The bill establishes a competitive grant pilot program to support specialized foster care for larger, diverse, and complex sibling groups. The program aims to provide funding to eligible entities, such as state agencies and nonprofit organizations, to develop evidence-based and effective foster care programs for groups of three or more siblings, those with varying ages, or complex needs. Applicants must demonstrate how the grant will help place and support these sibling groups and provide data on the challenges they face. Grant recipients must submit reports on the program's outcomes and methods used. This initiative is authorized to receive up to $10 million over a 5-year period and will be overseen by the Secretary of Health and Human Services.
