HB 3309 Missouri House · 2026 Regular Session

Establishes provisions relating to protest activities

HB 3309 prohibits protests or demonstrations on public school property during scheduled instructional time if they materially disrupt school operations. It directly affects students (who may be marked absent for leaving class), teachers (who could face licensure revocation for facilitating walkouts), and school districts (which risk losing attendance funding for allowing protests). The bill allows discipline only if protests disrupt school work, infringe on others' rights, or violate neutral time/place/manner policies, while preserving students' First Amendment rights for peaceful expression outside class hours. It explicitly prohibits viewpoint-based suppression and protects lawful activities under state/federal law. This proposed bill (introduced February 2026) aims to maintain school order during instruction but retains core free speech protections.
