Update: the school appears to be concerned about DS's maturity level which they deem to be "age-appropriate in his social, emotional, and attention development."
We agree with this assessment but he is also curious, loves being with older kids, and has good focus when he gets into something. So our feeling that is, in totality, he will be within the normal range of "emotional/social maturity" that you might see in any 1st grade classroom. Perhaps on the lower end, but still within the acceptable range.
Has anyone accelerated a kid of "average maturity"? Any tips for advocacy?
