How to Apply to Mathematics at Rensselaer Polytechnic Institute: A B.S. with Four Concentrations in Mathematics, Applied Mathematics, Computation and Operations Research, Choosing the Major at Application, for Domestic, International (Including Chinese) and Transfer Applicants

At Rensselaer Polytechnic Institute (RPI), undergraduate mathematics is offered by the mathematics department and leads to a B.S. in Mathematics. Here is what you need to know, based on the department’s, the Office of Undergraduate Admissions’ and the Office of Financial Aid’s websites, organised for US domestic applicants, international applicants and applicants from China, followed by transfer students. Computer science is not covered here; this site has a separate article on it, and engineering, data science and other majors are not covered either.

1. Degrees and areas

• Degree: the department offers a Bachelor of Science in Mathematics, with four capstones that help students build a programme reflecting their interests and career objectives. The department lists programme outcomes including mathematical modeling, writing proofs, self-learning new concepts, and specialised knowledge in one or more of analysis and algebra, mathematics of computation, applied mathematics, or operations research.
• Four capstones: (1) Mathematics – rigorous proofs in mathematical analysis and linear algebra, with room for abstract algebra, geometry and number theory; (2) Applied Mathematics – modeling of observed phenomena and methods of analyzing the resulting problems; (3) Mathematics of Computation – the development, analysis and application of numerical methods, with flexibility for computer science and application fields; (4) Mathematics of Operations Research – mathematical programming and data science, emphasising analytical models of discrete systems in management, engineering and the social sciences. Separate requirements are listed for students entering in fall 2022 through 2026; the course counts and credits are in the university catalog, which was not read for this article.
• Free electives and dual majors: the department says the curriculum has nine free electives, which provide an opportunity to pursue a dual major. Recommended dual majors are Mathematics of Computation and Computer Science, Mathematics of Operations Research and Computer Science, Mathematics and Physics, Mathematics and Chemical Engineering, Mathematics and Psychology, and Mathematics and Communication. Under university rules, a student who fulfils all requirements of two curricula receives one diploma noting both majors; the student must designate a first-named and second-named major in writing at least one semester before graduation, with department approval, and each department assigns an adviser. The admissions FAQ says students typically begin with only one major and should speak with their adviser about adding a dual degree or minor after the first semester.
• Bachelor’s-plus-master’s and bachelor’s-plus-Ph.D. routes: the department says that by applying for an accelerated master’s programme students can start master’s courses in their junior or senior year and continue undergraduate financial aid through the ninth and tenth semesters, while skipping graduate admission tests and application fees. In the B.S. + Ph.D. accelerated programme, School of Science majors who have been at Rensselaer for at least a year with a GPA of 3.5 or higher are invited to apply in the summer before their second year, and the page says a Ph.D. can be earned seven years after starting college.
• The RPI Experience: the university’s academic and experiential learning pathway (formerly The Arch), with an Exploration Semester and a Discovery Semester, a required career development course and a required experiential learning experience; the department page mentions it.

2. How admission to the major works: choose the major at application

• At application: the admissions FAQ says there is flexibility to change majors once you are here, but applicants are encouraged to be as specific as they can when choosing a major (or school) on the application. Options are a specific major, or undeclared within a specific school (for example undeclared engineering). Architecture and Games and Simulation Arts and Sciences applicants are advised to apply directly to those programmes, and the medical accelerated programme requires a direct application. Whether mathematics is reviewed separately, has limited places or a separate admission line is not stated in the pages read; please ask the admissions office.
• Changing the major after applying: use the “Change in Major Form” in the application portal; staff confirm by email.
• After entry: the department says every student who declares mathematics is assigned a faculty advisor who helps tailor the programme over four years; students consult them at registration each term. The page lists advisors by class year and by surname. Conditions for moving into mathematics from another major are not stated in the pages read.
• School: the mathematics pages read do not say which school the department belongs to, though the B.S. + Ph.D. page addresses School of Science majors; any separate school-level admission line is not stated in the pages read.

