Who must sign the validation certification letter before it is returned to the TCIC control center?

The validation certification letter must be signed by the chief, sheriff, TAC (Texas Agency Coordinator), or records supervisor because these individuals hold significant authority and responsibility within their respective law enforcement or agency structure. Their signature signifies that the submission complies with the necessary validation processes set forth by the Texas Crime Information Center (TCIC).

This requirement ensures that the validation process is overseen by someone with the requisite authority, providing an additional level of verification and accountability. These roles are typically involved in overseeing the procedures and ensuring that the data being submitted for validation is accurate and complies with TCIC's standards, ultimately ensuring the integrity of the information maintained by the TCIC control center.
