Foyer is a well-established model of accommodation and support for young people who are, or are at risk of becoming, homeless. The toolkit we have developed is designed to assist communities in adapting this model. It is intended to give service providers and policy makers an essential understanding of the key components necessary for developing a successful Foyer. The toolkit was developed in recognition of the fact that in order to develop a successful Foyer, one must have clarity about their goals and the program model, as well as a strong grasp of the philosophical underpinnings that guide this work.
