Which element of the Personnel Security Program involves evaluating the information contained in reports of personnel security investigations (PSIs) and other source documents?

The element of the Personnel Security Program that involves evaluating information from reports of personnel security investigations (PSIs) and other source documents is known as "adjudication."

Adjudicators consider various factors, including conduct, behavior, and potential risks, to make informed decisions regarding security clearance.
