Today millions of American children grow up in homes where they don't learn the skills they need to succeed in life. Their vocabularies are tiny. They can't regulate their emotions. When they get to kindergarten they've never been read a book, so they don't know the difference between the front cover and the back cover.
But, starting a few decades ago, we learned that preschool intervention programs could help. The efforts were small and expensive, but early childhood programs like the Perry and Abecedarian projects made big differences in kids' lives. The success of these programs set off a lot of rhapsodic writing, including by me, about the importance of early childhood education. If government could step in and provide quality preschool, then we could reduce poverty and increase social mobility.
But this problem, like most social problems, is hard. The big federal early childhood program, Head Start, has been chugging along since 1965, and the outcomes are dismal. Russ Whitehurst of the Brookings Institution summarizes the findings of the most rigorous research: "There is no measurable advantage to children in elementary school of having participated in Head Start. Further, children attending Head Start remain far behind academically once they are in elementary school. Head Start does not improve the school readiness of children from low-income families."
Fortunately, that is not the end of the story. Over the past several years, there's been a flurry of activity, as states and private groups put together better early childhood programs. In these programs, the teachers are better trained. There are more rigorous performance standards. The curriculum is better matched to the one the children will find when they enter kindergarten.
These state programs, in places like Oklahoma, Georgia and New Jersey, have not been studied as rigorously as Head Start. There are huge quality differences between different facilities in the same state or the same town. The best experts avoid sweeping conclusions. Nonetheless, there's a lot of evidence to suggest that these state programs can make at least an incremental difference in preparing children for school and in getting parents to be more engaged in their kids' education.
These programs do not perform miracles, but incremental improvements add up year by year and produce significantly better lives.
Enter President Barack Obama. Last week he announced the most ambitious early childhood education expansion in decades. On Thursday morning, early education advocates were sending each other ecstatic emails. They were stunned by the scope of what Obama is proposing.
But, on this subject, it's best to be hardheaded. So I spent Wednesday and Thursday talking with experts and administration officials, trying to be skeptical. Does the president's plan merely expand the failing federal effort or does it focus on quality and reform? Is the president trying to organize a bloated centralized program or is he trying to be a catalyst for local experimentation? So far the news is very good. Obama is trying to significantly increase the number of kids with access to early education. The White House will come up with a dedicated revenue stream that will fund early education projects without adding to the deficit. These federal dollars will be used to match state spending, giving states, many of whom want to move aggressively, further incentive to expand and create programs.
But Washington's main role will be to measure outcomes, not determine the way states design their operations. Washington will insist that states establish good assessment tools. They will insist that pre-K efforts align with the K-12 system. But beyond that, states will have a lot of latitude.
