Which board is responsible for reviewing appeals of unfavorable DoD CAF determinations?

The Personnel Security Appeals Board (PSAB) is the correct answer because it is specifically designated to handle appeals regarding unfavorable determinations made by the Department of Defense Consolidated Adjudications Facility (DoD CAF) concerning personnel security clearances. The PSAB provides a formal review process for individuals who wish to contest a decision that affects their eligibility for security clearance, ensuring that due process is upheld.

This board's primary responsibility is to ensure that decisions regarding personnel security are made fairly and in accordance with established guidelines, interpreting these principles within the context of the individual’s circumstances. It plays a crucial role in maintaining both the integrity of security clearance processes and the rights of personnel within the Department of Defense.

Other options may mention boards or committees that provide various forms of oversight or review, but it is the PSAB that specifically focuses on appeals connected to security clearance determinations made by the DoD CAF, making it the most appropriate choice in this scenario.
