(1) Except as provided in subsection (2), an applicant, in addition to completing the requirements for the degree in medicine, shall complete a period of postgraduate education to attain proficiency in the practice of the profession, as prescribed by the board in rules, as a condition for more than limited licensure.

  (2) The board may grant a full license to practice medicine to an applicant who has completed the requirements for a degree in medicine at a medical school located outside the United States or Canada if, except as provided in subsection (4), the applicant demonstrates to the board all of the following:

  (a) That the applicant has engaged in the practice of medicine for not less than 10 years after completing the requirements for a degree in medicine.

  (b) That the applicant has completed not less than 3 years of postgraduate clinical training in an institution that has an affiliation with a medical school that is listed in a directory of medical schools published by the World Health Organization as approved by the board.

  (c) That the applicant has achieved a score determined by the board to be a passing score on an initial medical licensure examination approved by the board.

  (d) That the applicant has safely and competently practiced medicine under a clinical academic limited license granted by the board under this article for 1 or more academic institutions located in this state for not less than the 2 years immediately preceding the date of application for a license under this subsection, during which time the applicant functioned not less than 800 hours per year in the observation and treatment of patients.

  (3) An applicant who is required to meet the requirements of subsection (2)(d) shall file with the board a written statement from each academic institution upon which the applicant relies to satisfy that subsection. The statement shall indicate, at a minimum, that the applicant functioned for the academic institution in the observation and treatment of patients not less than 800 hours per year and that in so doing the applicant practiced medicine safely and competently. A person who in good faith makes a written statement that is filed under this subsection is not civilly or criminally liable for that statement. There is a rebuttable presumption that a person who makes a written statement that is filed under this subsection has done so in good faith.

  (4) Subsection (2)(c) and (d) do not apply to an applicant who was granted a clinical academic limited license after January 1, 2011 but before January 1, 2017 and who has continuously held a license to practice medicine from the effective date of the amendatory act that added this subsection through the date of application for a full license under subsection (2).
