What tier is described as "non-sensitive, low risk" in FIS classification?

Tier 1 is classified as "non-sensitive, low risk" in the Federal Investigative Standards (FIS) classification system. This tier is associated with positions that do not require access to classified information or pose a significant threat to national security. Personnel in Tier 1 roles are subjected to more minimal vetting compared to higher tiers, reflecting the lower level of risk involved in these positions.

Understanding the tier system is crucial for identifying how different levels of risk are managed in personnel security. Higher tiers typically require more extensive background checks and continuous monitoring due to the sensitive nature of the information or responsibilities involved, whereas Tier 1 focuses on roles that, while still subject to some level of oversight, do not engage with sensitive information that could impact national security or public safety.
