Security Clearance FAQs


Confidential Security Clearance – This is the lowest level of security clearance. It allows the holder to access information or material that may cause damage to national security if disclosed without authorization. As part of the investigative process, the applicant’s foreign employment, immediate relatives and marriages, and other personal relationships are scrutinized. Confidential security clearances are re-investigated every 15 years, with the clearance either renewed or revoked at that time.

Secret Security Clearance – This security clearance level provides access to information or material that may cause serious damage to national security if disclosed without authorization. It requires a National Agency Check, a Local Agency Check, and a credit investigation. Bankruptcy and unpaid bills, as well as criminal charges, may disqualify an applicant. A poor financial history is the primary reason for rejection, and foreign activities and criminal record are also common causes for disqualification. Secret security clearances are re-investigated every 10 years and are either renewed or revoked at that time.

Top Secret Security – This is the highest level of security clearance. It provides access to information or material that may cause exceptionally grave damage to national security if disclosed without authorization. In addition to generic Top Secret clearance, there is also Sensitive Compartmented Information (SCI) and Special Access Program (SAP) clearance. SCI clearance is required for information that must be contained within a certain group of people, while SAP clearance is needed to work on a particular top secret project, often one that’s so secret that its existence cannot be acknowledged. Top Secret security clearances are re-investigated, and either renewed or revoked, every five years.
