The National JTPA Study



The National Job Training Partnership Act (JTPA) Study examines the impact of Title II-A of JTPA on participants’ employment, earnings, and welfare receipt.

Data Summary

The National JTPA Study was funded by the U.S. Department of Labor to evaluate the effectiveness of employment and training programs funded under Title II-A of the Job Training Partnership Act of 1982, which is targeted to serve economically disadvantaged adults and youths.

The sample consists of over 20,000 adults and out-of-school youths who applied for JTPA in 16 local areas across the country between 1987 and 1989. They were assigned randomly to either a program group or a control group. Program group members were eligible to receive JTPA services, while control group members were not eligible for JTPA services for 18 months.

The study compares the subsequent earnings and employment outcomes of these two groups, measured through follow-up surveys and administrative records obtained from state unemployment insurance agencies.
