The Western Undergraduate Exchange (WUE)--the nation's largest regional tuition-reciprocity program--is celebrating its 30th year of regional exchange in the 2017-18 academic year. The tuition reciprocity agreement allows nonresident students from a WICHE state to enroll in participating two- or four-year public institutions located in another WICHE state, and pay no more than 150 percent of the enrolling institution's resident tuition--a significant savings over regular nonresident tuition. Students can choose from some 160 participating institutions and a wide range of majors. In 2017-18, more than 40,090 WUE students and their families saved over $365.4 million in tuition. Student savings can run as high as $21,700 per academic year, but the average WUE university student this year saved almost $9,000 and the average community college student saved more than $4,600. Since 1988, WUE has provided Western students and families discounts on almost 541,850 annual tuition bills--saving them, overall, $3.6 billion over the last 30 years. The tremendous savings WUE offers Western students is clear, but it doesn't stop there. Students can gain affordable access to majors not offered in their home state. And sometimes, depending on tuition and living costs in the student's home state, it may cost less to study out-of-state with WUE. Most WUE institutions make all or most majors available at the WUE rate, but they can exclude majors in high demand. Transfer students can qualify for the WUE rate at most institutions. Some institutions establish higher academic requirements for applicants to qualify for the discounted tuition rate, but most award the WUE rate to all nonresidents from another WICHE state. Western states also benefit greatly from the WUE participation of their public institutions. WUE is an ideal "relief valve" for states that lack sufficient capacity in their public higher education system at any given time. And, institutions tout how WUE helps them meet recruitment and enrollment goals. WUE institutions determine the number of discounted seats they will offer, any special admissions requirements for the WUE rate, and which majors are eligible. Students apply directly to the institutions they're interested in.
