This guide will help CCDF/licensing Administrators assess current licensing data systems and identify needed changes. It explores new uses for licensing data, examines some strategies for dealing with common challenges, and provides additional resources for review and reference. In addition, Appendix A of the guide highlights three States--Iowa, North Carolina, and Texas--describing their current licensing data systems, uses of their data, and recent and planned changes to their licensing data systems in response to the 2014 reauthorization and 2016 final rule. Appendix B of the guide includes tables to help identify gaps between data elements that are currently collected and data that are required to be collected. The tables also include suggestions for possible new data elements. (author abstract)
