Types of Investigations:

  • National Agency Check (NAC) – an integral part of all background investigations, consisting of searches of the OPM Security/Suitability Investigations Index (SII), the Defense Clearance and Investigations Index (DCII), the Federal Bureau of Investigation (FBI) Identification Division's name and fingerprint files, and other files or indices when necessary.
  • National Agency Check and Inquiries (NACI) – the basic and minimum investigation required on all new Federal employees consisting of a NAC with written inquiries and searches of records covering specific areas of an individual's background during the past five years (inquiries sent to current and past employers, schools attended, references, and local law enforcement authorities).
  • NACI and Credit (NACIC) – this NACI includes the addition of a credit record search.
  • Access NACI (ANACI) – initial investigation for those who will need access to classified national security information at the "confidential" or "secret" level. The ANACI includes a NACI and credit coverage with additional local law enforcement agency checks.
  • Child Care NACI (CNACI) – an enhanced NACI designed to meet special investigation requirements for those who are in child care provider positions. This investigation includes a search of records of criminal history repositories of the state where the subject resides.
  • NAC with Local Agency Check and Credit (NACLC) – an ANACI without the written inquiries to past employers, schools attended, etc. It is designed as the initial investigation for contractors at the Confidential and Secret national security access levels.
  • Minimum Background Investigation (MBI) – this investigation includes a NACIC, a face-to-face personal interview between the investigator and the subject, and telephone inquiries to selected employers.
  • Limited Background Investigation (LBI) – this investigation includes a NACIC, personal subject interview, and personal interviews by an investigator of subject's background during the most recent three years.
  • Background Investigation (BI) – this is a more in-depth version of the LBI since the personal investigation coverage is the most recent five to seven years. This investigation is required of those going into "high risk" public trust positions.
  • Single Scope Background Investigation (SSBI) – a government-wide investigation required of those who need access to Top Secret classified national security information. This investigation covers the past seven years of the individual's activities. It includes a verification of citizenship and date and place of birth, as well as national records checks on the individual's spouse or cohabitant, interviews with selected references and former spouses.
  • SSBI Periodic Reinvestigation (SSBI-PR) – the required five-year update investigation for those who have Top Secret security clearances. It consists of personal investigative coverage of employments and residences since the previous investigation, including interviews with all former spouses divorced during the coverage period. A search of the U.S. Treasury Department's financial data base is also included.
