The NSF GRFP has struggled with an uneven distribution of the award to a select few graduate schools. In 2019, 31% of the grants were awarded to students of only 10 elite academic universities, with 14% of them awarded to just the top three:
Berkeley,
MIT, and
Stanford. This distribution has been suggested to perpetuate inequality in science, as graduate students at less elite academic universities often have a greater need for funding. In addition, elite universities, both graduate and undergraduate level, often have greater resources designed to help students submit successful applications. Awareness of the fellowship, resources to help apply, research opportunities in undergrad, financial freedom to work in a lab in college, and undergraduate support are also important factors considered contributors to an uneven distribution. Between 2019 and 2021, the distribution has favored the so-called "elite" institutions less, with the top ten's share dropping to 26% and the share of the top three dropping to 12%. An alternative explanation is that the students awarded the GRFP, who come from many different social and economic backgrounds, naturally gravitate towards the best nationwide institutions for research. The GRFP often vastly increases awardee's academic freedom to choose between labs and universities, since they are less reliant on departmental funding. Until 2016 the NSF GRFP allowed any number of applications before starting graduate school, and two applications once enrolled. In 2016 the NSF reduced the number of times an enrolled graduate student could apply to only once during their graduate career. Between 2015 and 2021, Berkeley (504), MIT (440), and Cornell (271) were the top universities from which fellows received undergraduate degrees; the top three universities affiliated with graduate students receiving NSF-GRFP awards were Berkeley (758), Stanford (634), and MIT (531). ==Application requirements==
