This issue of "Policy Insights" reviews the results from Western Interstate Commission for Higher Education's (WICHE's) annual survey of tuition and fees at public colleges and universities in the region. The survey on which the report and this policy brief are based was administered to state higher education executive offices or system offices in the Western states. The survey response rate was 100 percent. Respondents were invited to correct previous years' data, and the averages calculated were not weighted by enrollment. Average resident undergraduate tuition and fees for the academic year 2009-10 at public two-year institutions in the WICHE states increased by 6.4 percent ($160) from the previous year, while published prices at public four-year institutions grew by 12.5 percent ($639). By comparison, nationally, the one-year increase was 7.3 percent for two-year and 6.5 percent for four-year institutions. During the same period, the Consumer Price Index fell 2.1 percent. The increase in the regional average price for two-year institutions in the West was slightly below the national average increase. The increase in the regional average price for the West was substantially above the national average for four-year institutions (by 22.3 percent), though the actual average tuition within the region for these institutions remains substantially below the national average.
