A study was conducted at Charles Stewart Mott Community College (MCC) to determine why many persons admitted to the college never complete any courses, to identify aspects of the college environment which might be changed to retain some of these potential students, and to learn how to channel recruitment resources toward applicants who are more likely to register. Telephone interviews were conducted with a sample of 241 individuals out of the 754 who were admitted to MCC in 1981-82, but who did not register for courses, in order to ascertain: (1) the admissions and registration procedures completed by the respondents; (2) the reasons the respondents did not register for courses; (3) the courses or programs they had wished to study at MCC; (4) the reasons they applied to MCC; (5) the activities they pursued instead of attending the college; (6) the reasons they would or would not attend MCC in the future; and (7) suggested improvements in college services. The interviews revealed that when applying for admission, 36% of the respondents talked to a counselor and 32% took a placement test. Respondents failed to register for courses primarily because personal or family problems intervened, or because the classes they needed were full or cancelled. Although 16% said they would probably not want to attend MCC in the future, 51% indicated that they definitely would be interested and 33% said they might be. The study report includes suggestions for further research, the survey instrument, and a bibliography. (DAB)
