California Institute of Integral Studies (CIIS) is a private institution of higher education founded in 1968 and based in San Francisco, California. It currently operates in two locations just south of the Civic Center district. CIIS has a total of 1,400 students and 72 core faculty members.
The Institute consists of three schools: the School of Professional Psychology & Health, the School of Consciousness and Transformation (mainly humanities subjects), and the School of Undergraduate Studies. Many courses combine mainstream academic curriculum with a spiritual orientation, including influences from a broad spectrum of mystical or esoteric traditions. Although the Institute has no official spiritual path, some of its historical roots lie among followers of the Bengali sage Sri Aurobindo.
In 2003, the Doctor of Psychology (PsyD) program in Clinical Psychology received accreditation from the American Psychological Association (APA). This accreditation was revoked in 2011. CIIS's appeal of the decision was denied in 2012.