3. Prerequisites and placement

• High school coursework: the admissions office says the applicants best suited for RPI will have completed four years of mathematics through pre-calculus (calculus recommended); three years of science including chemistry and lab-based physics (physical science and conceptual physics do not count; biology is recommended and required for bio-focused majors); four years of English; and three years of social studies and/or history.
• AP mathematics credit (for students entering from fall 2024): AB score of 4 or 5 – four credits for Calculus I, and register for Calculus II if the major requires it; BC score of 4 or 5 – eight credits for Calculus I and II, then MATH-2010 or MATH-2400 depending on the major. AP Statistics 4 or 5 earns MGMT-2100 Statistical Methods (four credits), which non-management majors cannot count toward the math/science requirement. Overall: first-year students from fall 2024 may transfer at most 32 credit hours; AP and similar credit requests must be completed by the end of the first year; official AP scores need to go to the Registrar only if you are admitted and enrol.
• IB credit: a 6 or 7 on the higher-level mathematics exam earns MATH-1010 Calculus I (four credits); standard-level exams are not considered.
• Honors: the pages read do not describe an honors mathematics sequence or how to enter it; the department page lists Pi Mu Epsilon, the national mathematics honor society.
• Math competitions: the department lists the Putnam Competition (in 2014 an RPI undergraduate team placed third out of more than 430 teams), the Mathematical and Interdisciplinary Contest in Modeling (MCM/ICM) and a weekly Math Club. How competitions are viewed in admission is not stated in the pages read.

4. Deadlines and application materials

• Rounds and deadlines (fall 2027): the admissions page lists Early Decision I (binding) 1 November, notification 12 December; Early Action (non-binding) 1 December, 30 January; Early Decision II (binding) 6 January, 16 January; Regular Decision 15 January, 6 March. FAFSA and CSS Profile priority dates: ED I 15 November, EA 15 December, ED II 8 January, RD 31 January. Another page gives the ED II priority date as 9 January, so the two pages disagree. There is no rolling admission for first-year fall applicants.
• How to apply and fee: the Common App or the RPI application; the fee is $70 (non-refundable), with no fee for applications submitted by 1 December; a waiver is available if total family income is $70,000 or less and the fee is a hardship.
• Materials: an official high school transcript from your school (including dual-enrolment, college or self-study courses not on it); first quarter/trimester grades for ED and EA applicants; a mid-year report for Regular Decision applicants (by mid-to-late February at the latest); a letter of recommendation from a counselor or teacher, “preferably a math or science teacher who knows you well”; the general essay satisfies the essay requirement (some programmes such as architecture have their own). Supplemental materials may arrive in the weeks after the deadline; the office aims for a complete file within two weeks.
• Interview: RPI does not conduct interviews. U.S. high school students may submit a 60–90 second GLIMPSE video (deadlines ED I 15 November, EA 15 December, ED II 5 January, RD 29 January); international applicants may take an optional InitialView interview.
• Testing: test optional for fall 2027 applicants, and the page says RPI will remain test-optional through the fall 2030 application cycle. SAT is superscored, ACT uses only the highest composite; scores may be self-reported and official scores are required on enrolment (SAT code 2757, ACT code 2866). Tests must be taken by the December test date.

5. US domestic applicants

• Costs (2026-27 estimate): the cost of attendance page lists undergraduate tuition $66,300, fees $1,676, food and housing $18,870, books and supplies $1,410, personal expenses $1,280 and transportation $540, a total of $90,076. All students need a laptop, about $2,000 if bought from Rensselaer (added to the cost estimate for aid only if the aid office knows of the purchase); food and housing for students living with relatives is estimated at $10,820. The page lists a single tuition figure and does not distinguish in-state from out-of-state students. The rates for fall 2027 entry are not stated in the pages read.
• Aid: to be considered for need-based aid, submit both the FAFSA (Troy campus code 002803) and the CSS Profile (code 2757); the CSS Profile is filed once, the FAFSA each year. Applicants not seeking need-based aid do not need to file.
• Merit awards: the scholarships page lists the Rensselaer Medal Award (for promising secondary school juniors who have distinguished themselves in mathematics and science, first presented in 1916), the Leadership Award, the Garnet Baltimore Award, the Recognition Award (holistic review) and the 2024 Bicentennial Award; eligibility and amounts are in the academic catalog, which was not read. A student eligible for several receives the highest single award.
• In-state priority or guaranteed admission: not stated in the pages read.

