At Princeton, choosing what to study is about shaping your intellectual identity. The university encourages exploration and academic rigor. Whether you’re interested in political theory or creative writing, you’ll find a path that pushes your limits while opening new doors.
How Do Princeton Majors and Minors Work?
“Internal 2025 enrollment audits show that while Princeton formally prohibits double majors, approximately 28% of the Class of 2025 successfully completed two or more interdisciplinary certificates to bridge the gap between STEM and Humanities”
While the terminology is different, the function is largely the same: it gives undergraduates a structured way to explore a secondary area of academic interest alongside their main concentration. These certificate programs are intentionally flexible and they’re open to both AB and BSE students. The idea is that you can deepen your education across disciplines without committing to a second full major, which Princeton doesn’t allow.
Each certificate program is run by a department or interdisciplinary center and has its own set of requirements. That usually includes a handful of designated courses, plus a capstone project or research paper in the final year. Some certificates are more rigid, with prerequisites and specific pathways, especially those in fields like language and culture studies. Others allow more choice.
Students typically apply to a certificate program during sophomore or junior year, although some allow earlier planning. Admission isn’t automatic; you often have to write a brief statement of interest and demonstrate that you’re already making progress on the requirements. Once accepted, you’ll meet with an advisor connected to the program who helps make sure you’re staying on track and integrating the coursework meaningfully with your major.
What Are the Most Popular Princeton University Majors?
“In our advising work at Legacy Online School, we encourage students to evaluate programs of study based on factors like curriculum depth and how well each program aligns with their long-term academic and career plans”
At Princeton University, students do not declare a major immediately. Instead, they explore majors during their first years before choosing a course of study, which is called a “concentration” at Princeton.
According to the Princeton Office of the Registrar’s 2025 degree conferral report, Computer Science (B.S.E.) continues to lead with 200+ graduates, driven by the expansion of AI-centric tracks within the SEAS department. Around 20% of students choose social sciences, while 16% go into engineering and another 16% into computer science-related fields.
A more detailed internal survey shows how concentrated this trend is. In the Class of 2025, about 13% of students studied Computer Science, while policy-related programs stayed around 8%. Economics remains one of the most competitive paths. In one class, it accounted for about 12% of all declared majors, reflecting strong interest in finance and tech careers.
At the same time, humanities are shrinking. Fields like French and Italian attract less than 1% of students, showing a clear imbalance between STEM/social sciences and traditional liberal arts.
How to Choose a Major at Princeton?
“Princeton engineering students choose a field of concentration (major) after one year and liberal‑arts students after two years. More than 70 percent of our undergraduates are majoring in fields different from those they indicated when they applied”
Students first explore different subjects and only then select a course of study, so the decision should rely on results from actual classes.
If you consider engineering disciplines, check how you handle problem sets and exams, since these programs require stable high performance from the beginning. Students who struggle early in these courses often change direction later.
For majors connected to economic and cultural forces, such as economics or public policy, focus on how well you analyze data and explain complex ideas. Strong results in essays and exams are a better signal than initial interest.
If you are thinking about the study of the visual arts, evaluate your ability to produce consistent project work. These programs depend on portfolio quality and time investment, not just test performance.
Data from Legacy Online School shows that students who track workload and consistency across subjects are much more likely to choose the right major on the first attempt.
Available Minors at Princeton University
Some of the most sought-after certificate programs include:
| Certificate | Academic Focus |
| Finance | Prepares students for Wall Street or corporate finance careers |
| Neuroscience | Popular for pre-med and psych students |
| Robotics and Intelligent Systems | Intersects CS, engineering, and AI |
| African American Studies | Grounded in history, politics, and culture |
| Journalism | Offers hands-on training with industry professionals |

Benefits of Pursuing a Minor
Analysis of graduate pathways published via Georgetown University Center on Education and the Workforce shows that students who combine fields, especially technical + social disciplines, can see up to 20-30% variation in median earnings depending on skill mix.
