So asks Dan Mitchell in his excellent blog, International Liberty. He writes that Head Start is yet another costly government failure. By the government’s own research “the benefits of access to Head Start at age four are largely absent by 1st grade.” A follow on study looked at the same set of children at 3rd grade. It again concluded that Head Start is ineffective.