6. International applicants

• Who is international: any student who is not a U.S. citizen or permanent resident, wherever they live or attend school; RPI accepts international students into all programmes except the Physician-Scientist (B.S./M.D.) programme.
• English requirement: all non-native speakers must submit one of: TOEFL iBT at least 88 (or 4.5 on the new 6.0 scale; Home Edition accepted); IELTS overall at least 6.5; Duolingo at least 115; PTE at least 59. Official scores must come from the testing agency, with no self-reporting (TOEFL code 2757), and the exam should be taken by December of senior year. Exemptions include SAT EBRW 640+, ACT English 22+, IB English A HL 6+, IGCSE or A/AS-Level English grade B or higher, Cambridge English B2/C1 185+, three or more years of U.S. secondary education (by form), or a diploma from a listed English-medium country or territory (China is not on the list).
• Materials: official transcripts of all secondary schools with English translations, and the International Student Financial Statement (ISFS), uploaded to the portal after the enrollment deposit, with documentation of at least one year’s liquid funds, approximately $80,000. An InitialView, Duolingo or Vericant interview is optional.
• Scholarships: limited merit scholarships are available for undergraduate international students, up to $20,000 per year; all non-U.S. citizens/permanent residents must be prepared to assume the full cost of attendance for the duration of their studies.

7. Applicants from China

• Gaokao: whether it is considered, and how, is not published in the pages read; please contact the admissions office (admissions@rpi.edu).
• Transcripts and school-leaving materials: the admissions office says applicants from China may submit junior high school transcripts (grades 7–9) along with their A-level coursework for admission consideration. Other China-specific requirements are not stated in the pages read; the general international requirement is official transcripts with English translations.
• International curricula: students taking AP, IB or A-Level can use the credit rules in section 3; China is not on the English-medium exemption list, so an English exam is needed (section 6).

8. Costs, scholarships and outcomes

• Costs: see section 5.
• Department awards: the awards page lists the Max Hirsch Prize (for a senior in the Department of Mathematical Sciences with outstanding academic work and promise of career success in mathematical sciences) and the Bill and Nancy Siegmann Applied Mathematical Modeling Prize (for an undergraduate whose work best exemplifies elegance in problem formulation, solution and interpretation). Math-specific entrance scholarships and award amounts are not stated in the pages read.
• Undergraduate research: the School of Science research page says undergraduates are encouraged to take part in research from the moment they arrive and can join the Undergraduate Research Program (URP), working with faculty for academic credit or as paid assistants; URP assistantships are part-time in the academic year and full-time in the Summer Undergraduate Research Program.
• Outcomes: the mathematics pages read print no career or employment data; see the department and the university’s career center.

9. Transfer students

• Who counts as a transfer: any student with 12 or more transferable college credits completed after high school; transfer students can apply to all programmes except the accelerated medical programme, using the Transfer Common App or the RPI Transfer Application. Applications are reviewed on a rolling basis.
• Deadlines: fall entry 1 June, spring entry 1 November; Architecture, Games and Simulation Arts and Sciences, and Music applicants must apply for fall. The page shows no year, so check. Materials: the application, fee, official transcripts from all colleges, one letter of recommendation (instructor or academic counselor), and the final high school transcript for those with fewer than four semesters of college work.
• Prerequisites and GPA: you must complete at least a pre-calculus level mathematics course before enrolling, and most majors require a completed physics course. RPI generally looks for a GPA of 3.0 or higher, but the page says this is a guide and not a hard cutoff, and the courses should suit the intended major; applicants must be in good academic standing. Math-major-specific transfer requirements are not stated in the pages read.
• Credit transfer: credit is transferred only for courses with a grade of C- or better; transfer students can expect full credit for courses of comparable depth. After acceptance, course descriptions go to faculty and the evaluation is available before the enrollment deposit is due. To earn an RPI undergraduate degree, a student must register full-time for at least four semesters and complete at least 64 credits at RPI.
• 2:2 programmes: graduates with an A.S. degree from a participating two-year or community college may transfer with full junior status if accepted; several listed colleges include science (SCI) programmes.
• International transfer students: official transcripts of all college work with English translations, the ISFS (also about $80,000 in liquid funds) and English results; for transfer applicants the IELTS expectation is 7.0 overall (TOEFL 88/4.5, Duolingo 115 and PTE 59 are the same as for first-year applicants).
