What does SSBI stand for in relation to Personnel Security Investigations?

SSBI stands for Single Scope Background Investigation. This term is crucial in personnel security as it refers to a comprehensive investigative process used to assess an individual's suitability for access to classified information or employment in sensitive positions. The SSBI examines various factors, including the individual’s employment history, education, criminal record, and overall character and conduct.

This type of investigation is typically required for individuals seeking a security clearance at higher levels, such as Secret or Top Secret. The "Single Scope" indicates that the investigation covers multiple aspects of a person's life and background, allowing for a holistic view conducive to making informed security determinations. The thoroughness of the SSBI aims to ensure national security by preventing unauthorized access to sensitive information.
