In 2010, the State Higher Education Executive Officers Association released the results of a national study of state level postsecondary student unit record (SUR) data systems in 44 states and the District of Columbia (D.C.). One section of the report, "Strong Foundations: The State of State Postsecondary Data Systems" (Garcia and L'Orange 2010), included information on the extent to which postsecondary coordinating and governing boards engage in a variety of data sharing practices with state agencies. This 2012 update focuses on those data sharing practices. In addition, the authors shed light on statewide, coordinated, multi-sector data sharing in which the postsecondary sector plays a role. Some states share data via a centralized state P-20 data system, but more states are "building" a federated data model that is more decentralized in nature. Regardless of the model used, there is a substantial and growing amount of statewide, coordinated multi-sector data sharing across the country, much of which likely has been influenced by the U.S. Department of Education Statewide Longitudinal Data Systems (SLDS) grant program. Appended are: (1) List of Respondents by State and Agency/Entity; (2) Data Collection Template; (3) Responses by Question; (4) History of Statewide Longitudinal Data Systems Awardees, FY2006-FY2012; and (5) Abbreviations Used for States with Multiple Agencies/Entities. (Contains 11 figures, 1 table, and 9 footnotes.)
