Tennessee state law requires anyone acting as a private investigator to hold a license issued by the Tennessee Department of Commerce and Insurance. Minimum licensing requirements for private investigator applicants state that all applicants must be able to pass an in-depth background check, including fingerprinting, complete all training and continuing education programs, and have sound moral and ethical character. Many Knoxville and Southaven private investigators worked in an investigative capacity prior to obtaining their PI license, often through police or military backgrounds.
