J.D. Degree

Since enrolling its first class in 1865, The George Washington University Law School has produced some of the finest minds across the spectrum of legal scholarship. That tradition continues today, as GW Law graduates use the knowledge and skills they gain here to influence the critical legal conversations of our times.

Princeton University is a vibrant community of scholarship and learning that stands in the nation's service and in the service of all nations. Chartered in 1746, Princeton is the fourth-oldest college in the United States. Princeton is an independent, coeducational, nondenominational institution that provides undergraduate and graduate instruction in the humanities, social sciences, natural sciences and engineering. As a world-renowned research university, Princeton seeks to achieve the highest levels of distinction in the discovery and transmission of knowledge and understanding. At the same time, Princeton is distinctive among research universities in its commitment to undergraduate teaching. Today, more than 1,100 faculty members instruct approximately 5,000 undergraduate students and 2,500 graduate students. The University's generous financial aid program ensures that talented students from all economic backgrounds can afford a Princeton education.

The George Washington University actively engages Washington, D.C., and the world. Their location in the heart of Washington places them at the core of U.S. government, policy and law. They sit where the worlds of science, technology, media and the arts converge. Their students and faculty have the unparalleled opportunity to study and work alongside leaders and practitioners in every discipline, to take part in the interchanges that shape our community and the world. The George Washington University was created in 1821 through an Act of Congress, fulfilling George Washington’s vision of an institution in the nation’s capital dedicated to educating and preparing future leaders. Today, GW is the largest institution of higher education in the District of Columbia. They have more than 20,000 students—from all 50 states, the District and more than 130 countries—studying a rich range of disciplines: from forensic science and creative writing to international affairs and computer engineering, as well as medicine, public health, the law and public policy. GW comprises three campuses—Foggy Bottom and Mount Vernon in Washington, D.C., and the GW Virginia Science and Technology Campus in Ashburn, Va.—as well as several graduate education centers in the metropolitan area and Hampton Roads, Va.
