The General Accounting Office (GAO) interviewed national and regional Job Corps officials and conducted site visits to 14 Job Corps outreach, admissions, and placement contractors for two purposes: to determine whether the Department of Labor's (DOL's) policy guidance on Job Corps eligibility was consistent with legislation and regulations and to collect information on contractors' practices in enrolling individuals for the program and in placing them in jobs after they leave Job Corps. Job Corps' policy guidance for 2 of the 11 eligibility criteria was deemed ambiguous and incomplete. Several participant characteristics were found to be significantly related to the likelihood of remaining in the program for at least 60 days. It was recommended that the DOL use those characteristics to design outreach efforts or establish priorities among eligible applicants. (Fifteen tables/figures are included. Appendixes constituting approximately 50% of this document contain the following: information about the study's scope and methodology; the DOL's Job Corps eligibility criteria; the DOL's Capability and Aspirations Assessment Tool; analysis of the relationship between participant characteristics and the likelihood of remaining in Job Corps for at least 60 days, data supporting the reported figures; comments from the DOL; and GAO contacts and staff acknowledgments.)
