Acceleration is such an individual thing. DD's school does not have a set standard (two years etc). School is as much about learning to get along with different types of people as it is learning. Honestly, if you are accelerated more than two years I imagine the social stuff will be really hard. DD is in 2nd grade and has a 6 year old in her class. She does fine academically but socially the other girls forget that she is there. I wonder if it would not be better for her self-esteem to be the best student in first grade?? If she decides to play sports she will have a difficult time being competitive (only because she is a year or two younger than the other kids). Watching this little girl has honestly changed my mind about acceleration for DD (who scores at the 99.9th percentile across the board) because school life is about so much more than academics. We do lots of after schooling though;).
