Although the first EHDI programs in the United States were established more than 20 years ago, most states/territories are not yet able to document the receipt of essential early intervention services and provide documentation of outcomes resulting from early intervention services. Lacking such documentation, it is unclear whether states/systems are accomplishing the goals of ensuring all babies who are D/HH receive early intervention and minimizing the communication delays typically observed in late-identified children who are D/HH. Establishing an IPA with the University of North Caroline at Chapel Hill will assist CDC EHDI in (1) engaging with Part C early intervention programs; (2) developing strategies to assist state EHDI programs in identifying best practices/models to collaborate with Part C programs to address issues of ensuring the provision and documentation of essential early intervention services; (3) supporting assessment of outcomes among babies who are D/HH; and (4) meeting the requirements of the EHDI Act of 2022.
