If an applicant for employment has undergone a nationwide criminal records check pursuant to § 16-48.1-4 within eighteen (18) months of an application for employment, then an employer may request from the bureau of criminal identification of the state police or the local police department a letter indicating if any disqualifying information was discovered. The bureau of criminal identification will respond by stating if an item of disqualifying information was discovered without disclosing the nature of the disqualifying information. The letter may be maintained on file to satisfy the requirements of § 16-48.1-4.
