“A full-time Ph.D. student is generally offered a standard financial aid package that can include tuition exemptions, coverage of medical fees, and a stipend.”

“The standard financial aid package offered to full‐time Ph.D. students who do not receive significant awards from outside sources consists of a stipend for four years (or five years for students entering the program in fall 2024 or later) and a tuition exemption for the student's two or three years of coursework”

“During the first year of coursework no service is required, but in all subsequent years during which students receive funding (i.e. years two through four or five) they will be assigned an assistantship that will require research or teaching.”
