This legislation, titled the "Runaway and Homeless Youth and Trafficking Prevention Act of 2025," reauthorizes and significantly updates the existing Runaway and Homeless Youth Act. It revises congressional findings to acknowledge the complex challenges faced by homeless youth, such as trauma, substance use disorders, and the disproportionate impact on historically marginalized communities, including LGBTQ youth and youth of color. The bill emphasizes the critical need for services that are culturally and linguistically appropriate, age- and gender-sensitive, and grounded in a positive youth development approach. The bill extends grants for both the Basic Center Grant Program and the Transitional Living Grant Program to five-year terms, ensuring more stable funding for local centers. These programs are now explicitly required to offer trauma-informed services, suicide prevention, and support for youth who are victims of trafficking. Grant recipients must collect detailed demographic data, including information on trafficking victims and youth involved with the child welfare or justice systems, while maintaining strict confidentiality. A key provision mandates that programs inform youth of their status as independent students for federal financial aid purposes and assist them with the Free Application for Federal Student Aid (FAFSA). Services provided under these grants must consider the youth's age, gender, and social and developmental needs, ensuring they are culturally and linguistically appropriate. The legislation also encourages the use of online resources and social media for outreach to engage more eligible youth. A new Prevention Services grant program is established, offering additional, optional funding for successful basic center or transitional living programs to proactively prevent youth homelessness and running away. The Street Outreach Program is specifically enhanced to provide street-based services to youth at risk of or subjected to sexual abuse and trafficking. The bill integrates anti-trafficking measures throughout the act, including in data collection, training, and the definition of "trafficking" itself. The legislation introduces a new waiver authority, allowing the Secretary to temporarily waive certain provisions in extraordinary circumstances like natural disasters or public health emergencies, to improve service delivery without compromising youth safety. It also establishes a clear Nondiscrimination policy, prohibiting discrimination based on actual or perceived race, color, religion, national origin, sex, gender identity, sexual orientation, or disability. Finally, the bill significantly increases funding authorizations across all parts of the Act, with specific allocations for basic centers, transitional living, street outreach, and the new prevention services.
