The Online Post-Baccalaureate Certificate in Data Science at Tufts University is a 100% online program designed for students and professionals who want foundational preparation in data science. Students build knowledge in mathematics, programming, probability, statistics, and applied machine learning while preparing for continued graduate study or data-focused professional opportunities.

The program requires 20–24 credits and may be completed through full-time or part-time online study. Students typically complete the certificate in 12 to 28 months.

The program offers two pathways:

Certificate Track: A standalone credential for students seeking foundational preparation in data science.
Master’s Track: A pathway for students who intend to continue into the M.S. in Data Science at Tufts.

Who is this Program For?

The Online Post-Baccalaureate Certificate in Data Science is designed for applicants with at least a bachelor’s degree who want to build foundational data science knowledge through online study. No prior educational experience in data science is required.

This program may be a strong fit for applicants who want to:

Develop preparation in mathematics, programming, probability, statistics, and machine learning
Learn to organize, analyze, interpret, and communicate with data
Build skills relevant to data-focused professional responsibilities
Prepare for advanced study in data science
Pursue a pathway toward the M.S. in Data Science at Tufts

Applicants who already have sufficient quantitative and data science preparation for graduate-level coursework should explore the Online Certificate in Data Science.

What Will You Study?

Students complete six courses that provide foundational preparation for data science study and applications.

Foundational Coursework

Both tracks include four undergraduate-level courses in mathematics and programming. These courses build preparation in areas such as:

Linear algebra
Programming for data analysis
Data structures
Mathematical and logical problem-solving

Graduate Coursework

Students then complete two graduate-level courses focused on:

Probability theory
Fundamentals of applied machine learning

Students in the Master’s Track continue building preparation for graduate study in areas such as applied statistics, large-scale data analysis, and data infrastructure. Through this coursework, students build knowledge in:

Linear algebra, probability, and statistics
Programming with tools such as Python
Data structures and computational problem-solving

Supervised and unsupervised machine learning
Application of standard machine learning models to data sets
Communication of data-informed insights
