Apply to Engineering, not to a major
Columbia says students apply to either Columbia College or Columbia Engineering. The pages read describe no separate application to Operations Research.

Columbia Operations Research: a mathematical IEOR major within Engineering
Columbia admits students to Columbia College or to Columbia Engineering, and Operations Research is one of five majors offered by Engineering's Department of Industrial Engineering and Operations Research. The Academic Catalog describes common requirements in mathematics, programming and operations research methods, then a specialised major with a strong focus on mathematics applications. For an A-level or IB applicant, the questions are how this major differs from its IEOR siblings, where it sits in the admission model and what Columbia asks, including the SAT or ACT from August 2027. This guide claims no separate admission to Operations Research.

What Columbia says about Columbia Operations Research
Taken from Columbia Undergraduate Admissions' Academics, Testing and International Applicants pages and the Columbia Engineering Academic Catalog's Industrial Engineering and Operations Research undergraduate programs page, read on 31 October 2026. The pages carry no entry-year label, so for a 2028-entry application every statement below is evidence for the previous cycle and may change; check Columbia's pages for the 2028-entry details.
Five IEOR majors
Students in all five complete common requirements in mathematics, computer programming and operations research methods.
A mathematics-heavy major
The catalogue describes a strong focus on mathematics applications, preparing students for advanced study or work as operations research analysts.
Specialisations for the Classes of 2027 and 2028
Analytics, Engineering Management Systems and Financial Engineering are listed as specialisations for those class years.
SAT or ACT from August 2027
Columbia says it will require ACT or SAT results from first-year and transfer applicants starting in August 2027.

The major
What the Academic Catalog says Operations Research is
The Academic Catalog describes the IEOR department as applying mathematical models to improve decision-making in complex environments, with five majors that share foundations in mathematics, computer programming and operations research methods. The Operations Research major, offered to all class years, has a strong focus on mathematics applications and prepares students for advanced study or work as operations research analysts in professional services, financial services and large technology organizations. The catalogue lists three specialised variants, Analytics, Engineering Management Systems and Financial Engineering, for the Classes of 2027 and 2028. This guide did not read the full requirement lists, so it names no courses.
Is it the right major?
Operations Research or a nearby route
Columbia describes these as separate majors, so the choice is made after admission. Avandy's comparison is general.
Operations Research fits if
you want a mathematics-led route into optimisation, analytics and decision-making.
A specialised variant fits if
you already know you want analytics, engineering management or financial engineering.
Financial Economics in the College fits if
you want finance through economics rather than engineering. Avandy's Columbia Financial Economics guide covers it.
Admission and testing
SAT or ACT from August 2027, and your curriculum
Columbia says that starting in August 2027, Columbia College and Columbia Engineering will require first-year and transfer applicants to submit ACT or SAT results. It accepts all secondary curricula, including the IB and Cambridge A Levels, and A Level and IB results must be submitted if they are required to complete and graduate from secondary school. This guide states no score.
A decision framework
Three questions before you commit
This is Avandy's own framework, not Columbia's.
Do you enjoy applied mathematics?
The catalogue's emphasis is mathematics applications.
Do you want to apply to Engineering?
The major sits in Columbia Engineering; the College is a different application.
Can you plan the SAT or ACT?
Columbia says one is required from August 2027.
Planning for 2028 entry
Planning for 2028 entry: what carries over and what is awaiting publication
Columbia's pages carry no entry-year label, so nothing on them is confirmed for 2028 entry. Use them to understand the structure of the application, then check Columbia's own pages for the 2028-entry details.
The requirements and descriptions on the pages read on 31 October 2026, which carry no entry-year label
These are the best guide to what to prepare. Columbia has not confirmed them for 2028 entry.
Deadlines, fees, financial aid and any department prerequisites not quoted here: not stated
This guide has not read them. Check Columbia for the values that apply to your application year.
What to do now
Read the IEOR undergraduate programs page and plan the SAT or ACT.
Support
Independent support with planning your own application
Avandy provides independent academic and admissions support. It is not affiliated with Columbia Engineering or any of its colleges or departments. Preparation sits within the Avandy Trinity Advisory Model: a Strategic Admissions Consultant, a PhD-level Academic Mentor and a Subject-specific Tutor, working to the actual requirements of each course. Support here is limited to understanding the requirements and planning the applicant's own work; Avandy does not write or edit essays, does not submit any materials and has no partnership with Columbia Engineering. No outcome is promised.
Questions
Questions applicants ask
Can I apply directly to Columbia Operations Research?
The pages read describe applying to Columbia College or Columbia Engineering, not to a major.
How many majors does IEOR offer?
Five. Students in all five complete common requirements in mathematics, programming and operations research methods.
Which specialisations are listed?
Analytics, Engineering Management Systems and Financial Engineering for the Classes of 2027 and 2028.
Do I need the SAT or ACT?
Columbia says it will require them starting in August 2027.
Does Columbia accept A Levels and the IB?
Yes. Columbia says it accepts all secondary curricula and reviews applications in the context of the curriculum.
Are these the rules for 2028 entry?
No. They are Columbia's wording with no entry-year label. Check Columbia's pages again when Columbia publishes its 2028-entry requirements.
