Miami-Dade Community College's Student Telephone Assisted Registration (STAR) system permits students to obtain a listing of their course schedules; register for, add, or drop classes; or get a list of available course sections by phone. In winter 1988, a study was conducted to assess student use of and reactions to the STAR system. Questionnaires were mailed to 2,066 students to determine which STAR services they had used, their preferred method of registering, their reasons for not using the system, the clarity of the STAR instructions, and suggestions for improving the system. Study findings, based on responses from 362 students and STAR usage data, included the following: (1) of the college-wide total of 45,384 credit students enrolled in winter 1988, 11,954 (27%) registered using STAR; (2) 62.2% of the respondents said that they had tried to register, or add or drop classes using STAR; 32.3% had not tried the system; while 5.2% did not know about it; (3) 14.9% of the STAR users had called to listen to their class schedule, and 9.9% had called for a list of open classes; (4) of the respondents who had tried to use STAR, 78.3% indicated that they preferred it to any other registration method, 9.5% preferred the usual on-campus registration procedure, and 12.2% had no preference; (5) roughly equal fractions of Blacks (55.6%) and Hispanics (58.3%) had used the service, but a considerably greater proportion of Whites (72.0%) had used the service; and (6) 75.8% of the students under 20 had tried the STAR service, while only 57.0% of those 30 and over had used the service.
