The development of a counseling system designed for a small computer, although limited in both scope and objectives, appears to be practicable and economical. Described herein is a program intended to perform some of the functions performed by a counselor. It is merely a tool to be used by counselor, not a replacement for him. The program described applies to vocational counseling. Keeping data current is simplified by using a computer. The main object of such a program is to promote the decision making ability of the student by making information available to him, and by giving him the opportunity for vicarious experiences in making occupational choices. A total of three precise tasks in the design of this exploration system are indicated: (1) the development of interest categories; (2) the development of categories of educational aspirations; and (3) the classification of a given set of occupations in terms of the specified interest and educational categories. The system may then be used by students or counselors in any of three modes: (1) exploration, (2) index, or (3) guidance. This program has been implemented on a DEC TSS-8 system, for reasons described in another paper. It is being used in the Faculty of Education, The University of Calgary. (KJ)
