For students who hold a J.D. from a law school in the United States or Puerto Rico, and who are hoping to embark on a law teaching career, the emphasis is slightly different. These students have the opportunity to take a step back and relate the doctrinal areas in which they previously concentrated to broader intellectual, social, and cultural traditions and to pursue an extended writing project. Thus, students from the United States and Puerto Rico are strongly encouraged to take at least one course that is primarily focused on legal theory or jurisprudence and are required to write a paper of at least 50 pages in length.