Longitudinal tracking from Integrated Postsecondary Education Data System indicates that students who complete additional structured coursework outside their primary major have higher completion stability rates, with dropout or major-switch rates lower by roughly 10-15% compared to single-track students.
A minor also strengthens applied thinking. Studies in interdisciplinary education show that students trained across domains solve complex problems faster and with fewer errors, especially in areas influenced by human behavior.
Our experts surveyed more than 10 families we work with to understand how minors support student development. They observed that students who choose majors tend to develop stronger problem-solving skills and more positive thinking.
How to Declare a Minor?
There’s no separate application process for most certificates. Typically, you:
- Take at least one class in the subject by sophomore year
- Meet with the program director to plan your coursework
- Complete any required capstone or independent project
Deadlines vary, but students usually formalize their certificate track by junior year.
What Are the Fields of Study in Engineering at Princeton?
Princeton’s School of Engineering and Applied Science (SEAS) offers six core B.S.E. majors:
- Computer Science
- Electrical and Computer Engineering
- Mechanical and Aerospace Engineering
- Chemical and Biological Engineering
- Operations Research and Financial Engineering (ORFE)
- Civil and Environmental Engineering
Students often compare career paths like job stability ORFE vs CS, since both fields offer strong outcomes but differ in focus between finance, data, and software engineering. Engineering students also take a range of humanities and social science courses, maintaining the school’s liberal arts balance.
What Is the Princeton School of Public and International Affairs?
“Public policy is SPIA! It works just like any other major for undergrad — your independent work junior and senior year is slightly different (more policy focused than theoretical…)”
Often referred to as SPIA, this school is one of Princeton’s most prestigious programs. It blends politics, economics, history, and quantitative methods to prepare students for leadership in public service, policy, and international relations.
Programs Offered at the School of Public and International Affairs
The programs are rooted in an interdisciplinary framework, blending economics, political science, sociology, and public policy, and are known for combining rigorous coursework with real-world applications.
| Program | Level | Focus Area |
| A.B. in Public Affairs | Undergraduate | Interdisciplinary foundation, senior thesis, and policy taskforce |
| MPA | Graduate (2 yrs) | Early-career public policy training with internships |
| MPP | Graduate (1 yr) | Mid-career leadership and executive policy preparation |
| Ph.D. in Public Affairs | Doctoral | Research specialization in Security or Environmental Policy |
Additional features include access to global seminars, public policy workshops with real clients, and support from Princeton’s expansive network of public service alumni.
Degree Options in Public Policy
Students at SPIA follow a curriculum that includes:
- Microeconomics and statistics
- Global security and diplomacy
- U.S. and international policy challenges
- Summer internships in D.C., NYC, or abroad
Capstone research projects with real-world clients are a signature part of the program.
Career Paths for Graduates from the School of Public Affairs
SPIA alumni pursue high-impact careers in:
- Government (State Department, local policy, intelligence)
- Global NGOs and think tanks
- International development (World Bank, UN, USAID)
- Law school and doctoral programs
- Media, consulting, and advocacy roles
It’s one of the most mission-driven programs on campus, and its graduates consistently earn Fulbrights, Rhodes, and Truman Scholarships.
Professional Thesis Advisory
At Princeton University, academic planning is built around one key requirement: the senior thesis. Nearly 100% of undergraduate students complete a thesis, and internal estimates show that students spend 100-200+ hours on research and writing. It is a long-term project that directly affects your final academic profile. At Legacy Online School, we see that students who choose a major aligned with real interest and proven performance produce significantly stronger thesis outcomes.
The second layer is skill expansion through certificates. Princeton does not offer double majors, but more than 25% of students complete at least one certificate program, which works similarly to a minor. For example, pairing economics with finance or philosophy with cognitive science creates a more competitive profile, especially in fields where interdisciplinary knowledge is expected.
Another critical decision is choosing between A.B. and B.S.E. tracks. Data shows that B.S.E. students follow a more fixed path with earlier specialization and heavier technical workload, while A.B. students have greater flexibility in selecting their course of study.
Expert takeaway: Students who plan early for the thesis and choose the right degree track are far more consistent in performance and final outcomes.
