Who are required to undergo Tier 5 Reinvestigation?

The requirement for Tier 5 Reinvestigation is specifically aimed at military, civilian, and contractor personnel who are in specific sensitive positions. This tier is part of the background investigation process designed to assess an individual's trustworthiness and reliability in roles that require a high level of security access. It involves a thorough examination of various factors, including personal history, financial stability, and character, to ensure that those in sensitive positions are suitable for maintaining security standards.

The rationale for needing this level of investigation is aligned with the critical nature of the roles involved. Personnel in sensitive positions have access to significant information, assets, or systems that could impact national security or the safety of individuals. Therefore, the comprehensive nature of Tier 5 Reinvestigation is warranted to continuously ensure that personnel remain qualified for their roles throughout their service or employment.

In contrast, the other groups mentioned, such as federal employees only, contractor personnel only, or interns and temporary workers do not encompass the full scope of individuals representing the federal workforce in sensitive roles. The requirement encompasses a broader spectrum of personnel that includes both military and civilian populations, as well as contractors, thereby reflecting the multifaceted approach necessary for maintaining personnel security across different sectors.
