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.



As a preschool teacher, stuff like this is always nice to read. However, there’s also studies that show that kids that go to forest schools do quite well in school, compared to kids who go to more “academic” institutions, so I have my doubts about the importance of structured classrooms.
Generally I think this might support the idea that preschool- and primary education systems work better if you don’t separate the kids based on class or academic ability? I’m pretty sure that’s more normal in the private sector in the US, than in the public preschools? I’m not American, though.
