I personally have never achieved handwriting skills at a grade 2 level. The school forced me to work at it until grade 6, when they finally gave up. Did not affect my academic work in any other area.
Although I think it is good to attempt to work on a given person's weakness, some weaknesses may never be overcome. I feel it is good to work on it until signs of no further progress is seen. At this point, leave it alone for a while and try again. Sometimes it is a matter of waiting until the time is right. Other times, it may be a specific disability and nothing can be done. Just don't assume a weakness in one academic skill is any indication of weakness in others. Allow the child to continue to build on the strengths they show.
Everyone including the most gifted have weaknesses. Some weaknesses are just not as obvious or as much of a concern to society.
