This final evaluation report is the culmination of a three-year investment of time, energy and resources involving 28 Massachusetts nonprofit organizations: 7 foundations, led by the Boston Foundation, The Massachusetts Department of Housing and Community Development; and Homes for Families which joined with the Center for Social Policy team to conduct 10 focus groups involving 72 parents and individuals who shared their perspectives on homelessness prevention, with the guidance of a consumer advisory board involving six persons who have experienced homelessness. Collectively, we engaged in this evaluation effort because we believed that the outcomes of interventions, practice experience of service providers, and the lived experiences of the families and individuals they served have meaning for improving service practices, changing public policies, and increasing public and private resources to prevent other Massachusetts households from falling into homelessness.
