What Is the Difference Between a JD, LLM, and SJD?
JD, LLM, and SJD may all be awarded by U.S. law schools, but they serve completely different educational and career goals.
The JD is the foundational degree for legal professional education in the United States; the LLM is usually an advanced master's degree for people who already have a legal education; the SJD or JSD is an advanced research doctorate centered on original legal scholarship.
JD: The Core Degree for Legal Professional Education in the United States
JD stands for Juris Doctor. Applicants usually need to have completed an undergraduate degree first, but the undergraduate major does not have to be law. Students from engineering, finance, history, computer science, and language programs can all apply.
A full-time JD generally takes three years. The first year often includes contracts, torts, civil procedure, criminal law, property, constitutional law, and legal research and writing; in later years, students can take electives such as corporate law, tax law, intellectual property, and immigration law, and participate in legal clinics, moot court, journals, and internships.
In the United States, most students who plan to become lawyers through the standard pathway complete a JD. The ABA accreditation system mainly applies to JD programs as the first law degree. At present, the ABA has approved nearly two hundred programs that can award the JD.
LLM: Advanced Study for Those Who Already Have Legal Education
LLM stands for Master of Laws. Most U.S. LLM programs require applicants to already have a first law degree, such as a U.S. JD, a British LLB, or a recognized law degree from another country. The program is usually one year full-time, but this varies by school and specialization.
LLM programs can be divided into two broad directions. The first is for foreign law graduates and helps them study the U.S. legal system; the second is a specialized LLM, such as tax law, intellectual property, international law, or financial law.
An LLM is not a "shortened JD." Its course of study is shorter, and it also usually lacks the full three-year campus recruiting cycle available to JD students. Whether completing an LLM allows a student to sit for the Bar Exam depends on the target state and the applicant's original legal education.
Different schools also position their LLM programs differently. For example, Yale Law School explains that its LLM is a one-year full-time program mainly intended for people who aspire to legal teaching and research, and is not specifically designed for New York Bar preparation.
SJD or JSD: A Doctorate in Legal Research
SJD stands for Doctor of Juridical Science. Some schools write it as JSD, meaning Doctor of the Science of Law. The word order differs, but the terms usually refer to the same type of advanced legal research degree.
The SJD/JSD focuses on original legal research, dissertation writing, and a future academic career. It is not a required degree for practicing law. Applicants usually have already completed an LLM and need to submit a mature research proposal, writing samples, and academic recommendations.
Taking Yale as an example, JSD applicants are expected to have performed exceptionally well during the LLM and to show potential for high-level scholarly research; degree requirements include completing a dissertation that makes a substantial original contribution to legal scholarship. Admission does not happen automatically because someone has earned an LLM.
Differences Among the Three for Lawyer Qualification
JD graduates usually have the broadest educational eligibility for the Bar Exam across U.S. states, but they still must meet the exam requirements and Character and Fitness requirements of the target state.
After completing an LLM, foreign law graduates may become eligible to sit for the exam only in some states and only after meeting specific course and original-education requirements. An LLM does not automatically grant eligibility for the Bar Exam nationwide.
The SJD mainly demonstrates research ability. Having an SJD does not replace the first legal education required by the target state, nor does it automatically lead to a law license.
How Should You Choose?
Non-law undergraduates who want to study U.S. law systematically and practice in the United States long term usually consider the JD.
Those who already have a law degree from China or another country and want to study U.S. law, specialize in a particular field, or assess eligibility for the Bar Exam in a specific state can consider the LLM.
Those who have already completed a high-level master's degree in law and want to become law professors or conduct original legal research can consider the SJD/JSD.
These three degrees are not a simple "undergraduate-master's-doctorate" progression. Although the JD is named a Doctor, it is the first degree in U.S. professional legal education; the LLM is a master's degree in law; and the SJD/JSD is the research-oriented legal doctorate centered on an original dissertation. The choice should start from career goals, not simply from which degree appears to have a "higher level" in its name.
