Mathematics, B.S.

Saint Louis University’s mathematics program combines the features of both small and large schools to create a compelling educational experience.

Students can expect a student-friendly environment, with math courses for majors being small in size and taught by regular faculty. Faculty get to know students and provide individual attention. Students are recruited for participation in math contests and other opportunities, including part-time positions as graders, tutors and learning assistants. Like a large school’s program, math at SLU also has enough breadth to let students tailor their upper-division math courses to their interests and goals.

Program Highlights

  • Students interested in pure mathematics can choose theoretical courses that provide solid preparation for graduate school. Since SLU has a graduate program in mathematics, exceptional undergraduate students have the opportunity to take graduate courses in mathematics.
  • Students interested in applied mathematics (or science and engineering students interested in a second major in mathematics) can focus on a wide selection of applied courses. 
  • Students interested in statistics can select various statistics and probability theory courses.
  • Students interested in secondary school teaching can select courses that fulfill the requirements of the major and a teaching certificate at the same time.

Curriculum Overview

All students majoring in mathematics start with a core of five required courses, including calculus and linear algebra. The B.S. in Mathematics is designed to provide a strong grounding in mathematics for students considering graduate school in mathematics or a closely allied field.

For the B.S. degree, the student builds on the fundamental core of required courses with a selection of nine upper-division courses, chosen to include pure mathematics courses in real analysis and algebra, an upper-level statistics course, two upper-division sequences including one in pure mathematics, and electives to complete the required nine upper-division courses. Students must also take at least one course in computer programming and one in another discipline with a strong mathematical or computational component.

The requirements for the B.S. in Mathematics follow the recommendations of the Mathematics Association of America for degree programs in mathematics that prepare students for graduate work.

Fieldwork and Research Opportunities

The SLU Mathematics and Computer Science Club allows students interested in mathematics and computers to explore relevant topics outside of the classroom. The club holds weekly meetings that bring students and faculty together for various activities, including mathematical puzzles, integration bees, game beta testing and career-focused presentations by industry experts.


Mathematics emphasizes careful reasoning, along with the analysis and solution of problems. A major or minor in mathematics at Saint Louis University will appeal to students who like to develop their problem-solving and analytical thinking skills. For this reason, mathematics is also an appropriate major for students planning careers in law or medicine.

Graduates in mathematics and statistics are versatile. They enter jobs in business, industry, medicine, government and education. Mathematicians, statisticians, data scientists, actuaries, analysts and consultants are in high demand and lead rewarding and well-compensated careers.

Many of our graduates pursue advanced degrees in mathematics, statistics or other fields. Students with mathematics and statistics degrees are attractive to professional graduate schools in law, medicine, and business because these graduate programs value analytical skills and the ability to work in a problem-solving environment.

Some of the industry and government employers where our graduates have found success include:

  • Allstate
  • Ameren
  • Boeing
  • Booz Allen Hamilton Consulting
  • Boston Scientific
  • Cofactor Genomics
  • Georgia-Pacific
  • Kemper Insurance
  • Mercer
  • MetLife
  • Milliman
  • National Geospatial-Intelligence Agency
  • National Security Agency
  • NISA Investment Advisors
  • Varsity Tutors

Admission Requirements

Begin Your Application

Saint Louis University also accepts the Common Application.


All applications are thoroughly reviewed with the highest degree of individual care and consideration to all credentials that are submitted. Solid academic performance in college preparatory coursework is a primary concern in reviewing a freshman applicant’s file.

To be considered for admission to any Saint Louis University undergraduate program, applicants must be graduating from an accredited high school, have an acceptable HiSET exam score or take the General Education Development (GED) test. 


Applicants must be a graduate of an accredited high school or have an acceptable score on the GED.

Students who have attempted fewer than 24 semester credits (or 30 quarter credits) of college credit must follow the above freshmen admission requirements. Students who have completed 24 or more semester credits (or 30 quarter credits) of college credit must submit transcripts from all previously attended college(s).

In reviewing a transfer applicant’s file, the Office of Admission holistically examines the student’s academic performance in college-level coursework as an indicator of the student’s ability to meet the academic rigors of Saint Louis University. Where applicable, transfer students will be evaluated on any courses outlined in the continuation standards of their preferred major.

International Applicants

All admission policies and requirements for domestic students apply to international students along with the following:

  • Demonstrate English Language Proficiency
  • Proof of financial support must include:
    • A letter of financial support from the person(s) or sponsoring agency funding the time at Saint Louis University
    • A letter from the sponsor's bank verifying that the funds are available and will be so for the duration of study at the University
  • Academic records, in English translation, of students who have undertaken postsecondary studies outside the United States must include the courses taken and/or lectures attended, practical laboratory work, the maximum and minimum grades attainable, the grades earned or the results of all end-of-term examinations, and any honors or degrees received. WES and ECE transcripts are accepted.

Scholarships and Financial Aid

There are two principal ways to help finance a Saint Louis University education:

  • Scholarships: Scholarships are awarded based on academic achievement, service, leadership and financial need.
  • Financial Aid: Financial aid is provided through grants and loans, some of which require repayment.

Saint Louis University makes every effort to keep our education affordable. In fiscal year 2023, 99% of first-time freshmen and 92% of all students received financial aid and students received more than $459 million in aid University-wide.

For priority consideration for merit-based scholarships, apply for admission by December 1 and complete a Free Application for Federal Student Aid (FAFSA) by March 1.
