This annual report updates the tuition and fee prices published by all of the public higher education institutions in the WICHE (Western Interstate Commission for Higher Education) member states. It is the product of an annual survey administered to the State Higher Education Executive Officers (SHEEO) offices in each state, with a couple of exceptions. There is no centralized coordinating or governing body for the two-year colleges in Arizona or for the technical institutes in South Dakota. Therefore, personnel at the individual institutions in those two states responded to this survey. In response to feedback from WICHE constituents, this year's edition incorporates three significant changes: 1) the addition of enrollment-weighted tuition and fee averages by state; 2) the ability to download all data tables in excel format, most notably the tables that show each institutions' tuition and fees charges; and 3) a reduction in the total number of data tables to eliminate redundancy and streamline the report. Unlike unweighted tuition and fee averages, which treat each institution equally no matter how big or small it is, enrollment-weighted averages provide a truer estimate of the published price an average student faces based on enrollment patterns. Appended are: (1) The Carnegie Classification of Institutions of Higher Education, 2005; (2) Number of Public Four-Year Institutions by Carnegie Classification in the WICHE Region, 2010-11; (3) Number of Public Two-Year Institutions by State in the WICHE Region, 2010-11; (4) Procedure for Converting Current Dollars To Constant Dollars; (5) Methodology; (6) Survey Instructions; (7) Mandatory Fees at Public Two-Year Institutions in the WICHE Region; (8) Mandatory Fees at Public Four-Year Institutions in the WICHE Region; (9) Undergraduate FTE Four-Year Institutions in the WICHE Region; (10) Graduate FTE Four-Year Institutions in the WICHE Region; and (11) Undergraduate FTE Two-Year Institutions in the WICHE Region. (Contains 20 tables and 73 endnotes.) [This paper was prepared by the Office of Policy Analysis and Research. For "Tuition and Fees in Public Higher Education in the West, 2009-2010.
