It was unsurprising to hear, as we did Tuesday, that Claremont McKenna College had lied about its students’ SAT scores to boost its position in the U.S. News & World Report annual ranking of colleges. University officials are famously obsessed with these rankings, and this is not the first time that a school has admitted fudging data. Just last year, Villanova Law School said that it had given false information to U.S. News.

Today we quantify and rank the performance of people and institutions as never before – all in pursuit, supposedly, of better outcomes and greater efficiency. Yet this obsession with metrics, a hallmark of the free-market ideology, invariably creates more incentives to cheat.

University presidents fret endlessly about the U.S. News rankings because they can have dramatic effects on everything from the quality of student applicants to the ability of schools to attract faculty and raise money. In an earlier era, one free of U.S. News, schools would not have had much reason to lie about SAT scores or admission rates. But now, with these numbers seen as hugely important, you can understand the temptation to monkey around with the reported data.

It’s not just colleges. Metrics have also taken over our K-12 schools, and they’re worse off for it. The education world has been roiled by major scandals recently in which administrators and teachers have been found to have manipulated student scores on standardized tests. These have not been isolated incidents, with revelations of false reporting in Atlanta, Chicago, Washington, Birmingham, New York City and Los Angeles.

It’s no secret why so many teachers and administrators are fudging test numbers: The pressure surrounding high-stakes testing is evident enough in the phrase itself. Tests now determine how schools are funded and, in some places, which teachers get bonuses. Incentives to cheat are baked into this system, and those incentives will only grow if more localities link teacher performance to compensation.
