A research study at Pasadena City College in 1975-76 evaluated a computer based career guidance program, SIGI (System of Interactive Guidance and Information), designed by Educational Testing Service to assist community college students in improving their ability to make career decisions. Students identified as desiring aid in career guidance were randomly assigned to one of two groups: the control group to receive the traditional vocational guidance testing and counseling, and the experimental group to spend an equal amount of time in career exploration using SIGI. Three student and one counselor questionnaire and student records were used to gather data for use in examining results in relationship to twenty-eight specific criteria. Chi square statistical tests were used to determine whether there was significant difference in the suitability of career choice for students in the two groups. Questions regarding appeal of SIGI to males and females, various age groups, ethnic minorities, and occupational and academic majors were also examined as were program costs and effects of reading ability. (Results for each of the twenty-eight criteria are presented and discussed.) Findings strongly indicated that SIGI students were better prepared to make appropriate decisions about their careers than those in the traditional program. Recommendations were that the program be retained and that a follow-up investigation be conducted in two years.
