GAI at 135 is absolutely gifted - it is 2.3SD above the mean. Remember, DYS cutoff scores are for the profoundly gifted. Most gifted kids aren't that "severely" gifted. This doesn't mean that they aren't truly gifted or that they don't need special programming.
Low processing speed can be a flag for a number of different issues, including problems with attention, visual scanning, and fine motor control. Determining which of these, if any, might be a problem for a given person requires looking at more than IQ numbers, although subtest scores can sometimes be useful in givng an idea of where to start.
Did they use any other evaluation instruments that may have included fluency measures (especially written fluency) or measures of motor or visual-motor skills?
