In order to determine problems encountered and factors relating to successful attendance of deaf students at regular colleges, a self administered questionnaire was mailed to 992 persons. The 653 usable responses were divided into five groups for comparative analysis: Group A, those who graduated from a regular college (224); Group B, those who did not graduate (131); Group C, those still in college (161); Group D, those who transferred from a regular college to Gallaudet (39); and Group E, those graduates of Gallaudet who later attended regular graduate schools (98). Subjects in Groups A and E were highly successful in terms of academic and professional accomplishments, were in professional occupations, and were well adjusted in their marital and social lives. Groups B and D's lower grades in college than Groups A and E seemed to be the major factor in termination or transfer to Gallaudet from regular colleges. In contrast to the graduates, Group C, still in college, used hearing aids more, had more home training and parental encouragement to attend college, and had grades comparable to Group B. Recommendations are given and 79 tables are included. (SN)
