The Annual Survey of Hearing Impaired Children and Youth (1971-72) obtained information on 42,513 students enrolled in 636 preschool, elementary, and secondary educational programs for the hearing impaired. Data were gathered on the number of hearing impaired students with additional handicapping conditions, the types of conditions reported, the severity of the conditions, the profession of the person who evaluated the conditions, whether or not the student was receiving medication, ethnic origin, and degree of hearing loss. The data indicated that 32 percent of the students had one or more additional handicapping conditions, that a greater proportion of males had additional handicapping conditions, that students with hearing threshold levels below 65 decibels were slightly more likely to have additional handicaps, that students whose hearing loss was present at birth were more likely to have additional handicaps, and that most frequently reported types of additional handicapping conditions were emotional or behavioral problems, mental retardation, and visual disorders.
