The Urban Institute's Assessing the New Federalism project assesses the ability of states and TANF clients to meet the work participation requirements proposed by the House of Representatives and Senate Finance Committee. After reviewing the range of work participation rates in the states, work activity among TANF recipients, hours worked each week by TANF recipients, and work activity among those with barriers to employment, the analysis concludes that the proposal to increase work requirements may be very difficult for states and TANF recipients to achieve.
