Since 2016, the U.S. Department of Labor (DOL) has significantly increased its investment in Registered Apprenticeship (RA) as a proven strategy for building a skilled workforce and expanding economic opportunity. A key component of the federal investment in scaling RA adoption nationwide has been implementation of apprenticeship expansion grants to state agencies. This report explores how states have implemented these grants, implementation challenges, and promising practices they have utilized to meet RA expansion objectives. Drawing on RA grant program data, interviews with state RA expansion grant recipients, and state-level documentation, the report highlights key lessons that can inform future efforts to fund RA program expansion and new Registered Apprentice growth. By examining both common themes and innovative approaches, this report offers practical insights for policymakers, practitioners, and stakeholders working to advance apprenticeship opportunities and outcomes nationwide.
