Tuition and required fees at four-year institutions are reported by institution for four categories of students: resident undergraduate, nonresident undergraduate, resident graduate, and nonresident graduate. Tuition and required fees at two-year institutions are reported for resident in-district and nonresident students. Averages are reported for the region and for each of the 15 WICHE states. Also included are comparisons of tuition and fees by Carnegie Classification based on the 2005 Carnegie Classification of Higher Education Institutions. Tuition is defined as the total dollar amount charged to a full-time student for a full academic year, usually two semesters, three quarters, or two trimesters. Required fees include the institutional fees that a majority of full-time students are required to pay in addition to tuition.
