On the UMD, which SAR code indicates the need for a security clearance level with a Single Scope Background Investigation (SSBI)?

The SAR Code that indicates the need for a security clearance level with a Single Scope Background Investigation (SSBI) is associated with the Top Secret designation. A Top Secret clearance is required for access to information that could cause exceptionally grave damage to national security if disclosed. The SSBI process is a comprehensive background check designed to evaluate an individual's loyalty, character, and trustworthiness, which is critical for positions requiring access to highly sensitive and potentially damaging information.

In the context of the other codes, while the Confidential and Secret levels do require background checks, they do not necessitate the same level of scrutiny as the SSBI. Sensitive Compartmented Information falls under highly classified material that may require additional clearances based on access to specific compartments but is not directly associated with the SSBI qualification. Therefore, the correct correlation to the SSBI requirement is the Top Secret level, as it directly connects to the highest degree of investigation needed for national security roles.
