Well then, perhaps its about time to pass someone on basis of competency rather than attaching some arbitrary grade at some point in time, that has poor correlation to future skills. Allowing someone to continue trying and learning seems much better method rather than "whoops you had test anxiety or had insomnia and flunked your singular test". And if this is what's needed and is being forced on US's teachers, so be it.
