To address key policy and programmatic questions and help improve student and system performance, states must work to link data across the early childhood, postsecondary and workforce (P-20/workforce) spectrum and share this information with appropriate stakeholders. This issue brief highlights current efforts in California, Florida, Indiana, and Texas to inform decisions, policies and practices by using data that are linked across multiple sectors. The lessons and experiences highlighted below are intended to help inform states' efforts to build interoperable data systems able to provide more robust, timely and actionable information to all stakeholders. There is no single way to use linked data; states are finding myriad ways to use these data to best meet their needs. As states continue to innovate around sharing and using linked data, this issue brief will be updated to reflect new developments. (Contains 2 footnotes and 10 resources.)
