The Roanoke County Police Department was the first law enforcement agency in southwest Virginia to become nationally accredited through the Commission on Accreditation for Law Enforcement Agencies, Inc. (CALEA). The Roanoke County Police Department was first accredited in 1992, then reaccredited in 1997, 2000, 2003, and 2006. The Department will be up for reaccredidation in August of 2012.
Professionalism in law enforcement has developed over the years. Several organizations have fostered this movement: the International Association of Chiefs of Police (IACP), the National Organization of Black Law Enforcement Executives (NOBLE), the National Sheriff's Association (NSA) and the Police Executive Research Forum (PERF). In 1979, these four organizations created CALEA to develop a set of law enforcement standards and to establish and administer an accreditation process.
