NCHAM is a multidisciplinary center focused on the implementation and improvement of comprehensive and effective Early Hearing Detection and Intervention (EHDI) systems.  Our goal is to ensure that all infants and toddlers with hearing loss are identified as early as possible and provided with timely and appropriate audiological, educational, and medical intervention. NCHAM collaborates with key agencies and organizations, conducts research and serves as the National Resource Center for EHDI.   Resources available on this website include  newborn hearing screening, early childhood hearing screening, audiological diagnosis, and early intervention. Threaded throughout these components are additional key elements—culturally-competent family support, medical home, data management, legislative mandates,  program evaluation and public policy.
