Early hearing detection and intervention grants were first authorized in the Newborn Infant Hearing Screening and Intervention Act of 1999, which was incorporated into the Consolidated Appropriations Act of 2000, and signed into law. That law provided federal funds for state grants to develop infant hearing screening and intervention programs. The following year, Congress reauthorized these grants through the Children's Health Act of 2000 (P.L. 106-310) and included provisions related to early hearing screening and evaluation of all newborns, coordinated intervention, rehabilitation services, and research. In 2010, Congress passed the Early Hearing Detection and Intervention Act of 2010, which authorized these programs through 2015.
