What level of investigation is necessary for a position that requires only Confidential access?

For a position that requires only Confidential access, a Tier 1 investigation is the appropriate level of investigation necessary. Tier 1 investigations are designed for positions that grant access to information classified at the Confidential level, which involves a basic background check to assess an individual's trustworthiness and reliability.

In this context, Tier 1 investigations include checks such as reviewing criminal history, credit history, and interviews with references. This level of investigation is sufficient for assessing individuals who need access to less sensitive information, ensuring they meet the necessary personnel security standards without requiring the more comprehensive checks associated with higher tiers, such as Tier 2, Tier 3, or Tier 4, which are reserved for positions with greater access to sensitive or classified information.
