Popular discussions of industrial training are rendered difficult by the fact that the subject has as yet no fixed vocabulary. Professional training, vocational training, industrial training, manual training, are often used interchangeably. We shall use the phrase “vocational training,” and shall understand it to include such education as aims to secure efficiency in the occupation followed for self-maintenance, whether such occupation be the merest task or the complex administration of a business or a profession. It is evident that such training involves education for general intelligence, as well as technical training with a specific end in view. It is also clear that the training may be brief and elementary if the task is simple; the trade school, or apprenticeship, or even the brief course of lessons given by another worker may suffice where the work calls for little skill and involves little variety. As the task grows in difficulty, requiring application of principles, demanding judgment, broad experience, ability to deal with and to direct others, the training must be proportionately increased. The demand for general intelligence also grows correspondingly. The instrument for vocational training, then, may be the shop, in which knowledge of the art is handed along from one worker to another through simple apprenticeship; or the trade school, in which a brief course of instruction is given, with emphasis upon technical details and swiftness of accomplishment; or the technical college, which provides longer courses of instruction, combining academic and technical programs, alternating the lecture room with the shop; or actual apprenticeship in business; or professional training, superadded to the ordinary program afforded by school and college. Is vocational training necessary for women? As a matter of fact, women are already in trades and professions. For years they have been filling our factories, stores, offices and schools. We have made public provision for the preparation of teachers, and many states likewise train women for the practice of medicine. Hospitals have provided training schools for nurses. In these fields some provision has been made for the appropriate education of women for their work. Enough experience has been accumulated to show that training for the vocation is always beneficial, and usually essential. The ordinary woman, however, has little specific training for the most important work which she has to do in the world. It is left to her mother alone to teach her how to maintain her home and to meet the needs of her children. If the mother is ignorant, the daughter is untaught, and a long train of evils follows in consequence. As this matter concerns the general welfare the evils should be prevented, if possible, by general education.
