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.

This bill (A4238) prohibits New Jersey school districts from banning active or retired law enforcement officers or registered security officers from carrying firearms while performing school security duties, provided those officers are authorized under state law to carry. It directly affects school districts that hire such officers (including "safe schools resource officers" or Class Three special law enforcement officers) and the officers themselves. The key provision requires school districts to allow these authorized personnel to carry firearms in school buildings or on grounds during their assigned security duties, overriding any existing restrictions. The law takes effect immediately upon enactment.
