Guns, knives, and weapons are generally prohibited on school grounds, as provided by school policies and state and federal laws.

Although children in grades 1-12 are generally not eligible for a concealed carry weapon permit, older students on college campuses may be eligible for a concealed carry permit (CCP) in some states—also known as a concealed handgun license (CHL), license to carry (LTC), concealed carry license (CCL), or concealed carry weapon (CCW).

A student’s right to carry a concealed weapon on school grounds may be governed by state and federal laws, as well as school policies.

In New Jersey, firearms, knives, and other weapons are strictly regulated on school grounds. State law prohibits the possession of firearms on any school property or on a school bus, and this applies to all educational levels, including elementary, secondary, and higher education institutions. The law also extends to private property that is being used by a school for school purposes. New Jersey does not recognize concealed carry permits from other states, and obtaining a concealed carry permit within the state is a rigorous process with strict requirements. Even with a concealed carry permit, carrying a weapon on school grounds is generally illegal, with very limited exceptions for law enforcement officers or as authorized in specific circumstances by the school. Federal law also reinforces these restrictions through the Gun-Free School Zones Act, which prohibits unauthorized individuals from knowingly possessing a firearm in a school zone. School policies further outline prohibitions and may impose additional restrictions on weapons on school property. It's important to note that while some states may allow concealed carry on college campuses, New Jersey's laws are more restrictive and generally do not permit students to carry concealed weapons on school grounds.
