“No Benefits From 4k”

David Kiro:

There’s still no evidence that the children benefited cognitively from preschool. They may be better socialized to school life — a skill, emphasized in preschool, that may well bring long-term benefits — but many of them haven’t mastered the three Rs. That’s terrible news, since being a proficient reader by third grade is widely regarded as the best predictor of high school graduation.

Pre-K critics will again pounce on the results. “Devastating for advocates of the expansion of state pre-K programs,” wrote Russ Whitehurst, a senior fellow at the Brookings Institution, commenting on the first-round evaluation. It’s an “I told you so” moment for Tennessee State Representative Bill Dunn, who slammed his state’s prekindergarten as “like paying $1,000 for a McDonald’s hamburger.”

When a nationwide evaluation of Head Start, the federal government’s preschool program, reported similarly disappointing outcomes three years ago, Mr. Whitehurst delivered a blistering critique. “The best available evidence raises serious doubts that a large public investment in the expansion of pre-K for 4-year-olds will have the long-term effects that advocates tout.” Pre-K was generally thought to be better than Head Start, but that doesn’t seem to be the case in Tennessee.

Have the claims made for early education been overblown? Not necessarily. Consider what’s happening in Boston. A randomized study showed that prekindergartners there gained between four and seven months’ progress in reading and math, and those gains persisted: 27 percent more of Boston’s preschool children scored “proficient” or better on the state’s rigorous third-grade exams.
