This sounds a little like my DD6. She is in first grade and has a diagnosis of dysgraphia. She also reads very fast with near perfect comprehension. Almost all of what she reads is above grade level. I don't have any great advice for you because we are still in the thick of things, but I would recommend having her assessed for dysgraphia because sometimes OT can help. Additionally, she may benefit from certain accommodations at school. For example, my DD is allowed "shortcuts" on some worksheets when the aim is to determine understanding rather than handwriting. Additionally, she self-advocated in spelling, and because they know about her diagnosis, her teacher agreed to allow her to do half her spelling test orally. This seems like a little thing but it goes a long way in 1)giving the child confidence and helping them feel understood and appreciated at school and 2)letting her hand rest. Good luck!
