• A student with audiory impairment is one who has been determined to have a serious hearing loss even after corrective medical treatment or use of amplification. 

    Deafness means a hearing impairment that is so severe that the child is impaired in processing linguistic information through hearing, with or without amplification that adversely affects the child's educational performance. 

    Hearing impairment means impairment in hearing, whether permanent or fluctuating, that adversely affects a child's educational performance, but that is not included under the definition of deafness.
