Not a spoiler, but rot13′d for explaining the joke:
“All of you in this room… have received grades of at least Acceptable. Neville Longbottom… who took this test in the Longbottom home… received a grade of Outstanding. But the other student who is not here… has had a Dreadful grade entered on her record… for failing the only important test… that was given her this year. I would have marked her even lower… but that would have been in poor taste.”
Somewhat off-topic, and I obviously had an advantage from already knowing what the joke was, but I managed to decoe your rot13 word-for-word by counting the number of letters in each word and identifying a few matching letters.
I was… irrationally excited when I managed to do so.
