A study to appear in October by MIT economist Joshua Angrist and University of Chicago business school professor Jonathan Guryan apparently says yes, according to this article. That's a counter-intuitive finding, of course; many reformers (ourselves included) have argued forever that tough teacher tests will deter poorly educated people from becoming teachers while attracting talented individuals. But maybe not. Here's how the scholars explain it:
First, they note, applicants whose educational backgrounds qualify them to teach are also likely qualified to work in other fields. When they weigh their job options, they calculate the cost in time, effort and money of the mandated tests as salary reductions.
"Higher quality applicants, as measured by outside earnings potential, are more likely to pass the test," Angrist says, but they're also more likely to want wages that will repay their efforts to take the tests. In addition, they're consumers; they can look for jobs at companies that don't require costly licensing tests.
Second, the discouragement effect, as economists call it, serves as a barrier to applicants broadly, Angrist notes. People who might be great teachers may choose not to study or pay for certification for myriad reasons, a loss for U.S. students in public schools.
I asked my podcast buddy, AEI's Rick Hess, about his thoughts on the study. Though it's not yet available for viewing, that didn't dissuade him from weighing in. (He could be a blogger!)
