This annual report updates the tuition and fee prices published by all of the public higher education institutions in the Western Interstate Commission for Higher Education (WICHE) 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. Beginning with the 2010-2011 and continuing this year, this report presents published tuition and fees amounts as averages both unweighted and weighted by full-time equivalent (FTE) enrollments. Unlike unweighted 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 a typical student faces based on enrollment patterns. Appended are: (1) The Carnegie Classification of Institutions of Higher Education, 2010; (2) Number of Public Four-Year Institutions by Carnegie Classification in the WICHE Region, 2011-12; (3) Number of Public Two-Year Institutions by State in the WICHE Region, 2011-12; (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 21 tables and 68 endnotes.) [This paper was prepared by the Office of Policy Analysis and Research. For "Tuition & Fees in Public Higher Education in the West, 2010-2011.
