- 2 electives
- 1 data science course (taken as the third or final course)
Selecting courses. Multiple course options are available during fall, spring, and summer terms. Offerings vary by term. Explore current options in the DCE Course Search & Registration platform.
Recommended Prerequisite Knowledge
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 100 before beginning this certificate.
The data science certificate will be difficult without knowledge of Python. If you do not have a background in programming, you should consider first taking CSCI 7. You may wish to consider our Programming Certificate.
