A 20-year study of 400,000 students found that children who attended public school pre-K earned better grades and test scores through high school than those in other childcare settings. Better-trained teachers and earlier exposure to structured classrooms may help explain why the advantage lasted so long.



But are better grades and test scores just representations of being better at pleasing the grader and taking tests?
My own half-assed ‘study’ of watching my fellow kids and some generations after proved (to me) that having better grades and test scores doesn’t mean having a better life after.
That’s what’s fundamentally wrong with us as a appreciate. 20 years and highly specialized, focused question… “But my different question has an anecdotal different answer!”.
The key issue is: these studies look at correlation but you’re arguing from causation. Don’t do that, please.
To be clear: I don’t know where you’re from and have no idea of the education system you’re referencing to - yet the chances are high that I works agree with you in a different setting.
A correlation study about the influence of early exposure to Kong term evaluation in the same system isn’t it though.
