There is an urgent need to expand access, diversify participation, and support data science teaching across higher education institutions in the state of California. This sector will be fundamental to the health of the state’s economy, and a well-trained workforce will be a basis for jobs in Data Science, Machine Learning, Artificial Intelligence, and across the innovation ecosystem. The California Alliance for Data Science Education seeks to solve challenges in California Community Colleges (CCCs), California State Universities, and the University of California system in areas such as building shared infrastructure, smoothing community college transfer pipelines, and empowering leaders at partner campuses.
