To obtain a security clearance, enabling access to sensitive information, individuals will be subject to a federal background investigation and must meet eligibility requirements, including demonstration of non-use of illegal drugs for 12 consecutive months prior to submission of the clearance request. Non-use of illegal drugs is initially determined through an initial drug screen and review of the individual's Questionnaire for National Security Positions (QNSP). Once the security clearance is granted, individuals will then be subject to random and for-cause drug testing. During the course of the federal background investigation, the other following areas will also be examined: employment and school records, criminal history, financial and credit history, academic performance and attendance, and residence history. If performance in any of these or other areas would preclude eligibility for a security clearance, graduate students interested in the program should not apply.
