Here are a few from an old list I have
•WICHE: Western Interstate Commission for Higher Education operates a professional student exchange program (PSEP) enabling students in 15 western states to enroll in selected out of state professional programs,
•WWAMI: The University of Washington School of Medicine serves as the public medical school for Washington, Wyoming, Alaska, Montana, and Idaho. Students from these states will all be considered in- state students for purposes of admission and tuition.
•FAME: Finance Authority of Maine’s Maine Access to Medical Education Program has three medical schools (Dartmouth, Vermont & UNECOM) to provide PREFERRED ACCESS seats at each school for a total of twenty incoming, certified Maine residents each year. Essentially, this program removes Maine applicants from the national pool of applicants and allows them to compete for medical school acceptance in a pool consisting solely of Maine residents.
•DIMER: Delaware Institute of Medical Education and Research relationship with Jefferson Medical College of Thomas Jefferson University with at least 20 admissions places each year for Delaware residents. Philadelphia College of Osteopathic Medicine (PCOM), reserves at least 5 admissions places each year for Delaware residents.
