This handbook provides information on effective approaches, methods, processes, and techniques that state and local agencies have used at various stages in implementing their Job Opportunities and Basic Skills (JOBS) programs. It is intended for all state and local agencies involved in planning and providing services to JOBS participants, especially staff at human services, labor, and education agencies. The first section describes types of benefits that can be gained from JOBS coordination. The next section summarizes challenges that coordination efforts may encounter and some of the approaches states and counties have taken. Key elements of state approaches to address specific challenges follow. The next six sections each focus on one of the six specific challenges: (1) overcoming philosophic and programmatic differences among programs; (2) establishing an effective state role in promoting local level coordination; (3) making the most of resources; (4) establishing an effective information exchange; (5) building quality assurance and accountability; and (6) providing appropriate and quality services. Each of these sections consists of a description of the challenge, a summary of state or local approaches, and detailed discussion of the approaches. Appendixes include forms, documents, and guidelines developed by state or local agencies. (YLB)
