I took a quick look back at your original post about your dd - you'd mentioned there that the psych who assessed her recommended sending her to a school for gifted children, and she was testing to get into a public gifted school. Did she get in? If she did, send her! She doesn't have the scores required to get into DYS, but that doesn't mean she's not gifted and it doesn't mean she won't thrive with accelerated work/pace at school. That's my first piece of advice.
My other bit of advice, fwiw, is to try to figure out what's up with the low coding score. Did you the psych have any thoughts behind it? Did he feel it was a valid score? There are quite a few of us here who have kids with large discrepancies in processing speed subtests vs the other WISC tests, and sometimes that discrepancy is an indication that a challenge exists that your child can benefit from either accommodations or therapy etc. Dysgraphia is one of the possible reasons, but there are others too. FWIW my ds with developmental coordination disorder and dysgraphia has a very large discrepancy in coding vs his other subtests, and he absolutely needs accommodations in school *but* he thrives in accelerated classes and is bored to tears in grade-level regular paced classrooms. He's doing really well in school with access to his accommodations (laptop, extra time on tests, etc). The two things that are his largest challenges are organization (which is improving with maturity and a heck of a lot of work) and it takes him longer to complete his homework than it takes kids who don't have the low processing speed bottleneck. It's really important to recognize though that the bottleneck and slow speed are in the *output* not in thinking/reasoning ability - and that's what you need to take into consideration in putting together a plan for school subject level.
Back to your original question, yes, your dd is gifted. But I find it helps to not focus on the term as much as it helps to look at your whole child, how she's functioning in school, is she having challenges, figure out why they exist and then figure out how to either work through or around them etc.
