The first California History-Social Science Project (CHSSP) activity began in 1989 at UCLA, shortly after the California Subject Matter Projects (CSMP) was created in 1988. Other campus sites arose beginning in 1991. The number of sites grew steadily until the network hit its peak in 2001, when 17 sites on UC and CSU campuses made up the CHSSP network. Currently, the CHSSP has sites at:
- CSU Chico
- UC Davis
- UC Berkeley
- CSU Fresno
- UCLA
- CSU Long Beach & Dominguez Hills
- UC Irvine
Each site’s leadership team is generally composed of at least one site director (usually a former K12 teacher or historian) and one or more faculty advisors.
