Princeton BSE Engineering Program Guide 2026

Princeton BSE Program Overview

Princeton University’s School of Engineering and Applied Science (SEAS), founded in 1921, offers one of the most rigorous and distinctive undergraduate engineering programs in the world. The Bachelor of Science in Engineering (BSE) degree is built on a philosophy that engineering excellence requires broad intellectual foundations, combining deep technical training with a substantial liberal arts education that few peer institutions can match.

The BSE program requires 36 courses over four years, including at least seven humanities and social science electives spanning four distribution areas. This unique structure ensures that Princeton engineers graduate not only with technical mastery but also with the critical thinking, communication, and ethical reasoning skills that define effective leaders in every field. Whether you dream of designing autonomous systems, developing sustainable infrastructure, or launching a technology startup, the Princeton BSE equips you with an unmatched foundation.

Accredited by the Engineering Accreditation Commission of ABET across five of its six departments, Princeton’s engineering program meets the highest professional standards while maintaining the flexibility for students to chart their own academic path. The university itself holds accreditation from the Middle States Commission on Higher Education, reinforcing its commitment to academic excellence across all disciplines.

Six Engineering Departments and Majors

One of the defining features of the Princeton BSE experience is the common first-year curriculum. Rather than locking students into a department from day one, Princeton allows all engineering students to share the same foundational courses during their first year. Students declare their major at the end of spring term, after they’ve had time to explore the six departments through coursework, open houses, and informal conversations with faculty and upperclassmen.

The six BSE departments each offer distinct paths to engineering mastery:

• Chemical and Biological Engineering (CBE): Focuses on molecular-level processes, thermodynamics, and biological systems. Core courses include CBE 245, 246, 250, 341, 346, 441, and 442, with a required senior thesis (CBE 454). Students take additional chemistry and molecular biology courses, making this ideal for those interested in pharmaceuticals, materials science, or biotechnology.
• Civil and Environmental Engineering (CEE): Offers five distinct tracks — Structural, Environmental, Architectural, Geological, and Engineering and Liberal Arts. The two-term senior thesis (CEE 478) emphasizes real-world project design, from earthquake-resistant structures to water purification systems.
• Computer Science (COS): Princeton’s COS department, housed in its dedicated building since 1989, offers the BSE track with core courses in algorithms (COS 226), systems (COS 217), and reasoning (COS 240). Students choose from areas including theoretical CS, computer systems, and AI/ML.
• Electrical and Computer Engineering (ECE): Covers circuits, signals, semiconductor devices, and computer architecture. The required two-term senior thesis (ECE 497-498) allows deep research into areas from quantum computing to wireless communications.
• Mechanical and Aerospace Engineering (MAE): Students can pursue Aerospace Engineering, Mechanical Engineering, or both. The curriculum spans dynamics, fluid mechanics, materials, structures, and three required design courses that turn theory into practice.
• Operations Research and Financial Engineering (ORFE): A uniquely Princeton department that applies mathematical modeling, statistics, and optimization to problems in finance, logistics, and decision-making. With 10-11 departmental electives, ORFE offers exceptional flexibility.

First-Year BSE Curriculum Requirements

The Princeton BSE first-year curriculum is carefully designed to build the mathematical, scientific, and computational foundations that every engineer needs, regardless of their eventual department. First-year students take four courses in the fall semester and five in the spring, for a total of nine courses.

The fall term typically includes physics (choosing from Physics 103, 105, EGR 151, or the integrated ISC 231-232 sequence), mathematics (Math 103, 104, or 201 depending on placement), chemistry (Chemistry 201 or 207, or the new MOL 214 option starting with the Class of 2026), and either a Writing Seminar or a humanities/social science elective.

The spring term expands to five courses: the next course in the physics and math sequences, Computer Science (COS 126 or ECE 115), a Writing Seminar (if not taken in fall), and humanities/social science electives. Students headed toward CBE or pre-medical tracks should also take Chemistry 202 in the spring.

This common curriculum means that switching departments after first year is straightforward — there’s no need to “start over” because every BSE student has completed the same foundational coursework. The system encourages genuine exploration and informed decision-making rather than premature specialization.

Math and Science Placement Guide

Correct placement in math and physics is one of the most consequential decisions first-year BSE students make. Princeton offers multiple entry points in both subjects, calibrated to students’ prior preparation and academic ambitions.

Mathematics placement begins with your AP or equivalent background. Students without AP credit start at Math 103. Those with one unit of AP credit (AB Calculus or equivalent) begin at Math 104. A BC Calculus score of 5 qualifies students for Math 104 (the department recommends this even for strong students, though those with demonstrated Taylor series mastery may petition for Math 201). Students who have already studied multivariable calculus need written permission from the Math AP Officer to place out of 201. Important restrictions: Math 175 is not allowed for BSE students, and Math 214/215 do not satisfy BSE requirements.

