Yogawordmom... we had a similar issue with school. My DS is in K and they had him assessed at reading on a 2nd grade level. This was the highest group. They insisted he was reading at second grade even though at home he's devouring books at a much higher reading level. We had him tested and he's reading at an almost 6th grade level, and comprehension was just as high.
