I guess if I get two copies in the mail, then it will be obvious that a copy was not sent to the school.

I wouldn't necessarily assume so. We did NUMATS, not CMITES, but we received two copies in the mail. However, when I was chatting with the person at NUMATS this morning, she actually pulled up my son's scores and mentioned that the school would be sent a copy. I was surprised - we didn't sign up through the school and I don't even remember putting any number in, but it was there in the toolbox (at the bottom of his scores). They are pretty friendly and chatty at NUMATS - I mentioned that we had no "coordinator" and I didn't think anyone else had taken the test from our school, but she looked it up and confirmed that the principal would be the recipient and he could access everything in my son's toolbox. It's weird - I assume that I MUST have given them that information (how else would they have it) but I'm honestly surprised. With my older kids' SAT/ACT scores, we never sent automatically, in case a test went poorly.
