In 2012, the national non-profit Single Stop USA served more than 32,000 students across 17 community college sites in seven states. At each college, Single Stop acts as an integral partner in the college's efforts to meet the needs of students and their families. It helps introduce the provision of important services such as tax preparation, financial counseling, and benefit access to the college's set of activities, thus transforming the perspective of both leaders and administrators as to what is "possible" for community colleges to provide. Evaluation of this model is critical but, like the program itself, the program's evaluation is in the early stages. In this report, the authors draw on case studies conducted at six Single Stop sites in New York and Miami in order to describe Single Stop's theory of action and how it operates in practice and on-the ground, and they begin to examine the potential benefits and consequences of greater expansion. The authors introduce readers to the college leaders and administrators who integrate Single Stop's services into their institutions, and talk about the experiences of students receiving Single Stop's services. Since no single model will engage with all community colleges in the same way, they also describe how the Single Stop approach varies across sites. Finally, the authors discuss some recommendations for buttressing the existing financial aid system with additional supports, such as those offered by Single Stop, in order to further lift the financial barriers to community college access and success.
