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 three locations just south of the Civic Center district. CIIS has a total of 1,400 students and 69 core faculty members. The Institute consists of three schools: the School of Professional Psychology, 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. CIIS is an accredited member of the Western Association of Schools and Colleges (WASC). In 2003, the Doctor of Psychology (PsyD) program in Clinical Psychology earned the accreditation of the American Psychological Association (APA), although this program is currently on probation by the APA.
