"When she found that metro areas with more streams tended to have more districts, and also higher student achievement, many academics thought she had come up with an ingenious way of testing Dr. Friedman's competition thesis. 'Caroline had a great idea with that paper,' says David Figlio, an education economist at the University of Florida. 'It is incontrovertible that it was a brilliant insight.'
Dr. Rothstein says it doesn't stand up to scrutiny. He makes several technical challenges, but his main attack is on the way the author counted streams."
How about worrying about the results of the study? Some schools are better than others and many parents are not allowed to choose where their kids go. That's wrong!
