Which statement about the National Agency Check (NAC) is true?

• A. It is never used.
• B. It is conducted as part of all other types of investigations.
• C. It is optional for new federal employees.
• D. It is only used for low-risk positions.

Answer: (B)

The National Agency Check serves as the baseline element in federal background investigations, providing a starting look at an applicant’s history by reviewing records across multiple federal agencies. This foundational check is included in every investigation type, establishing a consistent baseline before any additional inquiries are added for higher-risk roles. It isn’t unused, not optional, and not limited to low-risk positions—different investigations build on this initial NAC rather than omitting it.
