While you're waiting for the evaluation (which really isn't that far away... even though I know it feels like it's going to take forever waiting) there are things you can do now that might be helpful going into the eval.
1) Make a list of everything you've observed (home and school) that might be relevant - what you've posted above re starting a word then moving on before finishing it - sounds potentially relevant and you'll want to mention it to your ds' evaluator.
2) You can ask your ds to write the alphabet out, upper and lower case letters, in order, and time him while he does this. The task will give you two bits of info: how quickly he writes vs same-age or same-grade peers (to get this #, time him as he writes, calculate # of letters per minute when he's completed the task, and second point of info - you can look to see if he's forming his letters properly - does he start letters from top and move to the bottom, does he reverse any letters etc - all signs that *might* point to dysgraphia.
3) Try to compare his writing with handwriting vs what he can output if you scribe for him. He's still a little young for this to be a really useful test, but it's worth at least trying to see if you notice any significant differences.
Hope some of that helps!
