Twelve papers discussing problems encountered and solutions to them were presented at a symposium which brought together persons concerned with the training of professional mechanical engineers. At Session I, papers covered the need for broadly-based training and engineering practice, training requirements for engineers in the process industries, and the social power and responsibility of the engineer. At Session II, they discussed training in engineering practice in a firm of medium size (3500), training at Imperial Metal Industries, Ltd., and views on training held by the Engineering Industry Training Board. At Session III, descriptions were given of various specialized university courses for mechanical engineers, courses of an Engineering Science type, and sandwich courses. At Session IV, discussion centered on one-year post-graduate courses in Universities, the importance of management in engineering and the need for formalized education and training, and "job-centered" short courses at midcareer, such as those provided at Sheffield University. (Also included are reports of discussion and communications, author's replies, and indexes.) (eb)
