Personnel Security Investigation (PSI)

A Personnel Security Investigation (PSI) is a background check conducted by organizations, especially in government or security-sensitive roles, to assess an individual's trustworthiness and reliability. It examines factors like criminal history, employment record, credit history, and personal references to determine if the person suits a position involving access to sensitive information or areas. The goal is to ensure that only suitable and dependable individuals are entrusted with classified or sensitive responsibilities, thereby helping to protect national security or organizational integrity.
