I talked to Kelsey about some of the research for her article, and independently came to the same conclusion: despite the earlier studies of achievement being accurate, preschools (including the much-maligned Head Start) do seem to help children in subtler ways that only show up years later. Children who have been to preschool seem to stay in school longer, get better jobs, commit less crime, and require less welfare. The thing most of the early studies were looking for – academic ability – is one of the only things it doesn’t affect.
