My son's scores were much like your daughters's - tested at end of 6th grade, VCI of 162 but PSI of 91. We are considering requesting an evaluation from the school to see if there is an issue that we should be addressing, and as I find out anything else I'll post on here too because there seem to be a lot of us dealing with the same issue!
Unlike your daughter, for my son handwriting does seem to be his issue - he doesn't have good handwriting, won't do cursive writing, and just doesn't enjoy it. When he can type it is much, much easier for him. Heading into the upper grades typing becomes more and more the norm, so hopefully we are heading into school years where he will have better success.
So I don't have anything to offer yet, but wanted to say hello and encourage you to post whatever you find out too!
