I had given up on my son's handwriting and pretty much decided typing and voice technology was the way forwards, but OT persuaded us to give HandWriting Without Tears a go. It is an American scheme and it was really successful for us. At age 7, he went right back to basics starting with making letters out of wooden strips, then progressed to writing on a mini blackboard. The school were trained to use it but because of a staff change around, they stopped doing it with him at school. I could have done with continuing support from school to reinforce what I was doing at home and make it really successful. Worth trying though.
