Sounds like he'll enjoy the accomodations at least. Hopefully they will give him what you are both hoping for. We are just about to sit down with our school to see what sort of more formal accomodations they can make for DS for our kindergarten year. He is not ready for a grade skip either socially or from a fine motor/writing perspective (they are VERY heavy on writing at our school), but he is FAR ahead in math. I might try to go the EPGY route at school and let him work self-paced (he is really at least at 2nd grade, and in some areas ready for 3rd grade work).

As for "What does the word 'mean' mean?", it's too bad he didn't just stumble onto the idea of "not nice"... :-)
