Rocky, I have two 2e kids - my oldest has dysgraphia and has a very similar dip in processing score (but was assessed with different tests). Even though my ds seemed to be perfectly capable of functioning in a regular classroom environment from his early elementary teacher's perspectives, he was soooo unable to show his knowledge fully when he had assessments given via handwriting, especially if it was a timed exercise. If there's anyway you can get a private eval done through a neuropsych I would - it was extremely helpful to us in understanding what was up with our ds, and it has been essential information to have in advocating for appropriate placement for our ds in school. Without the data and knowledge we gained through the eval, we would have had an extremely difficult struggle convincing any of his teachers that he needed more challenge in school - they only saw him through the lens of his output speed.

Best wishes,
