How did full-time law professors change legal education in the United States?

The transition to a full-time faculty of scholars significantly transformed American legal education, moving it away from the previous model that relied on part-time instructors who were practicing lawyers.1

This shift, pioneered at Harvard University in the late 19th century, helped establish the university-based law school as the standard for professional training. By replacing part-time practitioners with full-time academics, law schools were able to implement more rigorous, standardized requirements, such as mandatory three-year programs and formal examinations.12

Furthermore, full-time professors were instrumental in developing the case method—a pedagogical approach introduced by Christopher Columbus Langdell that required students to analyze original legal authorities to derive principles for themselves. Over time, this professionalization of the faculty led to a greater emphasis on legal scholarship, with tenure standards in the United States increasingly aligning with those of other academic disciplines.213
