Which of the following is a criterion for PFA participation eligibility for Active Duty Sailors?

Participation eligibility for the Physical Fitness Assessment (PFA) for Active Duty Sailors requires that they pass all physical tests. This is important because the PFA is designed to assess a Sailor's physical readiness, which is crucial for maintaining operational effectiveness in all Navy missions. A Sailor must demonstrate their physical capability by successfully meeting the standards set forth in the PFA; failure to pass these tests typically disqualifies them from participating in the assessment.

In contrast, other factors like having a valid medical waiver may allow some Sailors to bypass certain physical requirements, but passing the necessary tests is the fundamental criterion for eligibility. Similarly, having two or more PFA failures would negatively impact a Sailor's standing rather than determine their eligibility to participate. Lastly, opting out of the PFA is not permitted, as it is a mandatory component for maintaining readiness in the Navy. Therefore, passing all physical tests is the correct and essential criterion for participation in the PFA.
