This resource from the IDEA Data Center (IDC) explores variation among Part C Exiting categories as reported by the 50 states and Washington, D.C., using 2012-13 exiting data. Examination of the Part C Exiting data show that 8 of the 10 categories had relatively wide variation among states. The paper investigates state characteristics that may influence exiting data variation, as well as possible strategies for improving data quality. Find this white paper in IDC’s Resource Library.
