Federal activity overview — NACI (National Agency Check with Inquiries)
Security clearance · Confidential level
The NACI is the baseline investigation for federal employees in non-sensitive, low-risk positions. While not a security clearance per se, it is the standard background check for most federal contractor positions that do not require access to classified information or sensitive systems.
NACI-equivalent investigations are required for contractor personnel accessing federal facilities, non-sensitive IT systems, and unclassified government networks. Many civilian agency contracts require at minimum a completed NACI for all on-site contractor personnel. This is the most accessible level for small businesses entering federal contracting.
