A summary is presented of data available on graduate tuition and fees, numbers of graduate programs and degrees conferred, and residence and mobility of graduate and first-professional students in the 13 states that comprise the Western Interstate Commission for Higher Education. Graduate tuition levels in the 13 western states vary widely for both resident and nonresident students. The median resident tuition was $545 compared to a median nonresident tuition of $l,632. Despite these tuition barriers, large numbers of students do migrate to attend graduate and first-professional school. Only three states experienced a net out-migration of graduate students in Fall 1975. Only four states attracted more first-professional students than the number of their state residents attending first-professional schools in other states. The migration of graduate and first-professional students has not been the subject of policy research and evaluation from a regional perspective, nor has the impact of tuition rates been viewed from a regional planning perspective. Appendices provide 1977-78 graduate tuition and fees at public institutions in the west; Ph.D. programs available in six western states, number of doctoral degrees awarded, and average number of degrees awarded per program in 1975-76; and graduate enrollment at state universities and land grant colleges during the Fall of 1976 and 1977.
