Non-J.D. enrollment has increased 79% over the last 15 years
For most of the last four decades, enrollment in non-J.D. programs (especially LL.M.s) has been relatively flat, usually somewhere between 5,000 and 6,000 students. But as the turn of the century approached, non-J.D. enrollment steadily increased before spiking 45% from 2006 to 2013. Increasingly, law schools are turning to these programs to generate much-needed revenue as J.D. programs flounder and J.D. graduates seek additional credentials to compete with peer J.D.'s.
Note that in the 1960's and early 1970's, non-J.D. enrollment looked much different as a percentage of total enrollment. We suspect much of this has to do with the transition from LL.B. to J.D. as the primary professional degree offered by U.S. law schools.
