Yes, I bet it is the scatter that led to the LD diagnosis.
I haven't gone back to read the beginning of this thread, and I probably confuse everyone on this board, but Cathy, have you already had her evaluated for vision issues (as in, by a behavioral optometrist)? Besides the more obvious clue of dysgraphia, the reason that vision comes to mind is that her scores on the perceptual reasoning are so different from the scores on verbal comp (but then, I wasn't aware until Dottie mentioned it that this might not be unusual among gifted kids?) My dd's scores on the WISC likewise had a lot of scatter, and even though her perceptual reasoning and verbal comp scores were much closer together than that (I think my dd's overall perceptual reasoning score was higher than the overall verbal), the tester had expected her to do better on the block design portion than she did (she kept skewing the designs or something), which they said suggested a vision issue (sure enough, dd has an eye tracking problem and is in vision therapy now - 5 weeks to go, sigh). After all you've been through, a vision eval by the right kind of optometrist should be easy

My dd also has similarly lower scores for working memory and processing speed, and is a definite visual-spatial learner. I have found a number of tips on the website to be quite helpful. You probably already have this, but from the website, here is a checklist for diagnosing dysgraphia
http://www.visualspatial.org/Articles/chklist.pdf and another article about handwriting
http://www.visualspatial.org/Articles/poorhand.pdfAnother article recommends calculating the GAI "if the 4 composite scores vary by 23 or more points, and if the Verbal Comprehension Index and the Perceptual Reasoning Index vary by less than 23 points."
http://www.gifteddevelopment.com/About_GDC/whoaregiftd.htm However, I don't quite understand the second part, about varying less than 23 pts between verbal comp and perceptual reasoning.
Now that I have spewed out a bunch of random thoughts that are probably helpful to no one, I better clean up the house while I can.....
