What type of PSI is employed for Continuous Evaluation Programs?

The type of Personnel Security Investigation (PSI) employed for Continuous Evaluation Programs is the Single Scope Background Investigation. This investigation is comprehensive and delves deeply into an individual's background, covering criminal history, financial status, education, employment history, and other relevant factors.

Continuous Evaluation Programs are designed to monitor individuals on an ongoing basis to ensure their continued suitability for access to classified or sensitive information. The Single Scope Background Investigation provides the necessary depth and breadth of information to facilitate this continuous evaluation process, allowing for the identification of any changes in an individual's status that might affect their security clearance.

Other types of investigations mentioned, such as the National Agency Check with Local Agency and Credit Checks or Access National Agency Check with Inquiries, are generally used for initial background checks or specific circumstances, but they do not provide the ongoing, thorough assessment needed for continuous evaluation. The Periodic Review Investigation is typically used for regular re-evaluations of security clearances but does not provide the same level of adaptive oversight as the Single Scope Background Investigation does within a Continuous Evaluation framework.
