In 2024, state legislators introduced hundreds of bills that would affect data collection, access, and use across early education, K-12, postsecondary, and the workforce. As in 2023, legislators continued to introduce and enact legislation governing cross-agency data systems. These policies are the most important step toward making statewide longitudinal data systems (SLDSs)--systems that connect individual-level data over time from early childhood, K-12, postsecondary, and the workforce--more accessible and useful for people. Additionally, new laws nationwide aim to facilitate transitions from high school to college and the workforce, leveraging linked data to make students' journeys more seamless. This resource spotlights significant strides states have made toward enhancing access to data for decisionmaking. Through these legislative efforts, states are advancing their commitment to seamless education and workforce transitions supported by robust data governance, access, and use. Moving forward, continued legislative action is crucial in building and maintaining data systems that provide the necessary information to enable lifelong learning and career success.
