An update to the 2017 Apprenticeship Guide, the report examines national and regional trends such as the role of pre-apprenticeships linked to Registered Apprenticeships, the emergence of intermediaries that organize activity on behalf of multiple employers and apprentices, and growing interest in youth apprenticeships that start in high school. Employers use apprenticeship as a talent recruitment and development strategy, while apprentices obtain a structured career pathway with wages, industry credentials, and, in some cases, college credits. Apprenticeship integrates on-the-job workplace learning and related training and instruction. It has traditionally been used in the U.S. in construction and the skilled trades.
