The Community Mental Wellness Worker Training Act authorizes the federal government to award grants to community behavioral health organizations to train and certify community mental wellness workers who can provide basic mental health and substance abuse screening and treatment. The program targets organizations serving disadvantaged areas, including neighborhoods with high poverty, unemployment, substance use rates, and communities with large populations eligible for both Medicare and Medicaid. Grantees can use funding to cover worker training, certification, supervision, digital platforms for service delivery, and clinical oversight, with $25 million authorized annually from 2025 through 2029. The bill also establishes a technical assistance center to help grantees implement evidence-based employment practices and requires progress reports to Congress within one year and by the end of fiscal year 2029. Additionally, the legislation extends federal liability protections to participating organizations and their staff involved in the grant-funded programs.
