The Pre-Apprenticeships To Hardhats Act directs the Department of Labor to award competitive grants to nonprofit partnerships for developing pre-apprenticeship programs that prepare underrepresented populations for registered apprenticeships in building and construction trades. Eligible partnerships must include equal participation from industry employers and labor organizations, along with support from schools, workforce boards, and community groups, and must partner with sponsors of established apprenticeship programs. The grants will fund training curricula aligned with industry standards, participant assessments, stipends for work-based training, and program evaluations, with the federal government covering 75 percent of project costs while grantees contribute 25 percent. Programs will receive initial grants for up to three years, with possible one-year extensions for entities demonstrating satisfactory performance, measured by metrics including participant entry rates into registered apprenticeships. The legislation authorizes $20 million in annual funding beginning in fiscal year 2027, with no sunset date specified.
