High-Stakes Flimflam

Bob Herbert:

Not only has high-stakes testing largely failed to magically swing open the gates to successful learning, it is questionable in many cases whether the tests themselves are anything more than a shell game.

Daniel Koretz, a professor at Harvard’s Graduate School of Education, told me in a recent interview that it’s important to ask “whether you can trust improvements in test scores when you are holding people accountable for the tests.”

The short answer, he said, is no.

If teachers, administrators, politicians and others have a stake in raising the test scores of students — as opposed to improving student learning, which is not the same thing — there are all kinds of incentives to raise those scores by any means necessary.

“We’ve now had four or five different waves of educational reform,” said Dr. Koretz, “that were based on the idea that if we can just get a good test in place and beat people up to raise scores, kids will learn more. That’s really what No Child Left Behind is.”

The problem is that you can raise scores the hard way by teaching more effectively and getting the students to work harder, or you can take shortcuts and start figuring out ways, as Dr. Koretz put it, to “game” the system.

Guess what’s been happening?

“We’ve had high-stakes testing, really, since the 1970s in some states,” said Dr. Koretz. “We’ve had maybe six good studies that ask: ‘If the scores go up, can we believe them? Or are people taking shortcuts?’ And all of those studies found really substantial inflation of test scores.

“In some cases where there were huge increases in test scores, the kids didn’t actually learn more at all. If you gave them another test, you saw no improvement.”
