Thank you all.
I love Polar Bear's post. I need to adjust my definition of a label

Notnafnaf, I'm not worried that it will be lower due to 2e, although certainly that is a possibility too. My DS is a perfectionist and will often refuse to try novel tasks until he has practiced them (mastered them) in private. I've warned the psych about this so she is aware. She seems wonderful so if they click, I'm sure he will be fine at least in the am. He tends to crash after lunch- he just needs to hole up in his room with a book to refuel or he's a bit if a disaster. So I'm concerned he will bomb the achievement testing in the afternoon. Again, I've warned the psych but what can you do? It's a long day for a 6yo, let alone an intense, moody little person

I can't wait until testing is over! I can tell this will be quite a journey and I'm thankful to have this forum. I've learned a great deal reading through posts.
