To assess the current connections between the Unemployment Insurance (UI) and One-Stop (OS) systems, case studies were conducted of eight states and eight local areas. Findings indicated the major factor that influenced UI's role in the OS design was whether the state took initial claims by telephone or in-person; UI played differing roles in financing OS systems; UI's role in managing OS centers was strongly influenced by the extent of UI presence in the center; sites used three strategies to directly link claimants to reemployment services (integrated intake, coordinated intake, and staff-assisted linkages); states had various ways in which claimants made connections at each stage of the UI claims process (initial, continuing, eligibility review, and adjudication); states provided connections from reemployment services to UI; OS systems used UI tax auditors and other staff to market OS services to employers; UI programs used OS services and facilities to enhance UI employer services; and factors that affected connections between UI and OS employer services were time constraints, UI state-level attitudes, attitude of OS management, specialized employer staff and contractors, and location of UI staff. Sixteen recommendations were made to improve connections between UI and OS systems. (YLB)
