Welfare programs require people to work, but some low-income adults struggle with major personal challenges that make it hard to find or hold down a job. In this summary, Loprest and Martinson recommend both short-term changes to current programs and longer-term efforts through a program for competitive federal matching block grants to states. These grants would support efforts to integrate programs that alleviate barriers to work with employment services and to evaluate these initiatives so policymakers can better understand what works.
