Sharon, it seems to me that a GAI of 150 would be fairly rare even among a group of children that tend to score in the 130s, and it fits with the math achievement score of 160. I'm not saying you haven't seen some children with similar scores, but if you have "quite a few" you are in statistically rare territory. As for "the PG range", it seems to be a matter of some vagueness and disagreement. smile
