Examining Part C Exiting Data Variation

This white paper explores the variation among Part C Exiting categories as reported by the 50 states and Washington, D.C., using 2012-13 exiting data. Examining factors that may contribute to variation can lead to improved Part C Exiting data quality within and across states. Examination of the Part C Exiting data shows that 8 of the 10 categories (categories 1, 2, 4, 5, 6, 8, 9, and 10) had relatively wider variation among states. The paper investigates state characteristics that may influence exiting data variation, as well as possible strategies for improving data quality.
