An increase in provider training, changes and clarifications in Medicaid payment policy, and increased attention to developmental, social-emotional and perinatal depression screening has led to measurable improvements in developmental screening performed statewide in Illinois. The Illinois’ ABCD II Project improved the delivery of developmental services for young children and their families through infrastructure development that largely resulted from policy clarification and changes, provider training, and the implementation of a sustainability strategy.

The Illinois project was supported by grants from the Michael Reese Health Trust, with support also from the Chicago Community Trust during the first year of the three-year initiative.
