Who Should Enroll: Prerequisites
Knowledge of statistics and basic programming is recommended for this certificate. If you do not have a strong background in statistics, start with an introductory statistics course, such as STAT E-100 before beginning this certificate.
The data science certificate will be difficult for students with no knowledge of Python. If you do not have a background in programming, you should consider first taking CSCI E-7. You may wish to consider our Programming Certificate.

Build a Stackable Credential Pathway
Stackable credential pathways allow you to earn multiple credentials by completing courses that meet overlapping requirements. In the short term, you can earn a micro or graduate certificate. Once completed, those courses may count toward a master’s degree.
You can:
- Stack the Data Modeling and Ethics Microcertificate into the Data Science Graduate Certificate.
- Stack the Data Science Graduate Certificate into a Data Science Master’s Degree.
Stackable pathways offer an efficient, cost-effective way to earn short-term credentials to help fill immediate skill gaps and acquire specialized knowledge while building a foundation for long-term success that showcases your expertise in the field.

FAQs
Will the graduate certificate in data science help me advance in my career?
Pursuing this online graduate certificate will give you the latest skills in data analysis, innovation, and research. Students who have earned the Data Science Graduate Certificate have secured roles such as consultant, data analyst, data engineer, and data scientist at top companies, including Apple, Amazon, Bank of America, Cognizant, Google, Hewlett Packard, Microsoft, Oracle, and Verizon.
What is the difference between a data science certificate and a data science master’s degree?
The Data Science Graduate Certificate consists of four courses (16 credits) and provides foundational expertise in machine learning, predictive modeling, and data analytics. This program equips students with essential skills in handling, analyzing, and interpreting data to drive decision-making. For those looking to deepen their knowledge, the Data Science Master’s Degree offers an advanced curriculum, covering data engineering, deep learning, LLM models, big data analytics, and the ethical and legal dimensions of data applications. In addition to coursework, the Data Science Master’s Degree program emphasizes data visualization, hands-on problem-solving through a team-based capstone project, and collaborative proposal development during an immersive on-campus experience, where students engage in research-driven discussions and apply their skills to real-world challenges. With a flexible format—11 online courses and 1 required on-campus session—students can balance their education with professional commitments.
How long will it take to complete the data science certificate?
This online graduate certificate program is designed with flexibility in mind. You are required to complete four courses (16 credits), but you can spread these courses out, up to three years, depending on your schedule. Most students complete the certificate within 18–24 months.
Does the program cover artificial intelligence?
Yes, this graduate certificate program includes elective course options in artificial intelligence. If you are looking to specialize even further, you could also explore the Artificial Intelligence Graduate Certificate.
What is the typical weekly time commitment for each course?
Each course usually requires a commitment of 8 to 12 hours per week. This time includes the online course, assignments, and participating in hands-on projects.
How do I get started on the certificate?
To get started on your Data Science Graduate Certificate, you simply register for your first course. We offer courses during the fall, spring, and summer semesters. There is no application.
