I'm pretty sure that the test can be rescored against 6th grade norms if that's what they're wanting to see.
We were told that DD9 needed to get 75% or above on at least 2 sections to even be considered for a grade skip. She was supposed to be given the 6th grade test. The school psych. just emailed to say they gave her the 7th grade version because all kids in this county get a 1 year above level test. What makes no sense (to me anyway) is to compare her to other 9 year olds (and the psych. said the comparison is to usually same age kids, not grade) when she already tests 99% against that age. I just fired off another email to the school psych. to see just exactly what age DD was normed against (if I am using the correct terminology).
