I think there might be a pattern across education with a strong ideology (Montessori, Waldorf, Classical education, etc) that they aren't very good at recognizing when the ideology is failing a kid. The relatively weak and mushy educational philosophy of a normal public school is also a somewhat reasonable way to run a school that has to take kids wherever they are at and wherever they came from.
>that they aren't very good at recognizing when the ideology is failing a kid.
I would amend this somewhat to say that most ideologies have aspects that are much less effective in practice than they are in theory. I think this matches your sentiment, but addresses the likely rebuttal of "But X method has this specific element designed to address the shortcoming."
