The Naglieri is a more of a non verbal test so is really geared toward your son's strengths. I would not categorize your daughter as non gifted just because she did not do well on that one test. Our former district uses the Naglieri as a screener test and you only move on if you do well enough on that test. I don't know that I would have trusted that test as a true indicator of where my DS was - he did not have to take it because they had already administered the WJ cognitive prior to a grade skip. We later had DS tested with the WISC for application to a gifted program and his VCI was 20 points higher than his PRI and although both were in the gifted range it was clear that his greatest strength was verbal not perceptual.
