Requires schools to adopt school policies governing materials that are obscene or harmful to minors

This bill requires Missouri public schools and charter schools to create policies that prevent obscene or harmful materials from being available to students in school libraries or by teachers during instruction. The law defines harmful material as content involving nudity, sexual conduct, excessive violence, or sadomasochistic abuse that appeals to minors' prurient interests and lacks serious value. Under the new rules, parents can report such materials to school administrators, who must remove them for at least thirty days while the school board reviews the content to decide if it should be permanently banned. The bill also updates existing legal definitions to clarify what counts as obscene or harmful in an educational setting.
