Public Schools; require school boards to adopt policy on bell-to-bell cell phone prohibition.

HB 673 requires Mississippi public school districts to adopt and implement age-appropriate policies banning student cell phone use during all school hours (bell-to-bell), from the start of the first class until dismissal. The policy must prohibit suspensions or expulsions for violations, mandate storage options (like lockers or backpacks) for phones during school time, and include grade-specific rules - elementary students may not have phones in buildings, while middle schoolers must store them during class. It also bans social media access on school networks except for teacher-directed educational use and requires districts to post policies online. The bill aims to reduce distractions and improve classroom focus through these structured phone restrictions.
