IMPAQ was under subcontract with Research Support Services (RSS) to conduct two waves of telephone follow up interviews for the Centers for Working Families (CWF) Evaluation Project. The CWF program sought to increase families’ financial stability by integrating services and providing assistance with job placement, financial management and public benefits. The study was funded through a Social Innovation Fund grant that LISC received from the Corporation for National and Community Service and by the John D. and Catherine T. MacArthur Foundation. For this project, IMPAQ contacted approximately 2,500 potential respondents to learn about whether the CWF services help people increase their income and assets and become financially stable. Our role in the project is to provide telephone data collection services to conduct baseline and follow-up telephone surveys. The results of the study informed the work of the Local Initiatives Support Corporation (LISC), which manages the CWF initiative and provides funding and technical assistance to the organizations implementing the CWF model. The results were also used to inform a larger audience, including practitioners, policymakers, government agencies, philanthropic funders, and other interested parties, about the effectiveness of the CWF model.
