Establishes antibullying requirements for school districts

HB 2120 requires Missouri public school districts and charter schools to implement comprehensive antibullying policies. It defines bullying broadly to include physical, verbal, cyber, and electronic harassment that causes fear, disrupts learning, or interferes with educational opportunities. Key requirements include: mandating staff to report witnessed bullying within one school day, banning zero-tolerance disciplinary policies, requiring investigations within ten school days of a report, and providing annual training for staff on policy implementation and student education about bullying prevention. The bill also prohibits retaliation against reporters and mandates specific procedures for notifying parents and addressing incidents, including considerations for self-defense in violent situations.
