A number of industrial and business organisations, large and medium, provide organised training for their employees. The type of training varies depending upon the organisation and its needs. The training may be of the informal learning type of the type of organised instructional programme with in the plant under the supervision of the personnel department or of a special education and training division. As a general rule, the training confined to the acquisition of occupational knowledge and competences needed to increase productivity in the occupational concerned. Some are designed to train and retrain employees in specialised areas of occupations. The programmes include apprenticeship and pre-service job training. A good proportion of the present work force is trained as skilled workers, operators and technicians through the system of training-in-industry. Thought limited in scope and application, the training system can provide much needed occupational knowledge and skils extending beyond the normal institutional system and vocational education and training.
