Princeton University's School of Engineering and Applied Science (SEAS) occupies an unusual position among elite American engineering schools. It is small by the standards of its peers — roughly a quarter of Princeton's undergraduates pursue the Bachelor of Science in Engineering, a cohort measured in hundreds rather than thousands — and it sits inside a liberal-arts-oriented research university rather than alongside one. That structure shapes the experience of women studying engineering at Princeton in ways that matter for anyone comparing programs: smaller departments, closer faculty contact, a residential college system that builds community outside the major, and one of the most generous need-based financial aid programs in American higher education.
It is also a school that has made women's representation a visible institutional priority. In 2020, Princeton appointed Andrea Goldsmith — an electrical engineer with a distinguished research record in wireless communications — as the first woman to serve as dean of the engineering school, and recent entering BSE cohorts have reported women's enrollment approaching parity, a figure that places Princeton among the strongest of the Ivy League engineering programs on this measure and well above the national average for engineering bachelor's degrees, which has hovered in the mid-20-percent range according to federal data.
Enrollment and Representation
National context matters when reading any single institution's numbers. Women earn roughly a quarter of engineering bachelor's degrees in the United States, a proportion that has improved slowly over two decades. Against that baseline, Princeton's recent BSE classes — where women have made up roughly 40 percent or more of entering engineering students in several recent years — represent a meaningful departure from the national pattern, not a rounding difference.
The scale of the school amplifies the effect. Princeton SEAS comprises six departments: Chemical and Biological Engineering, Civil and Environmental Engineering, Computer Science, Electrical and Computer Engineering, Mechanical and Aerospace Engineering, and Operations Research and Financial Engineering. Several of these departments enroll fewer than a hundred undergraduates per class year, which means women students are rarely an isolated handful in a large lecture hall. Chemical and Biological Engineering and Civil and Environmental Engineering have historically enrolled women at or near parity, consistent with national patterns in those fields; Computer Science, by far the largest undergraduate concentration at Princeton, has seen women's enrollment rise substantially since the mid-2010s, though it remains below parity as it does nearly everywhere.
At the graduate level the picture is more uneven, again consistent with national trends. Women's representation among SEAS doctoral students varies considerably by department, and the school has directed recruiting attention at the PhD pipeline through visit days, fellowship nominations, and partnerships with organizations that reach women and underrepresented candidates earlier in their academic careers.
Leadership and Institutional Commitment
Goldsmith's deanship was significant beyond the symbolic milestone. Her tenure coincided with a major expansion of the engineering school — new buildings, faculty growth, and new institutes in bioengineering and quantum science — and with explicit public commitments to broadening participation in engineering. Princeton announced in 2025 that Goldsmith would depart to become president of Stony Brook University, and prospective applicants should check the school's current leadership when they apply; deans change, but the expansion she oversaw, including the new engineering neighborhood under construction on the east side of campus, is a long-term structural investment that will define the school for decades.
Institutionally, Princeton's engineering school benefits from university-wide diversity infrastructure: the Office of the Dean for Research, the Graduate School's recruitment programs, and Princeton's long-standing participation in consortia that support women and underrepresented students in doctoral study. These are the kinds of commitments that are easy to announce and hard to sustain; Princeton's record of sustained funding for them is part of why its enrollment numbers have moved.
Communities: SWE, GWiSE, and Princeton Women in CS
Princeton's Society of Women Engineers (SWE) section is the primary undergraduate community for women in engineering, running corporate networking events, conference travel to the national SWE conference, mentorship pairings between underclass and upperclass students, and outreach programming for local schools. For students weighing the financial side of an engineering degree, the national organization behind the Princeton section also administers one of the largest scholarship programs for women in engineering — covered in detail in our guide to SWE scholarships.
Graduate Women in Science and Engineering (GWiSE) serves the graduate population across STEM departments, with programming that addresses the distinct pressures of doctoral study: advisor relationships, conference presentation, academic job market preparation, and community among a smaller and more dispersed cohort. Princeton Women in Computer Science operates within the CS department specifically, reflecting that department's scale — CS is large enough at Princeton to sustain its own community infrastructure, study networks, and industry pipeline events.
