University scholarships and fellowships are available, providing funding for tuition and a stipend, in each case for four years. Details are included in the application materials. In addition, all students in good standing, regardless of the terms of the financial aid offered them at admission, are eligible to apply for dissertation-year fellowships, normally held in the fifth year of study.
Starting in the 2015-2016 academic year the Graduate School has moved to a system in which qualified students can obtain a sixth year of stipend funding. Sixth-year funding is available if the Department (in practice your dissertation supervisor and the DGS, through the Dissertation Progress Report) can guarantee that you are on track for dissertation submission in the summer following your sixth year. More information about sixth-year stipend funding can be found at http://gsas.yale.edu/funding-aid/faqs/sixth-year-funding-initiative-faqs
The department assigns teaching assistantships, normally in the third and fourth years. Travel grants for study and research abroad are available through the department. Students are also encouraged to apply for funding from the Graduate School, the Graduate Students Assembly and the MacMillan Center. All applicants should consider applying for national fellowships such as the Mellon and the Javits Fellowships. Students may borrow money under terms stipulated by the university and the Federal government.
