This guide describes common One-Stop Career Center system-building goals and summarizes strategies used by states and local One-Stop sites to further each goal. Part I, Organizing and Governing One-Stop Systems, has these two chapters: Guiding One-Stop Systems: The State Role; and Building Local Partnerships and Governing One-Stop Systems. Part II, Building the Infrastructure to Support One-Stop Systems, includes these six chapters describing each major infrastructure system needed to support One-Stop operations: Developing Appropriate Physical Facilities; Creating an Effective One-Stop Information Infrastructure; Building Staff Capacity; Financing One-Stop Services; Marketing One-Stop Systems; and Measuring One-Stop Performance and Planning for System Improvements. Part III, Designing and Delivering One-Stop Services, addresses issues related to the essence of the One-Stop system-building initiative--how to improve the responsiveness of public work force development services to customers' needs. Two chapters are Providing Transformed One-Stop Services to Individual Customers and Providing Transformed One-Stop Services to Employers. Attachments comprising over one-half of the guide provide, for each chapter, useful examples of written materials developed by different states to support One-Stop implementation efforts. (YLB)
