Princeton’s full-funding guarantee ensures total support for all Ph.D. students throughout regular program enrollment. This includes tuition and stipend support from fellowships, assistantships, and external sources. Visit our Financial Support Model page for information about tuition & costs. Fellowships Fellowships are the primary source of funding in Princeton’s financial support model for degree candidates in the humanities and social sciences. All students during their regular enrollment period are covered fully via a University Fellowship, unless they hold alternate sources of funding. Additional fellowships are also offered by the Graduate School and campus partners, some of which offer a higher stipend rate. Premium-rate honorific fellowships are awarded to select later-stage Ph.D. students whose research shows exceptional promise. Explore Princeton Fellowships Assistantships & External Fellowships Additional funding comes in many forms, including assistantships and external fellowships. Assistantships Most Ph.D. programs require teaching during regular enrollment, often in specific years of study. AIs include a tuition and stipend component, the latter of which is higher than the base University Fellowship. Support from an AI replaces, in full or in part, any funding provided from the University. Partial appointments are prorated according to the percentage AI assigned. Students may also be offered Assistantships in Research (ARs). External Fellowships In addition to fellowships sponsored by the Graduate School and campus partners, many students land competitive national and international fellowships from external sources, including from the U.S. Fulbright Program, the Ford Foundation, and others. Dissertation Completion Funding If the degree is not completed within a department's normal timeframe, up to two additional years of dissertation completion enrollment (DCE) may be available. In general, DCE students are not guaranteed support. However, it is provided in certain circumstances and supplemental funding can be found from a variety of sources. The Office of the Dean of the Graduate School offers a sixth-year-funding program to select Ph.D. students in the humanities and social sciences.
