Oh, that is frustrating! I have mixed feeling about the test - it's not worthless, but it isn't perfect either and it often makes such a big difference in educational opportunities for kids. Will she get to join the gifted math class now?
My son's quantitative scores have been the most consistent 86th (first grade) to 96th (second) to 98th (third). His verbal and non-verbal score both made huge jumps between 2nd and 3rd grade. The verbal doesn't surprise me as much because of the change from pictures to words - he never was very good at interpreting the picture based problems that he had on his language arts problems in second grade. I don't have any explanation for the non verbal jump though, that's the section I would have expected to stay the most similar.
