Just came across this on his report,
I'm not sure if this part, "Because ****, who was just turning 4, was beyond the norms for Kindergarten, the scores above compare him to beginning 1st graders." means that he was scored as a first grader, or if his scores are at a first grade level.
He was scored as if he was a beginning first grader, but his scores reflect that he *performed* more like a child beginning second grade (for the lowest reading scores, 2.1) or third grade (for the highest one, 3.1). So, at age four, he is performing three to four years ahead of age peers.
I don't really think there is any doubt that he is "severely" gifted.
