In the context of a tight labor market with more jobs than workers to fill openings, and as young people increasingly seek alternatives to college, apprenticeships have become more important than ever. While the "earn and learn" model of apprenticeship seems to be the obvious choice to address labor market needs, it remains underutilized because of varying levels of available funding. This brief examines the costs of scaling apprenticeships, how states are advancing apprenticeships with strategic investments, and findings from a study of apprenticeship funding in Colorado. We also make recommendations for sustained federal and state funding to scale registered apprenticeship, including the development of a state-level funding tool.
