Apprenticeship is a time-honored method for preparing workers to master occupational skills and achieve career success. Young people reap many developmental benefits from engaging in apprenticeships. It is important to expand the scale of apprenticeship training to increase skills and help more workers enter rewarding careers. Despite substantial benefits, federal support for apprenticeship training is meager. Promoting more apprenticeship training will not only expand the effectiveness of education and training and enhance productivity, but it will also integrate many workers who prefer learning-by-doing and the earning-when-learning aspects of apprenticeship training.
