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?
I did. He is a bit uneven with his maturity. As long as he is happy (fed, good sleep, exercise, and mentally stimulated), he can come across as supper mature. He is well behaved and a leader.
But when stressed, mine can whine to world class level but that bit of immaturity is usually saved for home (generally when hunger, tiredness, not enough exercise and boredom are felt at the end of a long day).
After the skip, he did cry with the teacher after school one time when we stopped to talk to her about a writing assignment that he was having problems with...but it didn't work with her and he actually listened to her advice went home and finished the assignment in an hour so that he could go to a birthday party the next day.
I also believe that many kids will rise to the expectations needed at the next level. Really it is only one grade level up...how different is a 5 year old to a 6 year old (especially when like you mention there is a range)? This argument might have merit if you were talking 5 jumping in with 10 year olds.
