In this context, in 2017, the Office of Planning, Research, and Evaluation within the Administration for Children and Families (ACF) at the U.S. Department of Health and Human Services launched the Building Evidence on Employment Strategies (BEES) project. The goal is to evaluate the effectiveness of innovative programs designed to boost employment and earnings among low-income Americans. Intended to build on previous research on the effectiveness of various employment strategies, the BEES project will fund rigorous evaluations of promising programs serving recipients of the Temporary Assistance for Needy Families (TANF) program or other similarly low-income families who are not receiving TANF cash assistance. BEES will prioritize evaluations of programs that serve adults whose employment prospects have been affected by opioid dependency, abuse of other substances, or mental health conditions. In addition, the project has partnered with the Social Security Administration to evaluate employment-related interventions targeting individuals with current or foreseeable disabilities who have limited work history and are at risk of applying for Supplemental Security Income (SSI). Ultimately, the goal of the project is to strengthen ACF’s understanding of evidence-supported programs that are effective in improving employment and economic security. The MDRC-led team includes Abt Global and MEF Associates.
