Carol:
That answers part of my question perfectly. Thanks, Annemehr. I'd
forgotten about the OWLs being conducted by outsiders.

But still, Flitwick administering the DADA OWL instead of the Charms
exam? If he's qualified to do that, he's certainly qualified to teach
the subject. So why doesn't Dumbledore just hire him as DADA
instructor once and for all and let someone else teach Charms? If the
 position was open when Snape first applied for it and Flitwick was a
member of the Wizarding Exams Authority, why didn't DD just ask
Flitwick to teach it then? No Quirrell, no "jinx," no jealousy on
Snape's part of the DADA professor. It would have been the perfect
solution. (Unless you count the need for a different DADA instructor
each year as a plot requirement, but that doesn't answer my questions.)
