Four computer assisted systems, demonstrated for a conference on the implications of computer assisted instruction (CAI) for the practice and education of counselors, are described in this report. The systems are introduced in a first part, and include the Information System for Vocational Decisions (ISVD), the Educational and Career Exploration System (ECES), the Program for Learning in Accordance with Needs (PLAN), and the Interactive Learning System (ILS). Each system is then compared with the others using excerpts from the reaction papers of the participants, and further discussion of CAI is presented with topics focusing on the issues, the potential, implications, and recommendations.
