A common question we receive is “What kind of financial aid is available for PhD students?” and “How do I apply for financial aid if I am applying to the PhD program?”
Each student who is admitted to the PhD program is almost always fully funded by the admitting department, usually via a research or teaching assistantship. The exact terms of the award vary by department but they all include a 100% tuition/fee waiver plus a monthly stipend. (The stipend varies between departments so I cannot comment or guess how much the stipend is for any specific department.)
Accordingly, when you prepare your application for the PhD program, there is nothing additional that you will need to submit to be considered for financial aid … rather, focus on getting admitted – if you are admitted, financial support will follow.
