Summary:
This report provides a primer on some of the fundamental aspects of the security clearance
process, using a “Frequently Asked Questions” format.
A security clearance is a determination that an individual—whether a direct federal employee or a
private contractor performing work for the government—is eligible for access to classified
national security information. A security clearance alone does not grant an individual access to
classified materials. Rather, a security clearance means that an individual is eligible for access. In
order to gain access to specific classified materials, an individual should also have a demonstrated
“need to know” the information contained in the specific classified materials.
There are three levels of security clearances: Confidential, Secret, and Top Secret, which
correspond to the levels of sensitivity of the information that a cleared individual will be eligible
to access. In addition, there are two major categories of classified information that require
additional handling and access restrictions—Sensitive Compartmented Information (SCI), which
includes intelligence sources, methods, and processes, and Special Access Programs (SAPs),
which are highly sensitive projects and programs. These categories exist for classified
information that has been deemed particularly vulnerable. Eligibility standards and investigative
requirements for access to SCI and SAPs are higher than for access to information otherwise
classified at the same level, which further restricts the number of individuals eligible for access.
Federal employees and private contractors must be cleared in order to gain access to classified
materials. An individual may not obtain or initiate a security clearance on his or her own. A
sponsoring federal agency initiates the process and will make the final security clearance
determination based on a background investigation.
Although the process involves a number of stages, the key steps to obtaining and maintaining a
security clearance are (1) agency sponsorship and submission of clearance application materials;
(2) a background investigation, the extent of which may vary by level of clearance; and (3)
adjudication to determine whether an individual is deemed eligible for access. Adjudication and
final clearance determinations are generally handled by the sponsoring agency. To maintain a
security clearance, an individual is also subject to periodic reinvestigations and, more recently,
continuous monitoring and evaluation of his or her background.
Previously, the Office of Personnel Management, Federal Investigative Services (OPM-FIS)
oversaw approximately 95% of all background investigations. On October 1, 2016, President
Obama transferred responsibility for investigative work and related services from OPM-FIS to the
newly established National Background Investigations Bureau (NBIB). Like OPM-FIS, the NBIB
conducts some of the investigative work itself and contracts the rest out to private firms.
Typically, the costs of a background investigation, including background investigations of private
contractors, are paid for by the requesting agency. While the final determination to grant or deny
a security clearance is typically made by the requesting agency, with certain exceptions a security
clearance granted by one agency must be accepted by other agencies. It is difficult, however, to
determine the degree to which reciprocity occurs between agencies.
