Data Science, B.S.

The Saint Louis University Bachelor of Science in Data Science is an interdisciplinary program supported by the Department of Computer Science and the Department of Mathematics and Statistics. The curriculum is modeled upon guidelines for undergraduate programs in data science as endorsed by the American Statistical Association's Board of Directors. Classes are small and are taught by enthusiastic instructors.

Curriculum Overview

The B.S. in data science is among the most rigorous degrees offered at SLU. This program combines carefully selected computer science, statistics and mathematics courses with four semesters of practica and capstone experiences. The result is an education that is rooted in the fundamentals, but also provides hands-on experience with cleaning, visualizing, analyzing and reporting on data. Students choose electives within the major to specialize more in the computer science or statistical aspects of data science. 

Fieldwork and Research Opportunities

Faculty in the data science program do research in machine learning, natural language processing, time series, topological data analysis, and in other areas of statistics, computer science and mathematics.

There are multiple research, internship and consulting opportunities for students in the data science program. Past students have done cross-disciplinary work with ArchCity Defenders, the Department of Sociology, the Department of Languages, Literature and Cultures, the Department of English, the Medical School Liver Center, while others have done work in data science itself doing research with faculty within the Departments of Mathematics and Statistics, the Department of Computer Science and the Lincoln Lab at MIT, among others.

The SLU Data Science Club provides students with an opportunity to practice their predictive modeling in competitions. Some competitions are hosted locally by SLU solely for students at SLU, while others pit SLU students against students and professionals from across the world.


The McKinsey Report estimated that the United States would face a shortfall of between 140-190 thousand people with deep analytical skills, while also needing 1.5 million managers and analysts with the know-how to make decisions based on the analysis of big data.

The Harvard Business Review calls data scientist "the sexiest job of the 21st century,” and each year from 2016-2018, Glassdoor has ranked data scientist as the No. 1 overall job in the USA in terms of the number of job openings, earning potential and career opportunities rating.  Data is being produced in many places, and companies need employees who can analyze the data and communicate about the results. Students with a B.S. in data science will be well positioned to work in technology, government, research and consulting fields, among others. 

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 in the form of grants and loans, some of which require repayment.

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

Program Notes

Data Structures (CSCI 2100) and Foundation of Statistics (STAT 3850) are the two crucial courses to the degree path. Data Structures (CSCI 2100) is a prerequisite for all further study in computer science for this major; some courses have additional prerequisites. Foundation of Statistics (STAT 3850) is a prerequisite for all further study in statistics; some courses may have additional prerequisites. The courses required for Data Structures (CSCI 2100) are: Introduction to Computer Science: Taming Big Data (CSCI 1070), Introduction to Object-Oriented Programming (CSCI 1300) and Discrete Mathematics (MATH 1660). The courses required for Foundation of Statistics (STAT 3850) are: Calculus I (MATH 1510) and Calculus II (MATH 1520).  Other potential roadblocks are: 

1. Data Science Practicum I (DATA 1800) must be completed by Spring one year before the student wishes to graduate. It is a prerequisite for Data Science Practicum II (DATA 2800), offered in Spring.
2. Linear Algebra for Engineers (MATH 3110) (recommended) and Calculus III (MATH 2530) (required) should be completed before Machine Learning (CSCI 4750) and Applied Regression (STAT 4870).
