In this Washington Post commentary, Robert Lerman and Stuart Eizenstat argue that the U.S. manufacturing sector is poised for a comeback, but faces serious workforce challenges. To avoid squandering the opportunity to sustain a manufacturing resurgence, the U.S. must match the quality and quantity of skills training achieved in many other countries. One way to do this is a 21st-century apprenticeship program. By training youth and adults through a combined work-based learning and classroom instruction program leading to a recognized and valued occupational credential, apprenticeships can increase employment, while insuring a close match between the skills learned and the skills required.
