As a participant, you’ll gain a high-level understanding of data science and build a solid foundation you can use as a stepping stone to programming and modeling courses.

Emeritus and UC Berkeley Extension

UC Berkeley Extension is collaborating with online education provider Emeritus to offer a portfolio of high-impact online courses. These courses leverage UC Berkeley’s thought leadership in technical practice developed over years of research, teaching, and practice. By collaborating with Emeritus, we are able to broaden access beyond our on-campus offerings in a collaborative and engaging format that stays true to the quality of UC Berkeley. Emeritus’ approach to learning is formulated on a cohort-based design to maximize peer-to-peer sharing and includes live teaching with world-class faculty and hands-on project-based learning. In the last year, more than 30,000 students from over 120 countries have benefited professionally from Emeritus.
