Requires school districts and charter schools to adopt written policies governing students' use of electronic personal communications devices

SB 640 requires all Missouri public school districts and charter schools to create written policies by the 2026-27 school year governing students' use of cell phones, tablets, and other personal electronic devices. The policies must ban device use during class time, outline disciplinary steps for violations, and include exceptions for emergencies, classroom instruction, or students needing accommodations under federal disability laws (IDEA, ADA, Rehabilitation Act). Schools must publish these policies online, and staff following the policy will be protected from liability. This directly affects students, teachers, and school administrators by setting clear rules for device use in educational settings.
