I'm a little puzzled as to why anyone would recommend the Naglieri, a purely visual, non-verbal test, to assess someone with visual deficits and auditory strengths for giftedness. Is it simply that the Naglieri is the usual test that that tester administers or that the school district uses? Or is it that the WISC-IV and the SB-V both have high visual-motor demands on some subtests, and the Naglieri doesn't require as much visual motor coordination? You might ask your tester about the RIAS, if the lack of visual-motor demands is the reason for choosing the Naglieri. It has verbal items as well as non-verbal, the visual items are clearer and less visually cluttered than the WISC-IV, and there are no or motor output requirements. It worked reasonably well for my highly verbal son who has problems with visual processing, including visual attention, and with visual-motor integration.
