The General Accounting Office reviewed the Department of Labor's (DOL) implementation of the North American Free Trade Agreement Transitional Adjustment Assistance (NAFTA-TAA) program to see whether the DOL had corrected the shortcomings of the original Trade Adjustment Assistance (TAA) program. (An earlier study had shown that the TAA program had a number of problems: was often slow in reaching workers, was not equally accessible to all workers, allowed the liberal use of training waivers, may not have tailored services, did not provide ongoing support, did not link training with job opportunities, and lacked a system to monitor performance and effectiveness.) An analysis was made of the DOL's efforts to shorten the timeframe for certification, include states in the certification process, broaden eligibility requirements, and tie income support more closely to retraining and eliminate waivers. Data were gathered through discussions with program and union officials, analysis of petitions, and site visits. The evaluation found that the DOL has addressed a number of shortcomings. For example, the DOL shortened its worker certification timeframe to 40 days or less. In addition, the states' added role in the certification process ensured rapid response services for workers who filed a petition. Workers affected secondarily by NAFTA, however, may find it difficult to access benefits because of limited guidance, unclear authority, and a slow and cumbersome funding mechanism. Finally, in implementing NAFTA-TAA, the DOL did not address other shortcomings such as the lack of ongoing support, followup, and performance monitoring.
