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 Oklahoma, firearms, knives, and other weapons are generally prohibited on the premises of elementary, middle, and high schools, in accordance with state statutes and federal law, specifically the Gun-Free School Zones Act of 1990. This federal law bans the unauthorized possession of firearms in school zones. Oklahoma state law also prohibits the possession of weapons on school property, with certain exceptions for law enforcement and other authorized individuals. As for post-secondary institutions, Oklahoma allows for the carrying of concealed weapons on college campuses under specific circumstances. Individuals who are 21 years or older (or at least 18 years old and a member or veteran of the United States Armed Forces, Reserves, or National Guard) may be eligible for a concealed carry permit, known as a Handgun License in Oklahoma. However, the decision to allow concealed carry on campus is left to the discretion of each college or university, and they may establish policies that restrict or prohibit firearms on their premises. It's important for students to be aware of and comply with both state laws and individual school policies regarding concealed carry on campus.
