In the past thirty-five years, there has been a dramatic evolution in welfare employment and training programs. During this period, there have been numerous efforts to evaluate the effectiveness of these programs. In simple terms, the welfare reform research and evaluations of the past thirty-five years can be described in three major waves: (1) Work Incentives (WIN) Program evaluations conducted by states and others between the implementation of WIN in 1967 and 1988 when the Family Support Act (FSA) of 1988 was passed; (2) Evaluations of the Job Opportunity and Basic Skills Training Program (JOBS), passed under the FSA, between 1989 and 1996; and (3) Welfare evaluation from the mid-1990s to the present, after enactment of the Personal Responsibility and Work Opportunity Reconciliation Act (PRWORA) welfare evaluations from the mid-1990s to the present. The welfare reform research and evaluations presented in this annotated bibliography focus on the two latter waves of welfare reform evaluation with a particular emphasis on recently completed and ongoing research and evaluation projects.
