What is COSMOS?
The California State Summer School for Mathematics & Science
COSMOS is a 4-week, residential summer program for high school scholars with demonstrated interest and achievement in math and science. COSMOS provides students with an unparalleled opportunity to work side-by-side with outstanding researchers and UC Santa Cruz faculty, covering topics that extend beyond the typical high school curriculum.

Clusters
Explore our COSMOS “clusters” or courses provided here at UCSC by clicking the images below! Each cluster is comprised of two science, math and/or engineering courses and one transferable skills course. (if an “*” follows the cluster title, that cluster has a prerequisite)
