Not only that, but poorly performing students are more likely to be male, whilst excellent students are more likely to be female. This is true across almsot all disaplines.
I'd take this one step further, and claim - from anecdata - that kids should be in quarters, and defer middle school until 6*4 or 7*4 quarters have been reached for girls and boys respectively.
My class in highschool, mostly people who ended up mathematicians, doctors, etc, most of us were born in the first quarter of the year. Do take with a large grain of salt as a) it's been 10 years, and b) this is likely biased bc of the book "outliers".
Functionally doing this with both of my children (though not repeating curriculum) after lots of debating and stress. Adding the expectation into the child's head of being "One of the Smart Ones" seems incredibly powerful moving forward.
