Interviews with 42 middle-level technical workers in the electronics industry in six Singapore manufacturing companies explored the training they received. Study findings revealed that technical workers carried out various functions across the whole productive process, including product development and industrial engineering, input, the production line, product testing, and back end. Integral related activities included process engineering, maintenance, and quality assurance. The typical technical worker obtained the Technician Diploma or the Industrial Technician Certificate by full-time institutional training, after school and before national service. These workers were probably pursuing an additional formal qualification through continuing education and training, had been sent by the company to an external training program, and/or had been sent on overseas training. The study found that job skill formation required these prerequisites, generally provided by preparatory and off-the-job formal and nonformal training: personal abilities, technical knowledge and skills, and technological know-how and job knowledge. To attain job competence, the worker needed to develop and apply knowledge, job skills, work skills, and accumulated experience. Three levels of jobs were supervisory, technical, and routine. In companies, line management carried out on-the-job training, implicitly rather than explicitly. No company considered apprenticeship. (YLB)
