This paper describes the procedures and results of a pilot study of a computer-based System of Interactive Guidance and Information (SIGI) which was designed to help community college students make rational career decisions. A number of the important features of the system are summarized in terms of the source of the value dimensions used in SIGI, the source and rating of occupational information, the derivation of regression equations for prediction, and the strategy to reach tentative career decisions. An illustration with a concrete example of a student's response clarifies the complex processes involved. The pilot study was evaluated in terms of: the responsiveness of SIGI to the needs and purposes of students, and the responsiveness of students to SIGI. Further study is required to generalize the results. (CH)
