Yes different norms, eY1 the first time and eX2 the second time. Quick note that if your child tests within 3 points of making the minimum there may be a little bit of wiggle room. At least that is what they told me on the phone. I e-mailed them to see if they would make an exception for a grade skip score (Yes I want it both ways)for a 2nd/3rd grade summer writing course.
