How is the relationship between the three investigative tiers structured?

• A. They are independent.
• B. They overlap completely.
• C. Each investigative tier builds upon the tier below it, with complexity and coverage increasing to match the increased risk at each level.
• D. They are identical in scope.

Answer: (C)

The three investigative tiers are designed as a progressive, risk-based ladder. Each higher tier adds more depth and breadth to the review, and its scope is built on what was already examined in the lower tier. The lowest level establishes a baseline of basic reliability and suitability, while the next tier expands the checks with additional data sources, longer look-back periods, and more thorough verification. The highest tier then layers in the most comprehensive scrutiny, including deeper interviews, broader sources, and greater scrutiny of factors like financial history, foreign contacts, and security risks, to match the increased level of access and responsibility. This approach is about proportionality and continuity: higher-risk roles require more thorough vetting, but that thoroughness builds on the findings from the prior tiers rather than starting from scratch. The tiers are not independent, nor identical in scope, nor do they overlap completely; they are intended to be cumulative and progressively more demanding. For example, Tier 1 might cover basic identity and background checks, Tier 2 adds employment and financial verifications, and Tier 3 includes full-scope investigations with extensive interviews and additional risk assessments.
