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
