Limits use of smart phones in public schools; requires board of education to establish policy concerning use of smart phones.

New Jersey's S 4274 requires every public school board to create a policy restricting smartphone use during school hours. The policy must ban non-academic smartphone use in classrooms but allows exceptions for medical or transportation needs. It applies directly to students and school boards, mandating clear rules for device use during instructional time. The law takes immediate effect without a delay period.
