Changes to the welfare system brought about by the Personal Responsibility and Work Opportunity Reconciliation Act (PRWORA), and state and local welfare reform efforts, carry serious implications for Temporary Assistance to Needy Families (TNF) recipients with disabilities and barriers to employment. Specifically, work participation and time limit requirements are two key provisions of the federal welfare law which provided a new sense of urgency encouraging states to develop strategies to assist clients with their transistions from welfare to work. As a first step in this process, TANF agencies are considering strategies to identify the barriers that are inhibiting or prohibiting this transition. PRWORA offers unprecedented flexibility to develop such strategies and design programs and services to assist with the transition from welfare to work. This paper is merely a first step in considering some of the many challenges associated with identifying unobserved barriers to employment.