Physics placement offers four distinct pathways. The mainstream sequence (Physics 103→104) suits students with high school physics and calculus. Physics 105→106 provides a more theoretical approach for students with keen physics interest. The engineering-motivated EGR 151→153 sequence is designed specifically for first-year BSE students who have not taken AP Physics or multivariable calculus. The most ambitious path is the Integrated Science Curriculum (ISC 231-234), a rigorous four-course sequence that satisfies physics, chemistry, and computing requirements simultaneously — ideal for students with multivariable calculus placement and exceptionally strong science backgrounds.

Chemistry requires one term of general chemistry for most BSE students, satisfied by AP credit, Chemistry 201, Chemistry 207, or MOL 214. CBE majors and pre-med students need a second semester (Chemistry 202 or 215). Chemistry 207 is the mainstream choice for BSE students, covering general chemistry with an engineering perspective.

Department Course Maps and Specializations

After the common first year, each department’s curriculum diverges significantly. Understanding these course maps early helps students plan their four-year trajectory, including summer courses, study abroad windows, and certificate programs.

Chemical and Biological Engineering students face one of the most structured paths. Beyond the seven CBE core courses, they must complete CHM 301, CHM 302 (or an advanced chemistry elective), MOL 214/215, MAE 305, and four to five program electives — at least two of which must come from engineering departments (CBE, CEE, COS, EGR, ELE, MAE, or MSE). An advanced CBE course beyond the core is also required. The senior thesis (CBE 454) is the capstone experience.

Civil and Environmental Engineering offers remarkable diversity through its five tracks. The Structural track emphasizes mechanics, structural analysis, and design (CEE 205, 262A, 306, 312, 361, 364-366, 461). The Environmental track focuses on water, air, and ecosystem engineering (CEE 205, 207, 302/304, 305, 306, 308, 311, 364, 471, 477). Both tracks share GEO 203, ORF 245, and MAE 305 as additional requirements, plus three or more program electives. The two-term senior thesis (CEE 478) is central to the CEE experience.

Computer Science BSE (effective Class of 2025) builds on a four-course core: COS 126, 217, 226, and 240. Students then satisfy four area requirements — Theoretical CS (e.g., COS 423, 433, 445), Computer Systems (e.g., COS 316, 375), AI/ML (e.g., COS 324, 424, 429), and a Breadth elective (e.g., COS 326, 333, 343). Three additional 300+ level COS electives and independent work (COS 397/398/497/498) round out the program.

Electrical and Computer Engineering centers on ECE 201, 203, 206 (or 308), and 302. Students then take upper-level math, non-ECE engineering science, and design courses beyond 302. The required two-term senior thesis (ECE 497-498) allows deep exploration of topics from photonics to embedded systems.

Mechanical and Aerospace Engineering is built on a six-course core (MAE 206, 221-224, MAE 305), five engineering science courses spanning dynamics/control, fluid mechanics, and materials/structures, plus three design courses. Students can pursue Aerospace Engineering, Mechanical Engineering, or both tracks simultaneously.

Operations Research and Financial Engineering has the most elective-rich structure: after four core courses (ORF 245, 307, 309, 335), students choose 10-11 departmental electives with at least four from ORFE and no more than three from any single outside department. The two-term senior thesis (ORF 478) is credited 2× in spring.

Certificate Programs for BSE Students

One of Princeton’s most powerful academic features is its system of certificate programs — the university’s equivalent of minors. BSE students can pursue over 15 certificates alongside their engineering major, allowing them to develop expertise in complementary fields without extending their time to degree.

The most popular certificates among engineering students include:

• Applications of Computing: For students in non-COS departments who want to formalize their computational skills.
• Applied and Computational Mathematics: Deepens mathematical foundations relevant to modeling and simulation.
• Finance: Particularly popular among ORFE and ECE students, this certificate provides rigorous training in financial theory and practice.
• Statistics and Machine Learning: Increasingly sought-after, this certificate combines theoretical statistics with practical ML applications.
• Robotics and Intelligent Systems: Integrates coursework from MAE, ECE, and COS for students interested in autonomous systems.
• Sustainable Energy: Combines engineering with policy and environmental science for students focused on the energy transition.
• Engineering Biology: Bridges engineering methods with biological research, ideal for CBE students interested in biotech.

Additional options include Architecture and Engineering, Engineering Physics, Geological Engineering, Materials Science and Engineering, Optimization and Quantitative Decision Science, Technology and Society, Environmental Studies, Language and Culture, and Teacher Preparation. Students typically begin certificate coursework in sophomore year and should plan their schedules carefully to ensure all requirements are met by graduation.

Advising and Academic Support Resources

Princeton provides a multi-layered advising system designed to support BSE students from their first week on campus through graduation. Understanding these resources early can make a significant difference in academic planning and personal well-being.

First-Year Faculty Advisers are faculty members from one of the six engineering departments who also serve as fellows of the student’s residential college. They are matched based on student interests when possible, and required meetings occur at the start of fall term and during course selection for spring. After spring break, students transition to a departmental adviser in their chosen major.

Engineering Interactors are junior and senior BSE students paired with each faculty adviser. These peer mentors provide invaluable perspective on the engineering experience — from managing course loads and choosing electives to navigating research opportunities and extracurricular activities. They organize informal gatherings (pizza nights, ice cream socials) that help first-years build community within engineering.

