In the spring of 2014, the National Charter School Resource Center ("Resource Center"), the Colorado League of Charter Schools ("League"), the National Alliance for Public Charter Schools ("Alliance") and the California Charter Schools Association ("CCSA") worked to collect evidence about charter school facilities and facilities expenditures in the state of California. This report is based on survey, enrollment, and operating revenue data collected for the 2013-2014 school year. All results presented in this report are based on data from the 62 percent of California's autonomous, classroom-based and combination charter school facilities that completed all or part of a comprehensive survey. The sample of classroom-based charter schools is representative of the state in terms of school type, region, and management type. The policy recommendations presented in the Conclusions and Recommendations section of this report are based on: the charter school facility landscape in California, the national charter school facility landscape, and the collective expertise of the Resource Center, the Alliance, the League, and CCSA. California charter schools were asked to complete the Charter School Facilities Survey and allow a charter support organization representative to conduct an on-site measurement of the facility and educational spaces. Five key findings emerged from the study: (1) Meeting demand for California's charter schools will require new facilities solutions; (2) California's charter schools spend per-pupil revenue on facilities. The amount that charters spend on their facilities depends on the ownership situation; (3) California charter school facilities are not as large as the national public school median, and are generally smaller than recommended by California's public school size standards and guidelines; (4) California charter schools in district facilities face a number of challenges; and (5) California charter schools that share their facilities face a number of challenges.
