The Department of Labor’s Jobs Corps is the nation’s largest residential education and job training program for at-risk youth. Authorized by the Workforce Innovation and Opportunity Act (WIOA), the program serves approximately 60,000 participants per year. This report presents a methodology that creates more accurate estimates of costs for two key WIOA performance measures—cost per enrollee and cost per graduate. The data used to track these costs—and the data used to track enrollees and graduates—come from multiple sources, each used for different reporting and accounting purposes. As a result, the sources account for costs in different ways and aggregate data at different levels. The report details a methodology developed by Insight to address these challenges that will help the program better meet WIOA reporting requirements, result in more accurate estimates, provide transparency to Congress and the American public, and increase the efficiency of the reporting process.
