In an effort to shift the focus of employment programs from unemployment to reemployment, the U.S. Department of Labor (DOL) is funding the development and implementation of a one-stop employment system. The DOL has largely left states free to design their one-stop systems provided programs have these features: (1) universality, (2) customer choice orientation, (3) designed to operate as an integrated system, and (4) performance driven/outcome based. Federal guidelines also specify that one-stop programs provide customers with information about the full range of services related to finding employment, filing unemployment insurance claims, and accessing job training/education and assessment/counseling. As of February 1996, 54 states and jurisdictions had received one-stop system-building grants (including 16 implementation grants, 28 planning and development grants, and learning laboratory and system building project grants). The one-stop career centers that have been developed thus far reflect the national trend toward service integration as a strategy for implementing systemic change. Among the challenges facing developers/operators of one-stop career centers are the following: acquiring, installing, and operating the state-of-the-art technology required to function as information brokers; developing strategies for interagency collaboration and business involvement; and formulating strategies for assessing diverse training needs and sharing existing resources.
