Assembly Bill 156 mandates that, starting in the 2026-27 school year, all school boards in Wisconsin must implement a child sexual abuse prevention instructional program for students from 4-year-old kindergarten through grade 12. The program must cover a range of topics, including age-appropriate facts about sexual abuse, how to communicate incidents to trusted adults, setting and respecting personal boundaries, and understanding consent. Additionally, before the program is offered, school boards are required to inform parents or guardians about the program's content, schedule, and the process for opting out.

The bill also stipulates that parents or guardians can exempt their child from the program by submitting a written request to the child's teacher or principal. The instructional program must be developmentally appropriate and evidence-informed, ensuring that students receive relevant education tailored to their grade level. The legislation aims to equip children with the knowledge and skills necessary to recognize and prevent sexual abuse, while also involving parents in the educational process.