The residential college system is an underappreciated structural advantage here. Every Princeton undergraduate belongs to a residential college with its own advising staff, which means a woman in mechanical engineering has an academic support structure that exists entirely outside her department. At larger engineering schools, students whose experience within the major turns difficult can find that the major is the only community they have; Princeton's structure makes that failure mode less likely.
Research Opportunities
Princeton's senior thesis requirement is the defining feature of its undergraduate academic program, and it applies to BSE students through senior independent work. Every Princeton engineering student completes a substantial independent research or design project with a faculty advisor — not as an option for the ambitious, but as a graduation requirement. For women considering doctoral study, this is worth weighing heavily: a year of independent research with a faculty member is precisely the experience that produces strong PhD applications and well-calibrated decisions about whether research is the right path.
Earlier research entry points include the ReMatch program, which pairs first-year and sophomore students with graduate student and postdoc mentors for summer research, and departmental summer programs funded through the school. Princeton faculty also host NSF Research Experiences for Undergraduates positions, and Princeton students compete successfully for REU placements elsewhere. The university's research infrastructure — including the Princeton Plasma Physics Laboratory, a Department of Energy national laboratory managed by the university — gives undergraduates access to research environments that few schools of any size can match.
Financial Aid
Princeton's financial aid program is among the most generous in the country and is frequently the deciding factor for admitted students comparing offers. Princeton was the first major American university to eliminate loans from its aid packages, replacing them entirely with grants, and its current aid policy covers full tuition, room, and board for most families with incomes up to $100,000 — with substantial aid extending well into six-figure family incomes. Admission is need-blind, including for international students, a policy almost no other university matches.
For women in engineering specifically, the practical consequence is that Princeton's BSE can cost dramatically less than an in-state public engineering program for families that qualify for aid, and graduates leave without debt. Students weighing outside scholarship applications should note that Princeton's aid interacts with external awards — external scholarships typically reduce the student contribution before touching the Princeton grant. Strategy for combining institutional aid with external awards is covered in our scholarship application strategy guide.
How Princeton Compares
Against the programs we have profiled previously, Princeton's distinctive offer is the combination of small scale, mandatory research, and aid generosity. MIT and Stanford offer larger engineering ecosystems with more course depth in any given subfield; Princeton offers closer faculty proximity and a guaranteed independent work experience. Carnegie Mellon's School of Computer Science reached gender parity in entering CS classes earlier than most peers and remains the benchmark for women in CS specifically. Students choosing among these schools are choosing among genuinely different models — and for students whose goal is doctoral study or research-track careers, Princeton's senior thesis model is a real differentiator.
What Princeton does not offer is an engineering-dominant campus culture. Engineers are a minority of Princeton undergraduates, and students who want to be surrounded entirely by engineering peers may prefer a dedicated technical institution. Many women students report the opposite preference — that a broad university culture moderates the intensity of an engineering cohort — but it is a matter of fit rather than ranking.
Frequently Asked Questions
What percentage of Princeton engineering students are women?
Recent entering BSE cohorts have reported women's enrollment at roughly 40 percent or higher, among the strongest figures in the Ivy League and well above the national average of roughly a quarter of engineering bachelor's degrees. Representation varies by department, with chemical and civil engineering historically nearest parity.
Does Princeton have a women-only engineering program?
No. Princeton's engineering degrees are coeducational, and there is no separate admissions track for women. Community infrastructure for women — the SWE section, Princeton Women in CS, and GWiSE at the graduate level — operates within the standard degree programs.
Is Princeton need-blind for engineering applicants?
Yes. Princeton admission is need-blind for all applicants, including international students, and the university meets full demonstrated need with grants rather than loans. Most families with incomes up to $100,000 pay nothing for tuition, room, and board under current policy.
Do Princeton engineering students have to do research?
Yes — senior independent work is a graduation requirement for BSE students, meaning every Princeton engineer completes a substantial faculty-advised research or design project. Earlier opportunities include the ReMatch mentorship program and summer research placements.
How does Princeton engineering compare to MIT or Stanford for women?
All three enroll women in engineering at rates well above the national average. Princeton's distinguishing features are its smaller scale, mandatory independent research, and no-loan financial aid; MIT and Stanford offer larger engineering ecosystems with greater subfield depth. The right choice depends on whether a student prefers a small program inside a liberal arts university or a large dedicated technical environment.
