The computer-based System of Interactive Guidance and Information (SIGI) was field tested and evaluated at five community colleges and one university. Developed by Educational Testing Service, SIGI assists students in the process of informed and rational career decision making. Interacting at a cathode-ray tube terminal with a computer, students examine their values, retrieve relevant information about occupations, obtain predictive data, formulate plans, and learn decision making strategies. Adopted as an integral part of the career guidance and planning program at the field test colleges, SIGI ran smoothly, was received enthusiastically by students and counselors, and proved effective in increasing students' mastery of career decision making competencies. This summary report briefly describes the research design and findings of the evaluation. (Author/BW)
