The Adult Education Coordination and Planning (AECAP) guide is designed to assist state adult education staff in forming partnerships at the state level and facilitating coordination at the local level as a lever for expanding and improving the quality of adult basic education (ABE) and workforce development services. Coordination plays a critical role in the operation of the adult basic education system at the state and local levels. The processes discussed in this guide are intended to assist state adult education staff in establishing new or expanding existing state partnerships to address issues of common concern, particularly those related to the coordination of services supported under WIA Title I and Title II. Planning is a critical step in developing coordinated adult education services. The first section of the guide presents the steps in the AIDDE[C] planning process, which can be used by ABE state staff in working with state partners to address a common need or issue, such as increasing client outcomes. This section also highlights key strategies for partners to use in strengthening and sustaining their relationships. Worksheets are provided in Appendix A for state partners to use in planning their activities. Implementing a state initiative is one strategy that state adult education staff may consider to focus attention on a critical issue in a state and to test the development of new services to address this issue. The next section of the guide describes the key steps that state adult education staff can use alone or with state partners to implement a state initiative. The final section of the guide provides steps for planning coordinated local services as part of a state initiative or pilot test. The AIDDE[C] process can be used by ABE state and local staff working together to identify and plan the activities that local staff will carry out as part of the pilot test. A worksheet is provided in Appendix B for use in this process. Also discussed are examples of the coordinated services that were developed by the AECAP pilot sites. These examples are illustrative of the types of services that ABE state and local program staff may consider to address goals such as increasing the number of ABE clients who transition to postsecondary education, training, and work and promoting the delivery of quality ABE services.
