I found this site by accident but it is very interesting to say the least. I'm sure it has been mentioned here but I could find nothing using the search funcion. It lists every country and all schools accredited by that country. I can't say what the international credentials of each are but I'm sure folks on here could point in the right direction. www.4icu.org
For some added info, here is a link to wiki that lists all countries where English is considered the official language. I'm doing some research and will post any interesting finds. http://en.wikipedia.org/wiki/List_of_countries_where_English_is_an_official_language
My immediate concern is that the site has an "add school" listing and I am guessing that, unless the site operators really know their stuff, they would not catch fake accreditors and the like. Just a quick glance shows it has some questionable institutions, like the Windsor University School of Medicine in St. Kitts, which I don't think is GAAP accredited. From my position, you'd be a lot better off using CHEA.org in the US, and one of the directories published by GAAP-recognized agencies for international programs.
