SECURITY CLEARANCE 101: The lowest level of security clearance needed for civilian contractors

Post Date: August 4, 2021 | Category: Around the World, General Information



A National Agency Check with Inquiries (NACI) is a background investigation primarily for government employees who will not have access to classified information. This investigation is appropriate for positions designated as public trust positions that require responsible and trustworthy employees, but with no national security impact.

The primary reason that the NACI is not an appropriate investigation for a security clearance is that a credit check is not required. When a security clearance adjudicator makes a clearance determination, the decision is based on the whole person concept as related to 13 adjudication criteria. These criteria are designed to help assess whether or not a person has demonstrated trustworthiness to protect classified information. Trustworthiness depends on a person’s allegiance to the United States, character and health issues. For example, what a person spends money on, timeliness of payments, relationships, and etc. are identified in credit reports. The credit check goes a long way in addressing all three issues. Therefore the NACI is not thorough enough to make a security clearance determination.

An example of a position that requires a NACI is for those performing information technology roles. These professionals are privy to sensitive but unclassified government and contractor information that reside on computer systems and networks. This information includes technical data, personnel records, contract data, programmatic details and etc. Because of the sensitivity, a background investigation is required.

The NACI is good for 5 years and the elements include a completed National Agency Check where federal agency databases are queried and a law enforcement check. Written correspondence is required to verify education, employment, and character references.
