To become a detective in Tennessee, particularly with the Tennessee Bureau of Investigation (TBI), there are several essential requirements that candidates must meet. First and foremost, a bachelor's degree in criminal justice, forensic science, or a related field is typically required, as this educational background provides the necessary knowledge and skills for investigative work. Additionally, candidates must be at least 21 years old and a U.S. citizen, ensuring that they meet the legal age and citizenship criteria for law enforcement positions. A good moral character is crucial, which is assessed through a thorough criminal background check and fingerprinting. Furthermore, candidates must demonstrate the ability to possess and use firearms, as detectives often need to carry weapons while on duty. Finally, a physical examination is required to ensure that candidates are fit for the demands of the job. Meeting these criteria is the first step toward a rewarding career as a detective in Tennessee.
