She is 9 going into 5th grade, so she is young for her grade and I had concerns about the fact that she's actually behind the kids in the next lower grade (despite having access to a higher level curriculum than them). With a 6 year old it's possible that you will see a lot of changes in the next year or two.

DD did really well on both visual-motor integration tests that she did (I think over 80th percentile). If she had done poorly on those, the diagnosis would probably have been "dysgraphia". I think technically she should still be able to qualify for school services as LD though, because of the large gap between cognitive ability and her writing achievement test score, and other information processing concerns, like slow processing speed.

I personally see dysgraphia as kind of a spectrum, similar to other disorders. Some people are very mild and others are very severe.
