Folks at Goldwater Institute in Phoenix have long been opponents of publicly financed pre-kindergarten. They're out with a new analysis that says the investment in early childhood education the state is making is a waste of money. It says that the small positive effects of full-day kindergarten fade by fifth grade. The study is odd, though. It seems to treat pre-kindergarten and full-day kindergarten interchangeably. It also does not use individual data and it is silent on the quality of the half-day pre-kindergarten programs in the state. In short, only a researcher who set out to find no effect from pre-kindergarten would rely on the study's methodology. Oh and, no surprise here, school choice is a big winner!
