How often are individuals with security clearances generally required to undergo reinvestigation?

Individuals with security clearances are generally required to undergo reinvestigation every five years. This timeframe is established to ensure that any potential issues that might affect an individual's trustworthiness or reliability—such as changes in personal circumstances, financial difficulties, or legal issues—are reviewed regularly.

The five-year cycle allows for an appropriate balance between maintaining national security and acknowledging the stability and reliability of personnel who have proven their trustworthiness over time. This periodic reinvestigation helps organizations keep updated records on individuals' suitability for access to classified information, ensuring continued confidence in their security clearance status.
