I don't think it would go over well with the principal if I reported it. She and I have history... Even calling ahead or CCing her could seem like going over her head. Maybe she is going to report it herself, anyway. I would think she would rather report it and blame the whole thing on the sub than risk anyone finding out that she didn't report it.

I am going to talk to her to find out what she is going to do and what it will mean to my DD if the score is invalid. There may be an alternate assessment. Hey, maybe they could use her recent WISC scores--those show her above the 95%ile.
