Which of the following is NOT one of the four civilian position sensitivity levels?

The correct response identifies "High-Security" as a term that does not correspond to one of the established civilian position sensitivity levels. In personnel security, there are four recognized sensitivity levels: Non-sensitive, Special-Sensitive, Critical-Sensitive, and High-Sensitivity, which encompasses the well-defined categories based on the potential impact of a position on national security and other critical functions.

Non-sensitive positions are those with minimal or no access to sensitive information, while Special-Sensitive roles involve positions that require a high level of trust due to their access to highly classified information. Critical-Sensitive roles are similar but typically involve even more stringent requirements given the nature and implications of the work involved.

"High-Security," however, is not an official designation used to classify civilian positions, making it the correct answer in this context.
