Here is one study that directly addresses academic performance difference in males and females by start time. It finds 16% of the difference in gender grade gap can be attributed.

It’s only one study rather than a broad meta study but it fits with many of the other findings in those other linked papers.

I think having more school entrance periods would be an interesting experiment. Shift Boys entrance by 6 months and have 4 cohorts a year for school start date so everyone in each class is within 3 months of each other. Then you can target curriculum against current development state. Or if you could ever have a reliable test for behavioural development age you could use that as an entrance threshold within certain bounds.

The calendar/redshirt affect is real without considering gender and it’s amplified in young boys starting earlier. It’s also a poverty problem as people who can afford a additional year of child care can afford to redshirt whereas lower income have more difficulty.

What does redshirt mean?
