Not so much.
Taxpayers have been on the hook for more than $100 billion for the Head Start program since 1965. This federal evaluation, which effectively shows no lasting impact on children after first grade and no difference between those children who attended Head Start and those who did not, should call into question the merits of increasing funding for the program, which the Obama administration recently did as part of the so-called “stimulus” bill.
Here's the government's actual report--at least, the 35-page executive summary. Here's one of the closing statements:
In sum, this report finds that providing access to Head Start has benefits for both 3-year-olds and 4-year-olds in the cognitive, health, and parenting domains, and for 3-year-olds in the social-emotional domain. However, the benefits of access to Head Start at age four are largely absent by 1st grade for the program population as a whole.
Seven billion dollars a year is a lot of money to spend for benefits that don't last past 1st grade.
