Tennessee SB1418 establishes the "Tennessee Mental Health Volunteer Alliance Act," which requires the Department of Mental Health and Substance Abuse Services to create a statewide volunteer database of qualified mental health professionals to provide immediate mental healthcare services in schools or public facilities following gun violence or significant traumatic events. The bill affects mental health professionals, schools, and public facilities, detailing provisions for a volunteer application process, funding for administrative costs, and the creation of a school safety fund for purchasing safety technology. It also mandates annual reporting on expenditures from the fund to the relevant legislative committees.
