The following are examples of state legislation to build and use statewide longitudinal data systems to improve student achievement and to foster alignment of data between P-12 and postsecondary systems. These examples were taken from the extensive legislative databases maintained by the Education Commission of the States (http://www.ecs.org/ecs/ecscat.nsf/WebTopicViewAll?OpenView&Count=-1) and the National Conference of State Legislatures (http://www.ncsl.org/programs/educ/educ_leg.cfm). As this will be a growing resource, please forward state legislation pertaining to longitudinal data systems to Erica Wiggins (erica@dataqualitycampaign.org).
