What is the primary function of the Joint Verification System (JVS)?

The primary function of the Joint Verification System (JVS) is to verify security clearance eligibility. This system is designed to support the security management processes by ensuring that individuals who require access to classified information meet the necessary security clearance requirements. It plays a crucial role in maintaining the integrity of security clearances across various agencies and ensures that all personnel who have access to sensitive information have been thoroughly vetted and approved based on their eligibility.

While documenting personnel records and auditing clearance processes are essential functions within the broader context of personnel security management, they are not the main focus of the JVS. Similarly, training personnel, although important, falls outside the scope of what JVS specifically aims to accomplish. Thus, the correct answer highlights the JVS's specific role in verifying clearance eligibility, which is vital for national security and information protection.
