My DS just received NNAT scores, and I'm very confused. He scored 25 points lower on the NNAT(mid 120's) than his FRI (low 150's) on the WISC. So, what does the NNAT actually measure? I had assumed it would correlate strongly to the WISC FRI, or at least the matrix reasoning subtest, on which he scored > 99.9 percentile. Or are the NNAT problems much more heavily loaded by visual working memory than the corresponding WISC FRI problems? DS was just average in the picture span subtest on WISC, for what it's worth.
Now, I'm worried that my DS will be excluded from gifted pull outs and gifted programming, despite the high 130's FSIQ.
