Assembly Bill 1040 mandates that all public, private, and charter schools in Wisconsin maintain a usable supply of opioid antagonists on-site, ensuring that these life-saving medications are easily accessible at all times. The bill establishes new statutory provisions under sections 118.07 (1c) and 165.88 (3n), which require school boards and governing bodies to comply with this requirement. Additionally, the Office of School Safety in the Department of Justice is tasked with providing grants to assist schools in covering the costs associated with maintaining this supply, with an appropriation of $100,000 allocated for the 2026-27 fiscal year.

The bill also reinforces existing legal protections by providing immunity to school personnel who administer opioid antagonists during emergencies related to opioid overdoses. This legislation aims to enhance the safety and preparedness of schools in responding to opioid-related incidents, reflecting a proactive approach to addressing the opioid crisis within educational settings. The act is set to take effect on September 1, 2026.
