Who is a uniquely certified professional trained to assess loyalty, trustworthiness, and reliability and determine eligibility for access to classified information?

• A. Adjudicator
• B. Adversary
• C. Administrative Inquiry
• D. Access

Answer: (A)

An adjudicator is the trained professional who evaluates a background investigation and applies the applicable security-adjudication guidelines to decide if someone is eligible for access to classified information. This role specifically focuses on loyalty, trustworthiness, and reliability, and has the authority to grant, deny, or condition access based on the overall risk assessment. The other terms don’t fit: an adversary is someone who seeks to exploit security, not the evaluator; an administrative inquiry is a type of investigation activity, not the decision-maker; and access is the permission itself, not the person making the determination.
