This guest post is an open letter in response to The Wall Street Journal editorial “Head Start for All.”
Your review claims that the Perry study and the Abecedarian study are the sole evidence that preschool works. But they are just the best known of a large number of studies finding that preschool works, that is, has its intended effects on children. Along with the city-wide Chicago Child-Parent Centers study, these studies go a big step further by finding strong long-term effects and return on investment.
In the presence of large returns on investment, the initial cost should be a secondary consideration. That said, the Perry Preschool cost per child was well below the $16,000 per child per year or more you said it cost. In current dollars, it cost $11,107 per child per year, about the same as the cost per K-12 student in the U.S. The Perry Preschool program is not that hard to replicate—and have its return on investment widely realized. We simply need to insist on reasonable program standards – qualified teachers using a proven curriculum, partnership with parents, and regular evaluation. Unfortunately, far too many existing preschool programs do not meet these standards.
The disappointing results of the national Head Start Impact Study are hardly a reason to abandon the program when other studies, like the Perry Preschool Study, show its enormous potential. The Head Start Impact Study does suggest a course correction, bringing the resources of Head Start more fully to bear on contributing to the development of young children living in poverty. Such improvements are achievable and, with them, widespread improvements in educational achievement, economic productivity, and reduced costs to taxpayers.
