Coruscation

From 1989 to 2009, when college tuition rose by 71 percent, law school tuition shot up 317 percent.

There are many reasons for this ever-climbing sticker price, but the most bizarre comes courtesy of the highly influential US News rankings. Part of the US News algorithm is a figure called expenditures per student, which is essentially the sum that a school spends on teacher salaries, libraries and other education expenses, divided by the number of students.

Though it accounts for just 9.75 percent of the algorithm, it gives law schools a strong incentive to keep prices high. Forget about looking for cost efficiencies. The more that law schools charge their students, and the more they spend to educate them, the better they fare in the US News rankings.

"I once joked with my dean that there is a certain amount of money that we could drag into the middle of the school's quadrangle and burn," said John F. Duffy, a George Washington School of Law professor, "and when the flames died down, we'd be a Top 10 school. As long as the point of the bonfire was to teach our students. Perhaps what we could teach them is the idiocy in the US News rankings."

For years, it made economic sense for smart, ambitious 22-year-olds to pay the escalating price for a legal diploma. Law schools have had a monopolist's hold on the keys to corporate lawyerdom, which pays graduates six-figure salaries.

But borrowing $150,000 or more is now a vastly riskier proposition given the scarcity of Big Law jobs. Of course, that scarcity hasn't been priced into the cost of law school. How come? In part, it's because schools have managed to convey the impression that those jobs aren't very scarce.

For instance, although N.Y.L.S. is ranked No. 135 out of the roughly 200 schools in the US News survey, it asserts in figures provided to the publisher that nine months after graduation, the median private-sector salary of alums who graduated in 2009 -- which is the class featured in the most recent US News annual law school issue -- was $160,000. That is exactly the same figure cited by Yale and Harvard, the top law schools in the country.
