clearance : Eligibility for access to classified information, commonly known as a security clearance, is granted only to those for whom an appropriate personnel security background investigation has been completed. It must be determined that the individual’s personal and professional history indicates loyalty to the United States, strength of character, trustworthiness, honesty, reliability, discretion, and sound judgment, as well as freedom from conflicting allegiances and potential for coercion, and a willingness and ability to abide by regulations governing the use, handling, and protection of classified information. A determination of eligibility for access to such information is a discretionary security decision based on judgments by appropriately trained adjudicative personnel. Eligibility will be granted only where facts and circumstances indicate access to classified information is clearly consistent with the national security interests of the United States. Access to classified information will be terminated when an individual no longer has need for access. (†1860)
