The candidate must be formally admitted to his or her degree program.

The normal residency requirement is the equivalent of three Academic Years of full-time study beyond the bachelor's degree. Students who enter a PhD program at Brown already holding a master’s degree in a related field have a residency requirement equivalent to two Academic Years of full-time study upon entering the PhD program at Brown. Use of a previously earned master’s degree to reduce PhD residency requirements is contingent upon approval of the program Director of Graduate Study.

Graduate work done at other institutions and not used in fulfillment of the requirements for any doctoral degree elsewhere may, on the approval of the program Director of Graduate Study, be counted in fulfillment of up to, but not exceeding, one year of the residency requirement. A student who desires credit for work done elsewhere should file a timely application with the program Director of Graduate Study; transfer credit forms are available through the Office of the Registrar.

A student is advanced to candidacy for the Ph.D. when he or she has completed satisfactorily all the requirements, departmental and general, requisite to beginning work on the dissertation. Candidacy is determined by the department or program of study and certified by the Registrar. Most departments require a preliminary examination before advancing any student to candidacy. Most departments also require a final examination or defense. The examination is conducted by professors in the department and by such other members of the faculty as may be appointed.

The candidate must present a dissertation on a topic related to his or her area of specialization that presents the results of original research and gives evidence of excellent scholarship. The dissertation must be approved by the professor or committee under whose direction it is written and by the Graduate Council. All requirements for the Ph.D. must be completed within five years after advancement to candidacy.
