To provide guidance to state workforce agencies responsible for administration of the federal-state Unemployment Insurance (UI) programs on provisions of the Workforce Innovation and Opportunity Act (WIOA) related to UI, and to: 1) recommend that state UI agencies continue to work with other workforce partners in the development and implementation of strategies that support the WIOA vision, as described in Training and Employment Guidance Letter (TEGL) No. 19-14; 2) encourage State and Local Workforce Development Boards to consider how to most effectively leverage federal-state UI programs, including the Reemployment Services and Eligibility Assessment Program (RESEA), as they implement integrated service delivery strategies through American Job Centers under WIOA; and 3) clarify the requirements and methods for UI to make financial contributions towards WIOA infrastructure costs.
