Which of the following is a service provided by the TCIC?

The Texas Crime Information Center (TCIC) is primarily focused on providing access to criminal history information at both local and state levels. This service is crucial for various law enforcement, judicial, and administrative entities as it enables them to obtain vital information on individuals' criminal backgrounds. Access to local and state criminal history helps in making informed decisions related to law enforcement actions, probation, parole considerations, and other legal matters.

The other options do not accurately represent the TCIC's functions. For instance, tracking international crime statistics is typically within the purview of federal agencies or international organizations rather than a state-level system like the TCIC. Conducting background checks on all citizens is too broad and not a service provided by TCIC; rather, background checks would be conducted on individuals in specific contexts, such as by employers or law enforcement agencies concerning certain cases. Administering vehicle registration and titles falls under the Department of Motor Vehicles (DMV) or similar agencies, not the TCIC. Therefore, the correct answer highlights a core aspect of the services offered by the TCIC.
