I found very interesting article "Medical education in the Caribbean: a longitudinal study of United States medical licensing examination performance, 2000-2009."
SMU's STEP 1 pass rate is not exactly what administration states on the website "With US Medical Licensing Examination Step One pass rates of above 90%, our students' performance is on parity with students from U.S. medical schools and far above the average level of students from other non-U.S. schools (61%)." The website was updated last time 05/01/09"
The article says that first attempt pass rate of SMU students was 59,6% in 2008 and dropped to 51,6% in 2009.
Basically SMU's pass rate is lower then that of Jamaican students..
BTW STEP 2 CK is not that great either 65,3% in 2009 vs. 81,3% of Cuban students (Spanish speaking!!!)
