California Institution for Men (CIM) is a male-only state prison located in the city of Chino, San Bernardino County, California. It is often colloquially referenced as "Chino". In turn, locals call the prison "Chino Men's" or just "Men's" to avoid confusion with the city itself. Facilities CIM is a facility located east of Los Angeles on arid farmland. Facilities include: "The largest Level I inmate population within the California prison system" ("Level I" referring to "open dormitories without a secure perimeter"). Three Reception Centers (RCs) which "provide short term housing to process, classify and evaluate incoming inmates." Reception Center Central for medium/maximum custody level inmates "receives intake from several southern California counties"; Reception Center East "houses [medium/maximum custody level] Reception Center inmates with sensitive needs, Mental Health inmate/patients requiring an Enhanced Out-Patient level of care and a 100 bed HIV/CID unit"; and Reception Center West is for "medium level custody inmates" who are "waiting processing/transfer to programming institutions." The counties served by Reception Center Central include Orange County, Riverside County, Santa Clarita County, San Diego County and San Bernardino County. It also serves prisoners transferred from the Pitchess Detention Center in Castaic, Los Angeles County. Population and staffing As of Fiscal Year 2006/2007, CIM had 2,327 staff and an annual budget of $232.2 million.

As of April 30, 2020, CIM was incarcerating people at 112.8% of its design capacity, with 3,357 occupants. History CIM opened in 1941 and "was the first major minimum security institution built and operated in the United States." It was the fourth state prison built in California (after San Quentin State Prison, Folsom State Prison, and the original California Institution for Women at Tehachapi). Since the California Correctional Institution replaced the original California Institution for Women at Tehachapi, CIM is now the third-oldest California state prison. In 1970, a commercial diver training program started at CIM. In following years, the program's graduates had much success in finding jobs after release from prison and a recidivism rate of only 12 percent. The program was "closed in 2003 due to budget constraints," but reopened in 2006. Inmate Kevin Cooper escaped from CIM in 1983.
