How often must a Top Secret clearance holder undergo a reinvestigation?

Top Secret clearance holders are required to undergo a reinvestigation every five years. This time frame is established to ensure that the individual's eligibility for access to classified information remains valid. Regular reinvestigations help maintain national security by assessing any changes in an individual's background, behavior, or personal circumstances that may affect their reliability and trustworthiness.

The five-year period allows for a comprehensive review of various aspects of a clearance holder's life, including financial, legal, and personal history, which are essential components in determining their suitability to continue accessing sensitive information. Regular updates through reinvestigation also reflect the evolving nature of security threats and the need for continuous evaluation of those in positions of trust.
