If an individual's position is highly sensitive, which tier would most likely be required?

• A. High Tier (HT).
• B. Low Tier (LT).
• C. Moderate Tier (MT).
• D. All three tiers.

Answer: (A)

When a job function is highly sensitive, the level of background investigation is stepped up to mitigate greater risk. The most thorough vetting, the High Tier, is used to ensure a comprehensive check of criminal, financial, and personal history, as well as potential foreign influence or other factors that could affect trust and reliability in handling sensitive information or critical duties. This deeper scrutiny helps prevent risks before access is granted and supports ongoing monitoring as needed. Lower levels of vetting would not provide enough assurance for highly sensitive roles, and using a moderate tier would leave gaps. The idea is to assign a single, highest appropriate tier for the position rather than applying multiple tiers.
