What is the focus of Tier 3 Reinvestigation?

The focus of Tier 3 Reinvestigation primarily involves the periodic verification of an individual's eligibility for access to classified information, such as Confidential, Secret, or Department of Energy "L" level access. This process is crucial for maintaining national security and ensuring that individuals with access to sensitive information continue to meet the required standards of reliability, trustworthiness, and loyalty.

This tier of reinvestigation operates on the principle that security clearance holders must be routinely assessed to identify any potential risks or changes in their circumstances that could affect their eligibility. It emphasizes the importance of ongoing evaluations to ensure that personnel remain fit to handle sensitive information, thus safeguarding national security interests.

The other options do not align with the specific intent of Tier 3 Reinvestigation. New job applicant screenings pertain to initial clearances rather than ongoing evaluations. Assessing workplace skills and evaluating employee job satisfaction are generally related to performance and employee engagement rather than security clearance issues.
