With states increasing their focus on supporting successful educational outcomes for students and developing strategies to meet workforce demands, examining data that connects from a student’s early education years to their postsecondary education can allow states to analyze the data in a different and more complex way. However, the structure of data systems and the policies regarding these systems can vary from state to state, with some states not yet having established a Statewide Longitudinal Data System (SLDS).

This new 50-State Comparison: Statewide Longitudinal Data Systems from Education Commission of the States provides a national comparison of how all 50 states plus Washington, D.C., approach policies related to SLDS.

“As states tackle complex policy issues spanning the P20W spectrum – early learning, K-12, postsecondary and workforce – longitudinal data plays a vital role in informing educational policy,” said Brian Sponsler, vice president of policy at Education Commission of the States. “This 50-State Comparison can serve as a comprehensive resource to policymakers as they look to address issues specific to their state through data analysis.”

Some key takeaways from this report:

  • All 50 states plus Washington D.C., have the ability to connect data between systems.
  • Thirty-eight states plus Washington D.C., connect data between at least two of the four core systems – early learning, K-12, postsecondary and workforce.
  • Seventeen states plus Washington D.C., have a full P20W system – a data system that connects data from all four core agencies (as defined in this comparison) across the education spectrum.
