Yes, I agree with alot of what has been said up above. I would drop the "trying" thing because she probably is trying, but with a 2e kid, simply trying isn't necessarily going to get it done. And you don't want to her start thinking, "I'm already trying as hard as I can and it's not good enough, so why bother?"
I think I would also formally request (in writing) an evaluation. Having a great teacher is a great start, but even a great teacher isn't going to cure her of an actual disability. It sounds like her difficulty is not just in handwriting, if she's also having trouble with using organizers, reading graphic novels, and all that. I don't see how any of that will be solved by formal handwriting instruction or just having a great teacher.
Also, have she had a vision evaluation? Like by a pediatric optometrist? I would consider that, if you haven't tried it already.
