California State Summer School for Mathematics & Science (COSMOS)

innovation begins with education

Preparing the next generation of STEM leaders


COSMOS is limited to high-school students who either attend a California high school or are residents of California. 

All accepted students must show proof of vaccination and a negative COVID test 72 hours or less before arrival.

** COSMOS is planning for a fully residential and in-person 2023 program. In case directives from public health and university officials prevent the residential, in-person activities from happening, COSMOS will then update applicants with their options. These options may include being considered for a remote instruction version of COSMOS with appropriately reduced tuition or withdrawing their application. Some planned clusters may not be suitable for remote instruction, and COSMOS will, for such clusters, attempt to identify alternatives. All tuition payments by admitted students will be fully refunded if the program is canceled or if an admitted student does not accept a remote instruction alternative. It is reemphasized that COSMOS intends to be a residential program. **

COSMOS is an intensive four-week summer residential program for students who have demonstrated an aptitude for academic and professional careers in science, technology, engineering, and mathematics (STEM) subjects. Talented and motivated students completing grades 8-12 have the opportunity to work with renowned faculty, researchers, and scientists in state-of-the-art facilities while exploring advanced STEM topics far beyond the courses usually offered in California high schools. Through challenging curricula that are both hands-on and lab-intensive, COSMOS fosters its students’ interests, skills, and awareness of educational and career options in STEM fields.

Students apply to one of the four University of California’s COSMOS campuses — UC Davis, UC Irvine, UC San Diego, and UC Santa Cruz. While each campus employs the best practices in STEM education, the curriculum of each program builds on the unique teaching and research expertise of its faculty and host campus. Each campus can only accommodate about 160-200 participants. The selection is competitive. A typical COSMOS student has a GPA of 3.5 or above. In addition, students must have achieved academic excellence.
