Harvard Researchers Question NCES Public-Private Analysis
August 7, 2006
Recently, the National Center for Education Statistics put out a study that claimed that private schools do not outscore public schools once student demographics are taken into account. A new analysis using different statistical controls yields a different outcome (link via Andrew Coulson).
"Our results are not offered as conclusive evidence that private schools outperform public schools but as a demonstration of the dependence of the NCES results on a questionable methodology," she added.
