Trying to improve the broken bar-exam system for licensing lawyers has been for too long like tilting at windmills while singing “The Impossible Dream.”

There is a disconnection between what the bar exam tests and what the American Bar Association and law schools require students to learn. Graduates must enroll in costly cram courses, forgo gainful employment for almost three months and incur collectively hundreds of millions of dollars in costs and lost income to survive the semiannual culling of the herd. Nor does the bar exam, which relies heavily on questions developed and scored by the National Conference of Bar Examiners, measure what one needs to know to be an effective lawyer.

Last July's historic nationwide drop in the bar passage rate brought into sharp focus the urgent need to overhaul a system that ill serves the public, the profession and certainly the graduates of our law schools. Over the past several months, fellow deans across the country have asked for a complete, credible and accurate explanation of the July 2014 results. We still are waiting.
