Update: after a long talk with the principal over the phone on Thursday morning he said "I think I will go get him and put in a second grade class today". Guess what? Two days in second grade and he was perfectly fine. I talked to the teacher and she told me he did a meth sheet with the class and was the only one to get 100%. She went ahead and gave him the spelling test, 15 words review from the past six weeks, she thinks he missed two words (words like crocodile).

So, I called a private tester and she will do IQ and achievement testing. Then either help get him moved up to third grade next year or get him an individualized plan if he's in second grade next year.
