Our conclusions differ importantly from those offered in some previous reviews because we use a more appropriate standard to judge the success of Head Start (namely, benefit-cost analysis), draw on new accumulating evidence for Head Start's long-term effects on early cohorts of program participants, and discuss why common interpretations of a recent randomized experimental evaluation of Head Start's short-term impacts may be overly pessimistic. While in principle there could be more beneficial ways of deploying Head Start resources, the benefits of such changes remain uncertain and there is some downside risk. ER -
