About Accommodating a travelling life (ATL) project is framed within the need of offering innovative and effective solutions to persons who find themselves living in the street. With this project, we will help organizations working in the field to conduct more effective interventions with persons living in the street by involving persons with first-hand experience in the intervention process. For that purpose, ATL introduces the figure of Journey Certified Supporters (JCS)- mutual support agents with lived experience of homelessness, advanced in their process of re-integration and trained in the ATL methodology. ATL project will design a tailor made training model built on the principles of peer support methodology. It will provide training to both professionals and experts by experience to prepare the latter to become Journey Certified Supporters. Comprehensive information and a set of effective training tools will help the future JCS to give value to their life experience and use it to help homeless people to get out of the situation of extreme vulnerability and social exclusion. On the other hand, the ATL training program for professionals will prepare the latter to offer tailored support and conduct interventions in coordination with the JCSs. ATL methodology will incorporate the Restorative Justice approach with the objective of contributing to the reestablishment of family and friendship ties and thus favoring re-integration. It will address the recovery of homeless people from a respectful, unconditional approach, based on listening and dialogue, which does not judge or criticize.
