This guide is intended to assist counselors by providing occupational information about high-technology careers and by providing background information about high technology and its potential impact on the entire occupational structure. The first chapter defines the term "high technology" and includes an overview of how technology is affecting all occupations. In the second chapter, personal accounts of technicians involved in the fields of science, engineering, and technology are provided along with a description of the levels of preparation required for four high-technology careers. The third chapter examines the kind of educational preparation that is currently recommended by many employers and educators for high-technology technicians. Included in the fourth chapter are 36 suggested career education activities with a high-tech content that are keyed to general guidance objectives, a discussion of future trends that promise to influence career guidance professionals, and an assessment of the problems and possibilities of computer-assisted guidance. The final chapter lists sources of labor market information and resources for career guidance in high technology. Appendixes to the guide include a description of a course on principles of technology, a working model for pretechnical studies, charts and illustrations, resource addresses, and sample letters for use in conducting a high-tech career information search.
