State Longitudinal Data Systems: How are the connections structured?

State Longitudinal Data Systems: How are the connections structured?

October 2016

Education Commission of the States identified two main approaches states use to connect their data: centralized systems and federated systems. We classified state data systems that collect, retain, and maintain data from multiple agencies in a centralized warehouse as “centralized” systems, and state data systems where data from participating agencies was linked temporarily or on an “as needed” basis only as “federated” systems.
