In 1991, the university introduced programs in English, starting in 1993 with the four-year M.D. program based entirely on the American curriculum and the requirements of the United States Medical Licensing Examination (USMLE) system. A six-year M.D. program in English based on the European model followed a year later. Both programs have instituted National Board of Medical Examiners (NBME) subject examinations and compulsory completion on USMLE licensing examinations as a requirement for students. Subsequently, PUMS reached the last of its planned English-language based projects with the introduction of a five-year Dentistry program in 2000, and five-year M.Sc. Pharmacy program in 2004, which was replaced by the six-year Pharm. D. program in 2009, and three-year B.Sc. Physiotherapy program in 2009. These programs meet the European requirements. The students of the english programs are represented by the English Programs' Student Union (EPSU).
