Which SEAD addresses the use of the polygraph in personnel security determinations?

• A. SEAD 1
• B. SEAD 3
• C. SEAD 5
• D. SEAD 2

Answer: (D)

The policy about using a polygraph in personnel security determinations is set in a directive that governs how polygraph information can be used in the vetting process. This directive defines when a polygraph may be employed, who is authorized to administer it, how the results are handled, and how they factor into overall adjudication. It also addresses privacy protections and the limitations of the polygraph, making clear that results are one piece of evidence among many and not the sole determinant of a clearance decision. The other SEADs cover different aspects of security policy and do not specifically regulate polygraph use in personnel determinations, so the directive dedicated to polygraph policy is the one that addresses this topic.
