In honor of National Apprenticeship Week, and to help businesses understand the benefits from apprenticeship, the U.S. Department of Commerce is releasing a beta version of a return-on-investment (ROI) calculator. Apprenticeships allows workers to learn skills on-the-job while earning a paycheck and graduating with an industry-recognized credential, and often an academic degree or credits as well. Registered apprenticeships have an 80-year history in the United States, dating from the National Apprenticeship Act. Since then apprenticeships have been focused on preparing workers for critical construction jobs in our economy. As outlined in the Executive Order Expanding Apprenticeships in America, our country needs to apply lessons learned from that tradition to develop skilled workers for many other sectors where apprenticeship is well suited but only in its infancy.
