I know people who will adamantly insist that keeping classes within similar development ranges is harmful and will vociferously reject any such proposal, up to and including things such as "gifted" schools and the like.

It's why some schools in (iirc) California did away with higher maths like calculus entirely.

Sadly, it seems there's nothing actually common about common wisdom.

I will admit that I never heard a serious argument from anyone that did not rely on issues not related to individual student's education. If you have any materials on those, I would love to read some of it.

		Montessori advocates for mixed age classes where more advanced help teach the less advanced, as the teaching itself solidifies it in the more advanced student's mind. Not sure if it is valid. But it is something with studies and meta studies that may have been done well or poorly, not just an aesthetic choice. I think Vulcan style training pods driven by AI like khanmigo will end up being better education than the vast majority of students will ever have access to in person. Or consider it the realization of "a young lady's primer" from diamond age.
