Which tier corresponds to non-critical-sensitive positions?

The appropriate tier corresponding to non-critical-sensitive positions is Tier 1. Tier 1 is designed for positions where the risk to national security is relatively low, requiring limited access to sensitive information. It includes roles that do not involve direct access to classified materials or sensitive national security functions. Understanding the tiered structure of personnel security is vital in determining the level of scrutiny that individuals must undergo based on the sensitivity of their roles, which influences the background investigation processes.

In contrast, Tier 2 pertains to moderate-risk positions with more responsibilities and access to sensitive information, while Tier 3 is designated for high-risk roles that require access to classified data. Tier 5 typically corresponds to the most sensitive positions, involving extensive access to national security-related information. Thus, Tier 1 is the correct designation for non-critical-sensitive positions primarily due to its focus on lower-risk responsibilities and limited access.
