Arkansas - in 2013, The Arkansas Legislature passed and the Governor signed into law, Act 226, which provides for faculty at Arkansas’ college and universities to carry concealed weapons. The law contains a major provision – schools can opt out of the law on an annual basis. For the 2nd year, every single 2 and 4 year college has exercised their “opt out” right, effectively keeping concealed weapons off all campuses in Arkansas
Colorado - the Colorado Court of Appeals has ruled twice that under the Colorado Concealed Carry Act (2003), the Colorado Board of Regents does not have the authority to ban concealed carry license holders from carrying their firearms on public campuses (Colorado State in 2010 and the University of Colorado in 2012)
Idaho - March 12, 2014, Gov. Butch Otter signed SB 1254 into law despite overwhelming opposition from the higher education and law enforcement communities
Kansas - in 2013, Governor Brownback signed into law legislation that creates a provision where colleges and universities cannot prohibit concealed carry unless a building has “adequate security measures,” however, governing boards of the institutions may still request an exemption to prohibit concealed weapons for up to 4 years
Mississippi - conceal carry law (2011) declares that colleges and universities can no longer prohibit concealed weapons for those who have completed a voluntary “enhanced” training program for a concealed carry license. According to an Official Memo from the office of Attorney General Jim Hood, those with an “enhanced” concealed carry permit must have the proper documentation with them at all times. Because the law remains unclear, many colleges and universities have banned firearms from dorms, events centers and dining halls.
Oregon - in an Oregon Court of Appeals case (2011), three judges concluded that Oregon public colleges and universities no longer have authority to ban weapons on the physical grounds of a campus. Each school does however, have discretion as to whether to permit concealed handguns inside buildings, dormitories, event centers, and classrooms.
Private colleges and universities may still prohibit weapons throughout the entire campus including grounds.
On March, 2, 2012, the Oregon Higher Education Board voted unanimously to ban weapons in all seven state colleges and universities.
Utah - while the Utah State Board of Regents generally has the power to enact regulations governing the conduct of university and college students, faculty, and employees, Utah law expressly reserves to the Utah State Legislature the authority to regulate firearms at higher education institutions. Therefore, while the Utah State Board of Regents maintains limited authority to regulate firearms in the areas listed below, it may not otherwise authorize higher education institutions to restrict the lawful possession or carrying of firearms. See Utah Code Ann. § 53B-3-103(2)(2002)
Wisconsin - in 2011, Governor Walker signed into a law, sweeping changes to the state’s gun laws. At the time, Wisconsin was one of only two states to prohibit the carrying on concealed firearms. The 2011 Senate Bill 93 changed things in many areas, including allowing concealed weapons on college campuses (public and private). The law contains a provision that allows colleges to post signs prohibiting the carrying of concealed weapons in buildings on campus.
