Provides that school district may not prohibit active or retired law enforcement officer or registered security officer from carrying firearm in performance of school security duties if authorized under State law to carry.

S 1683 prohibits New Jersey school districts from banning active or retired law enforcement officers (including safe schools resource officers) or state-registered security officers from carrying firearms in school buildings or on school grounds while performing their security duties, provided those officers are already authorized under state law to carry firearms. The bill directly affects school districts that contract with such officers for security services, removing their ability to impose firearm restrictions during those duties. Key provisions require school districts to allow authorized officers to carry firearms as part of their assigned security responsibilities, aligning with state law permissions. This is a policy change that modifies school district authority regarding security personnel's firearm use, not a procedural or commemorative measure. The bill takes immediate effect upon enactment.
