The Western Interstate Commission for Higher Education (WICHE) annual survey of tuition and fees collects the resident and nonresident tuition and fees at public two- and four-year institutions in the WICHE region for undergraduate and graduate students. WICHE administered the most recent survey to state higher education executive offices, system offices, and institutions in each of the WICHE states, territories, and freely associated states in Summer 2023. Complete data from the survey are available on WICHE's online dashboard and enable comparisons of rates over time, across states, territories, and freely associated states, and between Carnegie Classifications. Unless otherwise indicated, tuition and fees rates are in current U.S. dollars, and average rates at the state and regional levels are weighted by full-time equivalent (FTE) enrollment. This WICHE Insights summarizes recent tuition and fees for undergraduates at public institutions in the West.
