The STEM Restoring Employment Skills through Targeted Assistance, Re-entry, and Training Act, or the STEM RESTART Act , proposes to amend the Workforce Innovation and Opportunity Act (WIOA). Its primary goal is to create a new national program designed to support mid-career skilled workers in reentering or transitioning into the STEM workforce. This initiative specifically targets unemployed or underemployed individuals, particularly those from rural areas, by helping them secure positions above entry level. The bill establishes a competitive grant program, known as RESTART grants , for eligible small-sized and medium-sized STEM enterprises or consortia. These grants, ranging from $100,000 to $5,000,000 annually depending on business size, will fund high-quality, paid internships or "returnships" lasting at least 10 weeks. These opportunities must provide compensation and benefits comparable to full-time employees with equivalent experience, and lead to full-time careers with pathways for advancement. Grant funds can cover participant education, training, equipment, travel, housing, mentorship, and salaries, as well as supplement compensation for existing employees supporting the program. Entities receiving grants must coordinate with State workforce boards and submit annual reports detailing participant demographics, employment transitions, and internship conversion rates. The Secretary of Labor is mandated to evaluate this data, report best practices to Congress, and make this information publicly available. The bill authorizes $50,000,000 annually for fiscal years 2026 through 2030 to carry out these provisions.
