Abstract :
Several types of commercial organizations play significant roles in the continuing education of engineers and other professional personnel, supplementing the efforts of individuals, employers, professional societies and universities. In addition to the publication of textbooks and technical magazines, entrepreneurs are discovering new opportunities in the production and distribution of multi-media "packaged" courses. The recent trends toward external degrees and separation of the testing and certification process from the instructional process may enhance the significance of learning opportunities made available through commercial channels.
