In the late 80’s, only two computer specialists were employed by the TBI. Today, the Information Systems Division (ISD) encompasses more then 100 people, responsible for integrating modern technology with traditional policing. The ISD encompasses a wide variety of complex systems that serve the TBI, local, state and federal criminal justice agencies and the public. From housing the state repository of criminal history records to supporting criminal justice information traffic to conducting background checks for gun purchasers, the ISD staff are committed to providing the most professional, up-to-date services available.
The (ISD is divided into three sections. Identification Services is made up of the Criminal Records Unit (CRU), Applicant Processing Unit (APU), and the Records Processing Unit (RPU). Computer Services is made up of the TN Instant Check System Unit (TICS), the Crime Statistics Unit (CSU), the Tennessee Open Records Information Services Unit (TORIS), and the Technical Systems Support Unit (TSSU). Law Enforcement Support Services is made up of the Law Enforcement Support Unit (LESU), the Fingerprint Training Unit (FTU) and the Tennessee Information Enforcement System (TIES) Operations staff. The ISD also provides technical support, systems analysis, project management, application development of small systems, hardware and software procurement, and information technology planning for all TBI Divisions.
Within the Bureau, the ISD is responsible for delivery of services that augment the Forensic Services Division, the Criminal Investigation Division, the Drug Investigation Division and the Administrative Services Division. In addition, ISD provides services to local, state, and federal agencies through the National Crime Information Center (NCIC), the International Justice and Public Safety Information Sharing Network (NLETS), the Automated Fingerprint Identification System (AFIS) network, the Tennessee Information Enforcement System (TIES) network and the Tennessee Incident Based Reporting System (TIBRS).
