DATA: BY THE TIME YOU START TEACHING YOUR CHILD IT'S TOO LATE http://www.usatoday.com/printedition/news/20050504/oplede04.art.htm
STEPHEN J. DUBNER AND STEVEN D. LEVITT, USA TODAY - The U.S. Department of Education recently undertook a monumental project called the Early Childhood Longitudinal Study, which tracks the progress of more than 20,000 American schoolchildren from kindergarten through the fifth grade. Aside from gathering each child's test scores and the standard demographic information, the ECLS also asks the children's parents a wide range of questions about the families' habits and activities. The result is an extraordinarily rich set of data that, when given a rigorous economic analysis, tells some compelling stories about parenting technique.
A child with at least 50 kids' books in his home, for instance, scores roughly 5 percentile points higher than a child with no books, and a child with 100 books scores another 5 percentile points higher than a child with 50 books. . .
But the ECLS data show no correlation between a child's test scores and how often his parents read to him. How can this be? Here is a sampling of other parental factors that matter and don't:
Matters: The child has highly educated parents.
Doesn't: The child regularly watches TV at home.
Matters: The child's parents have high income.
Doesn't: The child's mother didn't work between birth and kindergarten.
Matters: The child's parents speak English in the home.
Doesn't: The child's parents regularly take him to museums.
Matters: The child's mother was 30 or older at time of the child's birth.
Doesn't: The child attended Head Start.
Matters: The child's parents are involved in the PTA.
Doesn't: The child is regularly spanked at home. . .
It is obvious that children of successful, well-educated parents have a built-in advantage over the children of struggling, poorly educated parents. Call it a privilege gap. The child of a young, single mother with limited education and income will typically test about 25 percentile points lower than the child of two married, high-earning parents.
So it isn't that parents don't matter. Clearly, they matter an awful lot. It's just that by the time most parents pick up a book on parenting technique, it's too late.
