 To practice in Israel, doctors trained abroad must pass a licensing examination to ensure that their medical training is up to Israeli standards.Immigrant doctors who graduated from an American, British, Canadian, French, Australian, New Zealand, or South African medical school are exempt, provided they have 14 years of experience, including residency, and undergo a six-month internship-like "adjustment period" in Israel.As of 2011, there were 37,300 actively practicing nurses in Israel or 4.81 nurses per 1000 population compared to OECD country average of 8.7 nurses per 1000 population, ranking Israel one of the lowest nursing ratio countries in the developed world, after Greece, Mexico, and Turkey.
