This paper describes the use and challenges of microcomputers in guidance and counseling. Following introductory remarks on the technological advancement of computers and their impact, currently available career guidance systems, testing systems (including psychological testing, interviewing, and test preparation), administrative systems, and personal counseling systems are itemized. Each listing contains a brief annotation and the microcomputer for which the software is designed. Issues which have been raised by the growing attention to the use of microcomputers in counseling are discussed, including quality of programs, cost, theoretical assumptions, context of use, approach-avoidance behavior, confidentiality, and how to get started. Challenges to the profession, (e.g., literacy, knowledge of software, and application designs) are discussed. The paper concludes with proposals for state and national level leadership tasks and roles. (BL)
