Guiding principle adjudicators follow when evaluating eligibility for access to classified information?

• A. Any doubt about an individual's eligibility must be resolved in favor of national security.
• B. Any doubt should be resolved against national security.
• C. Any doubt about an individual's eligibility must be resolved in favor of the applicant.
• D. Doubt should be ignored.

Answer: (C)

The guiding principle is to apply the benefit of the doubt in favor of the applicant when there is doubt about eligibility. In adjudicating access to classified information, decisions should not hinge on ambiguous or inconclusive evidence; instead, uncertainties should be resolved in a way that supports granting access unless there is a clear, credible basis to deny. This approach aligns with a careful, fair evaluation that weighs the whole person’s history and mitigating factors, while still safeguarding national security by ensuring risks are not ignored. If the evidence is genuinely inconclusive, the prudent outcome is to favor granting access rather than deny it.

Denying access or ignoring doubt would tilt the process unfairly or unnecessarily against the applicant, and always prioritizing national security in the face of any doubt could lead to incorrect disqualifications.
