STEP Forward was a voluntary program in San Francisco that aimed to connect low-income job seekers to the labor market by using public funds to temporarily subsidize individuals' wages, known as subsidized employment, with the goal of ultimately increasing permanent unsubsidized employment among this population. STEP Forward offered job seekers opportunities to interview for jobs with private sector employers at weekly job fairs and offered employers temporary wage subsidies if they hired disadvantaged job seekers whom they might not otherwise hire. To test the effectiveness of this strategy and to learn about its costs, the Administration for Children and Families (ACF) in the U.S. Department of Health and Human Services funded a random assignment evaluation of STEP Forward, in which individuals were randomly assigned to a program group that had access to STEP Forward services or to a control group that did not have access to STEP Forward services but could receive other services in the community. A total of 837 adults were enrolled into the STEP Forward study between November 2012 and March 2015. In the first year after random assignment when program group members who were placed in subsidized employment were still receiving subsidized wages, program group members were more likely than control group members to have been employed and had higher average earnings. Impacts on earnings continued into the fourth year, well after the subsidies had ended. This paper presents the one-year costs of STEP Forward, including program services such as job-readiness services and the subsidized portion of wages provided to program group members. It also presents the costs of non-STEP Forward services available to both program group and control group members, which included education, training, and job skills services. This evaluation is part of a larger demonstration called the Subsidized and Transitional Employment Demonstration (STED). In addition to STEP Forward, STED includes random assignment evaluations of six other subsidized employment strategies around the country.
