All aspects of a five-week field test of the Information System for Vocational Decisions (ISVD) are reported. Sixteen students were involved; each averaged 3.5 sessions with the system. Results indicate that the most frequently accessed script was the Occupational Preference Script. Nearly half of the students (seven) accessed three data files, and two additional students accessed four files. This correlates with the number of sessions these students had with the system. Case studies for eight of the students who participated in the field test are presented in the following format: (1) use of system; (2) general description; (3) expectations; (4) system activity; (5) reactions; (6) impressions; and (7) general discussion. A variety of outcomes are represented. The appendices contain: (1) samples of the bulletins, letters and forms used in the field test; (2) a copy of the questionnaire for autobiographies together with the responses of the eight case studies; and (3) transcripts of the two final group evaluative sessions.
