In spring of 2012, the Idaho Charter School Network, the Colorado League of Charter Schools, and the National Alliance for Public Charter Schools worked to collect evidence that would accurately portray both the adequacy of charter school facilities and the average spending for facilities out of charter schools' operating budgets in Idaho. Collectively, the results described in this report provide evidence that charter school students in Idaho do not have access to the same facilities and amenities compared to traditional public school students. In order to ensure that the recommendations of this effort were research-based and supported by reliable data, Hutton Architecture Studio consulted on the project to provide a set of reasonable expectations for school facilities' size and amenities. The Facilities Initiative caught the attention of the U.S. Department of Education who is currently funding four state reports, including Idaho. The National Charter School Resource Center at American Institutes for Research (AIR) is subcontracting with the Colorado League of Charter Schools to collect the research and data on behalf of the U.S. Department of Education for Idaho, Massachusetts (ED561929), Michigan (ED561921), and New Jersey (ED561926). This report is based on survey, enrollment, and operating revenue data collected for the 2010-2011 school year. Results are based on data from the 96 percent of Idaho's charter schools that completed all or part of a comprehensive facility survey. Participating schools were representative of the state's charter sector as far as size of enrollment, percentage of minorities and low income students served, grade levels served and per-pupil operating revenue. Appended are: (1) Methodology; and (2) School Facility Standards.