The McGraw Center for Teaching and Learning offers review sessions, study halls, and group tutoring for challenging courses. Individual tutoring is available through residential college offices, and the Writing Center provides support for papers across all disciplines. Faculty office hours are described as “crucial” in the handbook — Princeton’s small class sizes and accessible professors are a defining feature of the experience. Note that outside tutoring is not allowed under university policy.

Key administrative contacts include Dean Peter Bogucki (SEAS Associate Dean for Undergraduate Affairs, reachable at BSEprogram@princeton.edu) and Traci Miller in the Undergraduate Affairs Office. Each department also has a Director of Undergraduate Studies and subject-specific placement officers for Chemistry, Computer Science, Mathematics, and Physics.

Study Abroad and Summer Opportunities

Princeton actively encourages BSE students to pursue international experiences. Study abroad is available in all six engineering disciplines, with Princeton maintaining exchanges with top engineering programs around the world. The typical timing varies by department: most students go during spring of junior year, while CBE students often go in sophomore spring and ECE students in junior fall.

Eligibility requires a minimum 3.0 GPA in the academic year prior to departure, and early planning is essential — students should begin exploring options during the spring of their first year. Information sessions are offered each semester, and Dr. Gisella Gisolo in the Study Abroad Program office serves as the primary resource for engineering students.

Summer opportunities are equally important to the Princeton BSE experience. Students can pursue research (including NSF Research Experiences for Undergraduates), industry internships (with companies increasingly interested after sophomore and junior years), or pre-approved courses at other institutions (maximum of four over the undergraduate career). The Center for Career Development, led by Associate Director Pamela Cohen for engineering students, offers comprehensive support including the Science and Technology Job Fair each October and the HandShake platform for internship and job searches.

Princeton recommends limiting campus employment to 10 hours per week during the academic year to protect academic performance. Summer course pre-approval must be obtained by Dean’s Date of the spring term.

Career Outcomes and Professional Licensure

Princeton BSE graduates pursue an extraordinarily diverse range of careers, reflecting the program’s emphasis on both technical depth and liberal arts breadth. Approximately 20% of graduates continue to PhD programs in engineering research, contributing to cutting-edge advances in their fields.

Beyond graduate school, Princeton engineers enter engineering practice at major companies, pursue careers in finance and consulting (leveraging their quantitative training), launch startups, attend medical school or law school, enter military service, or pursue careers in the arts including theater, music, and filmmaking. This diversity of outcomes is a direct reflection of the BSE program’s insistence on broad education alongside technical training.

For students interested in professional engineering licensure (P.E.), the path begins with an ABET-accredited degree. Princeton’s ABET-accredited programs include Civil Engineering, Chemical Engineering, Electrical Engineering, Aerospace Engineering, and Mechanical Engineering. The licensure process requires passing the Fundamentals of Engineering (FE) exam, accumulating supervised work experience, and passing the Professional Engineering (PE) exam. This credential is particularly important for CEE graduates who plan to practice structural or environmental engineering.

Princeton’s Center for Career Development provides comprehensive support including the Health Professions Advising Office for pre-med students, academic-athletic advising (Dean Alec Dun), and the International Internship Program for global career exploration.

Admission Requirements and Advanced Placement

Princeton’s BSE admission is highly competitive, drawing from the same applicant pool as the A.B. (Bachelor of Arts) program. Students indicate their preference for BSE or A.B. on their application, and the engineering school evaluates candidates based on academic achievement, standardized test scores, extracurricular engagement, and demonstrated interest in engineering and technical problem-solving.

Advanced Placement (AP) credit plays a significant role in shaping the first-year experience. Princeton awards a maximum of two terms of AP credit in any single subject. Important changes affect recent cohorts: students with 2020 or later Chemistry or Physics AP exams must take departmental placement tests regardless of their AP scores. College-level courses in chemistry or physics from other institutions also require placement tests. Math placement beyond BC Calculus requires approval from the Math Placement Officer.

Advanced Standing (early graduation) is possible for exceptionally prepared students. Full advanced standing (three-year graduation) requires eight units of AP credit including two in physics, placement out of Math 103-104, and one in chemistry. One-semester advanced standing requires four units including two in physics, one in math, and one in chemistry. Students must begin sophomore-level coursework immediately, and taking introductory-level courses (Physics 103, 105, EGR 151, or ISC) forfeits AP credit in physics and Advanced Standing eligibility.

Princeton’s seven residential colleges — Butler, Forbes, Mathey, New College West, Rockefeller, Whitman, and Yeh — provide the living-learning communities where first-year BSE students build friendships across engineering and the liberal arts. Each college has its own assistant dean, peer academic advisers, and social programming that complement the engineering-specific advising system.

The Engineering Quadrangle (E-Quad), built in 1962, serves as the central hub for most engineering activity, housing CBE, CEE, ECE, MAE, the Keller Center, and the Dean’s offices across its eight wings. The dedicated Computer Science Building (1989), Friend Center for Engineering Education (2001), Sherrerd Hall (2008, home to ORFE), and the Andlinger Center for Energy and the Environment (2015) round out the engineering campus.
