The Rebuild America's Schools Act of 2026 establishes a multi-faceted program to enhance public school facilities across the United States. It primarily achieves this through a system of federal grants to states and local educational agencies (LEAs), alongside the creation of new tax credit bonds and the restoration of existing ones. The bill emphasizes long-term improvements, focusing on creating safe, healthy, and high-performing learning environments for students. Title I authorizes $20 billion annually for fiscal years 2027 through 2031 for grants to states, outlying areas, and Bureau-funded schools. States must develop plans detailing how they will use these funds, including providing technical assistance, creating publicly accessible databases of school infrastructure, and establishing regulations for health, safety, and energy efficiency. A state matching requirement is included, though it can be waived for larger appropriations, and states must maintain their proportional investment in school facilities. Grants are awarded competitively to qualified local educational agencies with high numbers or percentages of low-income students and limited fundraising capacity. Priority is given to projects addressing severe health and safety threats or improving digital learning access. Recipient LEAs must develop comprehensive 10-year facilities master plans, consulting with various stakeholders, to outline their strategies for facility improvement, maintenance, and operational spending. Title II introduces School Infrastructure Bonds (SIBs) , a new form of tax credit bond, with a national limitation of $10 billion annually for 2027-2029 . It also restores and expands the Qualified Zone Academy Bonds (QZABs), removing the private business contribution requirement and extending their limitation. Projects financed by these bonds, like those funded by grants, must adhere to certain labor standards, ensuring fair wages for workers. Allowable uses of funds under Title III are broad, covering construction, modernization, major repairs, and decarbonization of facilities. Projects can address energy and water efficiency, indoor air quality, toxic substance reduction (e.g., lead, asbestos), ADA compliance, and instructional space improvements. The bill mandates adherence to modern building codes, energy conservation codes, and green building certifications like LEED, while also requiring the use of American-produced iron, steel, and manufactured products , with limited waiver exceptions. The bill also establishes an Office of School Infrastructure and Sustainability within the Department of Education to advise on state plans and coordinate with other federal agencies. It mandates regular studies and reports on the physical condition of public schools by the Secretary of Education and the Comptroller General. These reports will assess the impact of facility conditions on student health, safety, and academic outcomes, and estimate the cost of bringing schools to a state of good repair. Finally, Title VI provides specific assistance for the repair of school foundations affected by pyrrhotite , a mineral that can cause concrete deterioration. States will receive allocations to award grants to LEAs for future repairs or to reimburse past costs, with a federal share of up to 50 percent. This targeted funding addresses a critical structural issue affecting schools in certain regions, ensuring their long-term safety and stability.
