NSF Graduate Research Fellowship Program
The National Science Foundation Graduate Research Fellowship Program (NSF-GRFP) is a grant awarded annually by the National Science Foundation to approximately 2,000 students pursuing research-based Master's and doctoral degrees in the natural, social, and engineering sciences at US institutions. As of 2024, the fellowship provides an honorarium of $16,000 to be placed towards the cost of tuition and fees at the university the fellow attends; it also awards the student directly with an annual $37,000 stipend for three years, leading to an anticipated total award amount of $159,000.
