Continuing professional education for teachers, doctors, lawyers, and engineers is examined in terms of its potential for large-scale electronic technology. For each profession, a profile is provided, and current continuing education programs and use of electronics in each field are described. These include satellite projects, in-house and closed circuit television, telecommunication, and computer networks and data bases for research. The findings indicate that the use of electronic technology in professional continuing education will be continued, and probably expanded. (SK/LS)
