State-based Early Hearing Detection and Intervention Program Network (EHDI)


The State-based Early Hearing Detection and Intervention Program Network (EHDI) programs are located in states and territories. These programs are designed to identify infants with hearing loss and enroll these infants in early intervention programs designed to help them develop communication skills. The EHDI network collaborates with states in the development and implementation of EHDI programs and assists states in building EHDI data an surveillance systems to ensure that all infants are screened for hearing loss and receive appropriate follow-up services. States report results of screenings and follow-up as part of the Annual EHDI survey.
