Several colleges and universities are pausing admissions to some graduate programs, reducing class sizes or rescinding offers to students in an effort to cut costs amid uncertainty in federal funding.

The disruption to graduate school admissions is the latest cost-cutting move for colleges. After the National Institutes of Health proposed cutting reimbursements for costs related to research, several colleges and universities said they would pause hiring and cut spending, Inside Higher Ed previously reported. (A federal judge has blocked the NIH plan from taking effect for now.)

In recent days, the University of Pittsburgh, the University of Pennsylvania and several other institutions have stopped doctoral admissions, at least temporarily. Some colleges are pausing admissions to some programs such as in the biomedical sciences, Stat News reported. At others, the pause is universitywide. The University of Southern California and Vanderbilt University temporarily paused graduate student admissions, though both universities later said that they’d ended the pause.

A University of Pittsburgh spokesperson told WESA, a local NPR station, that the university “temporarily paused additional Ph.D. offers of admission until the impacts of that [NIH] cap were better understood … the University is in the process of completing that analysis and expects to be in a position to resume offers soon.”

Meanwhile, the University of Pennsylvania is planning to cut graduate admissions rates, The Daily Pennsylvanian reported, citing an email from the interim dean of the School of Arts and Sciences, Jeffrey Kallberg, who wrote that the cuts were a “necessary cost-saving measure” to adjust to the NIH proposal.

“This is not a step any of us wanted to take,” Kallberg wrote, according to the Daily Penn. “We recognize that graduate students are central to the intellectual life of our school—as researchers, teachers, collaborators, and future scholars. However, we must ensure that we can continue to provide strong support for those students currently in our programs and sustain the school’s core teaching and research activities.”

Tom Kimbis, executive director of the National Postdoctoral Association, wrote in an email to Inside Higher Ed that academic institutions reliant on federal funding “are being forced to make tough decisions to support these researchers in a difficult environment.”

“The decisions in Washington to pause or cease funding for science and research is impacting early-career researchers across a wide range of disciplines,” Kimbis added. “Slowing or stopping their work, on topics from cancer and Alzheimer’s research to social science issues, hurts Americans in all 50 states.”

In the last week, some faculty began tracking the reductions in the biomedical sciences via a shared spreadsheet that includes verified cuts and unverified decisions based on word of mouth and internal emails. Faculty on social media said the cuts will have long-term ramifications for sciences as fewer students enter the field. On TikTok, several students who had applied to grad school shared their dismay at how the funding cuts meant they might have to say goodbye to their career plans and research.

Accepting graduate students, particularly for Ph.D. programs and in the biomedical sciences, requires universities to make a long-term financial commitment, which is more difficult now that the NIH has stopped making new grant awards and is aiming to cut funds. Colleges receive billions from the NIH to support research. If the proposed rate cuts move forward, institutions say they would have to shut down some labs and lay off employees.

“University research and scholarship operate on a time scale of years and decades,” the Rutgers AAUP-AFT chapter wrote in a letter to New Jersey senators Cory Booker and Andy Kim. “Higher education would become impossible in the face of capricious and arbitrary withholding of funding, elimination of entire areas of grant support for critical scientific research, and cancellation of long-held contracts.”

They went on to warn that the threat to funding would diminish the country’s strength as a research superpower. “The best scientists, the best scholars, and the best students will make the rational decision to take their talents elsewhere. Once lost, the historic excellence of United States universities, including world-leading institutions in New Jersey, both public and private, will not be easily regained.”
