My eldest is 9yrs 10mths, tested under ideal conditions by a great tester she came up with a FSIQ of 131 on the SB5 three months ago, with a VS strength 135-136 (sorry I can't remember exactly) and with a WM weakness (80th?), even on the SB5 which has WMI tests that she is much more able to engage with. This is a vast improvement on her WISC two years ago, which had VCI 96th and WMI 13th, and PRI was about 89th I think, despite this being her strength now - I am sure due to visual issues. Shed gifted, she's not HG or PG.
In the last two years we have had OT, swimming, piano, a CAPD diagnosis, ADHD-I diagnosis, tests for this that and the other... I can't get her diagnosed with dyslexia despite her history (took 3 years to fully "get" the alphabet!!), because now she reads at least at grade level and for pleasure... But she fails standardized tests because she can't understand what is required of her...
I feel your pain. And confusion.
Next week she's having a combined speech pathologist / psych assessment for ASD. The more I read the more I suspect that being female and gifted, and perhaps the way we have raised her, has masked being somewhere on the mild end of the spectrum. There is a whole lot about her that I thought was normal (because she's like me or DH) or I thought was her being deliberately obtuse, or cheeky, or had just ignored that I now realize should probably have been ringing alarm bells. Apparently it wasn't supposed to take me months of painstaking instruction to teach her the correct use of pronouns as a toddler, but it never occurred to me to talk to anyone about it because her speech was "advanced" and drawing comments!
Anyway I found "different minds" and "misdiagnosis and dual diagnosis" really useful reading.
