Establishes antibullying requirements for school districts

HB 351 requires Missouri public school districts and charter schools to adopt comprehensive antibullying policies that define bullying broadly to include physical, verbal, cyber, and electronic harassment causing fear or disruption. Schools must report incidents within one school day, investigate within 10 days, ban automatic punishments (zero-tolerance policies), and provide annual staff training and student education on bullying prevention. The policy mandates protections against retaliation, requires consideration of self-defense in violent incidents, and specifies responses like parental notification or referrals to child welfare services for severe cases. These requirements apply to all Missouri public schools and aim to create safer learning environments through clear procedures and accountability.
