Redshirting Kindergartners

Here's a story from today's Slate magazine about redshirting kindergartners.

"In addition, the trend toward older kindergarten among well-off families may be fueling the trend toward state laws that delay kindergarten for everyone. As Elizabeth Weil noted in a great piece on redshirting in the New York Times Magazine last year, almost half the states have pushed back their birthday cutoffs since 1975, several of them fairly recently."

"It's easy to see what the states are up to: They're worried about test scores, and they figure that older kids plus academic kindergarten will produce better ones."

"The increasing availability of public pre-K becomes, then, not the additional year of school that early childhood educators and advocates wanted for families that can't afford private preschool. Instead, pre-K, when it's offered, just replaces what the first year of kindergarten used to be."

""There is no evidence of a lasting benefit to education or earnings from being older than one's classmates," they (Deming and Dynarski) write. Another recent study, by Sandra Black of UCLA, crunched data from Norway and actually found a small boost in IQ for starting school early, but little effect on educational attainment—how well kids do in school in the long run. The place where redshirting is a proven advantage is the sports field. For example, 60 percent more Major League Baseball players are born in August than in July, and the birthday cutoff for youth baseball is July 31. But athletics, Dynarski points out, isn't academics."
