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 Ohio, firearms, knives, and other weapons are generally prohibited on K-12 school grounds, in accordance with state law and school policies. Ohio Revised Code Section 2923.122 makes it illegal to knowingly convey, or attempt to convey, a deadly weapon or dangerous ordnance into a school safety zone, or to possess a deadly weapon or dangerous ordnance in a school safety zone. This law applies to public and private schools and includes a prohibition on carrying concealed weapons. However, Ohio does allow individuals with a valid concealed handgun license (CHL) to keep their firearm locked in a motor vehicle on school premises. As for college campuses, Ohio law gives the board of trustees of colleges and universities the authority to regulate the possession of firearms on their property. This means that while older students with a CHL may legally carry a concealed weapon in other public spaces, they may be restricted from carrying on their college campus depending on the institution's policies. It's important to note that federal law, specifically the Gun-Free School Zones Act, also prohibits the possession of firearms in school zones, with certain exceptions for licensed individuals. Students should always check the specific policies of their educational institution in addition to understanding state and federal laws regarding weapons on school grounds.
