Washington University School of Law offers many joint-degree options in collaboration with the university's other highly respected graduate schools. Students can design a joint degree to meet their individual interests by combining law with another master's program at the university. The School of Law and the participating departments work together so that a student can earn a Juris Doctoris (JD) and a master's or doctoral degree in another discipline in considerably less time than they would need to pursue each degree separately.

Applicants must gain admission to each program independently and therefore might need to take separate entrance exams (e.g., the Graduate Record Examination or the Graduate Management Admission Test) in addition to the Law School Admission Test.

The School of Law accepts up to 9 credit units earned in the other divisions toward the JD degree, as long as the JD is finished at the same time or immediately after the master's degree. The other divisions accept varying amounts of credit earned in the law school toward the master's degree.
