Which of the following is NOT a function of the TAC?

The correct answer highlights a vital distinction in the functions of a Terminal Agency Coordinator (TAC) within the NCIC framework. In this context, performing criminal background checks is generally a function undertaken by law enforcement agencies or authorized personnel, rather than a responsibility of the TAC.

The TAC serves as a liaison between their agency and the NCIC, overseeing the proper usage and dissemination of NCIC information, ensuring compliance with regulations, and facilitating access. Their functions primarily include maintaining user access, managing training records, and validating data—tasks that directly support the integrity and security of the information systems rather than executing legal checks on individuals.

This understanding is crucial because it emphasizes the specific roles and tasks designated to a TAC, illustrating that while they play a significant role in maintaining the operational standards of the database, they do not directly carry out criminal background checks, which are typically done through specific protocols followed by law enforcement personnel.
