Expands the federal definition of homelessness to explicitly cover people who live in indigenous, rural, or otherwise marginalized communities as determined by the Secretary of Education, and makes small technical edits to existing definition text. Establishes a new competitive grant program that authorizes funding to private nonprofit organizations that serve high-need populations — with a focus on women and children — to support operating costs, outpatient and supportive services, housing relocation and stabilization, and other services the Secretary designates. Applicants must apply to the Secretary, include evaluations of services and housing outcomes, and the Department must provide trauma‑informed technical assistance and help coordinate with federal, State, local, and Tribal programs.
