State of the States: Child Data Elements Linked or in 1 System

Child-level data can be collected and stored in multiple ways. States that have their data in one data system or can routinely link all of their child-level data have greater capacity to address critical policy questions than states that do not.

Individual child-level data elements reside in one system or have been linked.

Electronic surveys were sent to Part C and Part B 619 coordinators in all 50 states, the District of Columbia, the Department of Defense, Bureau of Indian Education, and U.S. territories.
