The Supporting All Students Act establishes two major mental health initiatives for young people. First, it requires the federal government to maintain a 24/7 peer-to-peer support line for youth experiencing stress or mental health challenges, staffed by trained young peers and supervised by licensed mental health professionals. This support line would operate through voice, text, and chat and integrate with the existing 988 Suicide and Crisis Lifeline. Second, the bill creates a competitive grant program for school districts to hire mental health coordinators who can work alongside licensed professionals to identify struggling students and connect them with school and community mental health resources. The grants will prioritize school districts serving high-poverty communities. Both programs are authorized to receive federal funding through 2029, with no specific funding amounts specified in the legislation. The bill is designed to expand mental health support for school-age youth and young adults across the country by leveraging both peer support and school-based intervention.
