In Turkey, the medical degree/diploma of the physician candidate, when approved by the Ministry of Health, also acts as a licence to practice medicine. There is no separate licensing process for physicians (and for other healthcare professionals). The approval process of the degree does not rely on any well-established criteria (it is simply and seal and sign process) and there is no real system that evaluates the competency of healthcare professionals. Needless to say that, there is no such thing as re-licencing...
I find this situation to be very problematic for a number of reasons that I will not go into detail here, but I would be thankful if you could offer some insight regarding the way licencing procedures are handled in your country. You do not need to offer detailed information; you can simply recommend relevant publications and other sources (such as websites) to point me in the right direction.
