Facilities

Its facilities include Level I ("Open dormitories without a secure perimeter") housing, Level II ("Open dormitories with secure perimeter fences and armed coverage") housing, and Level III ("Individual cells, fenced perimeters and armed coverage") housing.

CIW is located east of Downtown Los Angeles, and it takes about one hour to travel to the prison from Downtown LA.

History
The original California Institution for Women was dedicated in Tehachapi in 1932; however, after the 1952 Kern County earthquake, the female inmates were transferred to the just-opened CIW in Chino, and the Tehachapi facility was rebuilt as the male-only California Correctional Institution. CIW was originally called "California Institution for Women at Corona," but "Corona residents objected to the use of their city in the prison's name and it was changed March 1, 1962, to Frontera, a feminine derivative of the word frontier, symbolic for a new beginning." It housed the location of the death row for women in the state. CIW was the only women's prison in California until 1987, when the Northern California Women's Facility opened.

In the early years of CIW, convicted women wore Sunday dresses while walking and working at the campus-like setting until the 1980s when three towers were added with officers atop armed with shotguns.  Among other programs for inmates at CIW is "Voices from Within" in which inmates read books on tapes for "high school students in remedial classes," "college students with reading disabilities," and the blind.

In 2007, the state of California proposed building 45 new units for mentally ill inmates at CIW and 975 at the nearby California Institution for Men; local officials opposed such plans.

From 2006 to 2013 one woman at CIW committed suicide. From January 1, 2013 to July 2016 six women committed suicide at CIW, and there had been an increase in suicide attempts.
