Given that your DD10 didn't want to take the test, her results may show that she wasn't that into it...
My understanding is that it is normally taken by 8th graders at the start of the school year, so it would be two years above grade level (roughly) for a 6th grader.
Right. This is where the grade skip plays a part. I am looking at my daughter's results as if she were still a young 5th grader whereas she is actually a 6th grader. But! She has been exposed now to 6th grade classes so she takes the test as a 6th grader. Sometimes I wish the elementary school could have accommodated her. Ugh. If I think about it I will get mad about her time in 4th grade when the teacher refused to give her challenging work. Grrrrrr. [/quote]
I understand. DS9 is in 4th but accelerated for math and reading/English (6th). So there's the way of thinking of his scores as those of a 9 year old, but truly, he's a 6th grader for most of what the class covers. In your case, I would think of how much time she has or hasn't had in 6th and balance your viewpoint accordingly. I'm not sure that it matters for the test what happened in 4th (although I certainly understand the frustration in general!).
My guess is she had an off day when it came to the test or that it covered some things she's not as comfortable with yet, while your ODD had a better test day. Or perhaps your ODD's results show that her earlier assessments underrepresented her ability!
