WorkFirst, Washington State’s implementation of Temporary Assistance for Needy Families (TANF), began in April 1997. TANF is a major change in how the state assists low-income families. The program helps parents look for work and provides employment-specific training and basic education opportunities. A number of independent analyses have attempted to estimate employment, earnings, and other outcomes directly attributable to the overall program or to specific program activities, such as Job Search, Community Jobs, Customized Job Skills Training, and Post-Employment Services. This report summarizes the key findings of these analyses.
