The Western Interstate Commission for Higher Education (WICHE) Professional Student Exchange Program enables students in 12 Western states to enroll in selected out-of-state professional programs, usually because those fields of study are not available at public institutions in their home states. Exchange students receive preference in admission. They pay reduced levels of tuition: for most students, resident tuition in public institutions or reduced standard tuition at private schools. The home state pays a support fee to the admitting school to help cover the cost of students' education. Fields supported include: (1) Dentistry; (2) Medicine; (3) Occupational Therapy; (4) Optometry; (5) Osteopathic Medicine; (6) Pharmacy; (7) Physical Therapy; (8) Physician Assistant; (9) Podiatry; and (10) Veterinary Medicine. State support and program participation affecting students are subject to change by legislative or administrative action. The number of students supported by each state is determined through state legislative appropriations. This publication identifies the available and participating Institutions, application information, individual state certifying offices, frequently asked questions, and potential alternative programs.
