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 Colorado, firearms, knives, and other weapons are generally prohibited on the grounds of K-12 schools, in accordance with both state statutes and federal law, specifically the Gun-Free School Zones Act of 1990. This federal law prohibits the possession of firearms within a school zone, which is defined as in or on the grounds of a school, or within 1,000 feet of the grounds of a school. Colorado law also prohibits the possession of firearms on the property of any public or private elementary, middle, junior high, or high school. However, there are exceptions for law enforcement officers and other authorized individuals. As for postsecondary institutions, Colorado allows individuals with a valid concealed carry permit to carry a concealed handgun on the campuses of state colleges and universities. Each postsecondary institution may have its own policies regarding the storage of firearms on campus, but they cannot outright ban permit holders from carrying concealed handguns. It's important for students and all individuals to be aware of and comply with both the state laws and the specific policies of the educational institution they are on.
