A survey of 145 postsecondary programs for hearing-impaired students in North America gathered data pertaining to attrition rates. Estimated attrition rates were found to be lowest for the group of programs primarily offering diplomas, with a rate of 59 percent, and highest for those offering Associate degrees, with a rate of 79 percent. Open-ended interviews were conducted with 20 students who transferred from a mainstream postsecondary program to the National Technical Institute for the Deaf. Three reasons were identified to explain the students' withdrawal from their first college: inability to communicate with teachers, inadequate support services, and limited opportunities for social interaction with peers. It is concluded that accommodations to meet the special needs of hearing-impaired learners may not be adequate to ensure their graduation, and a reason for the high rates of attrition may be a lack of social and academic integration of hearing-impaired students into mainstreamed college life.
