The following trade teaching staff is needed: supervisors of the various trades; forewomen to direct the school shops; trade instructors to teach the various groups of students the specialized processes; assistants to attend to minor matters in the workrooms; art teachers, who have had experience in designing for the various trades represented; academic instructors who know the working world practically and can give the students a training which, while helping them in their trades, will broaden their knowledge of and sympathy in the world's work. All of these teachers must not only have had experience in trade, but must continually keep in touch with the methods of the outside market. Unsuccessful trade workers, who often wish to teach, or teachers who know nothing of the needs of trade workrooms, cannot adequately prepare students for specific trade positions. Trade knows what it wants, is a severe critic and an unsparing judge. The trade school, therefore, cannot afford to rely on instructors who would be themselves unsuccessful in the market, for the result would be certain failure in the students. Such specific training requires exceptional knowledge in its teaching force. The usual teacher of manual training knows too little of the ways of the workrooms and is too theoretical in her instruction to be trusted to train workers who must satisfy trade demands. On the other hand, the trade worker, good as she may be in her specialty, seldom knows how to teach. She can drive her group of workers, but she cannot train the green hands to do more than work quickly at one thing. She can make them work, but she cannot make them better workers. When she has orders to turn out, her lifelong training makes her think of the rapid completion of the articles rather than the careful development of the students who are making them. If she is not watched she will choose the girl to do a piece of work who can do it well and quickly (but who does not need this experience), rather than the one who should do it in order to have practice in it.
