There are also references to the "research" about how younger children can be harmed by trying to keep up with older ones. Hmm. I've not come across that research yet.
Here is some from the UK:

Children born in August are more likely to under perform in school compared to the children born in September. How does birth month affect academic results and well-being?
The birth month of young children can affect their well-being as well as test scores, according to research published today by the Institute of Fiscal Studies (IFS).
A report out today suggests that children born in August are more likely to have lower confidence in academic ability and to report being unhappy at school. The results also show that children born in the last month of the academic year are also less likely to attend top universities.
I have seen research saying that gaps close in post-elementary grades in the U.S., but the point is that educators can point to research showing that the younger children in a class are more likely to struggle in the early grades. And this makes sense, because older children are smarter, have more endurance, and have more self-control on average than younger ones. What is true for children in general is probably not true for high-IQ school starting school early, however.
