<p>Other nations do use the MD degree, but many use it as an advanced medical degree, usually research oriented (sort of like a PhD), while the standard professional degree is MBBS. Depends on the country though - there are a lot of different ways this is handled.</p>
<p>The caribbean schools do grant the MD degree. They teach to the american model and prepare specifically for the USMLE tests (some better than others) because they exist only to train US and Canadian citizens (granted, there are UK and Irish and others at these schools, but their primary purpose is to train US students who didn’t get into US schools).</p>
<p>The pass rate for students from non-US and non-canadian schools is actually around 73% (cite: [USMLE®</a> : Scores & Transcripts](<a href=“http://www.usmle.org/Scores_Transcripts/performance/2009.html]USMLE®”>http://www.usmle.org/Scores_Transcripts/performance/2009.html)) - this takes into account both US citizen caribbean students and non-citizen foreign grads, however.
Compare that to a pass rate of 95% for US MD schools.</p>
