National Agency Check with Law and Credit (NACLC)

The National Agency Check with Law and Credit (NACLC) is a type of background check required in the U.S. for granting security clearance. The NACLC is used as the initial investigation for contractors at the Confidential, Secret, and L access levels. It is also used as the reinvestigation method for both contractors and Federal employees at the same access levels.

This type of investigation includes:

• Basic National Agency Checks (Security/Suitability Investigations Index, Defense Clearance and Investigations Index, fingerprint classification, and a search of the Federal Bureau of Investigation’s investigative index).

• Credit search covering all residence, employment, and education locations during the last seven years.

• Law Checks covering all locations of residence, employment, and education during the last five years and to all locations of admitted arrest. If 35-day service is requested, all law checks will be scheduled by Record Search. If 75-day service is requested, law checks will be scheduled by a combination of inquiry and record coverage.
