This report provides comprehensive data about the tuition and fee prices published by the public higher education institutions in the Western Interstate Commission for Higher Education (WICHE) region for 2017-18, including changes over the past one-, five- and 10-year periods. For the first time, this annual series also displays the one-, five-, and 10-year trends of mandatory student fees separate from total tuition and fees. 08 to 2017-18, tuition and fees at public two-year institutions (without California) and four-year institutions increased 31.2 percent and 54.3 percent, respectively when adjusted for inflation (Figures 1 and 2). The largest cumulative change in tuition and fees occurred between 2007-08 and 2011-12, when year-over-year increases were considerably higher than the rates of increase between 2012-13 and 2017-18. This year's annual increases are more substantial than the more recent five-year's rates of increase for the WICHE region and may suggest a resumption of the previous trend.
