Legal diplomas are apparently losing luster.

The organization behind the Law School Admission Test reported that the number of tests it administered this year dropped by more than 16 percent, the largest decline in more than a decade.

The Law School Admission Council reported that the LSAT was given 129,925 times in the 2011-12 academic year. That was well off the 155,050 of the year before and far from the peak of 171,514 in the year before that. In all, the number of test takers has fallen by nearly 25 percent in the last two years.

The decline reflects a spreading view that the legal market in the United States is in terrible shape and will have a hard time absorbing the roughly 45,000 students who are expected to graduate from law school in each of the next three years. And the problem may be deep and systemic.

Many lawyers and law professors have argued in recent years that the legal market will either stagnate or shrink as technology allows more low-end legal work to be handled overseas, and as corporations demand more cost-efficient fee arrangements from their firms.
