1. 1. Except as provided in section 334.260, all persons desiring to practice as physicians and surgeons in this state shall be examined as to their fitness to engage in such practice by the board. All persons applying for examination shall file a completed application with the board at least eighty days before the date set for examination upon blanks furnished by the board.

2. 2. The examination shall be sufficient to test the applicant's fitness to practice as a physician and surgeon. The examination shall be conducted in such a manner as to conceal the identity of the applicant until all examinations have been scored. In all such examinations an average score of not less than seventy-five percent is required to pass; provided, however, that the board may require applicants to take the Federation Licensing Examination, also known as FLEX, or the United States Medical Licensing Examination (USMLE). If the FLEX examination is required, a weighted average score of no less than seventy-five percent is required to pass. The passing score of the United States Medical Licensing Examination shall be determined by the board through rule and regulation. The board shall not issue a permanent license as a physician and surgeon or allow the Missouri state board examination to be administered to any applicant who has failed to achieve a passing score within three attempts on licensing examinations administered in one or more states or territories of the United States, the District of Columbia or Canada. The steps one, two and three of the United States Medical Licensing Examination shall be taken within a seven-year period with no more than three attempts on any step of the examination; however, the board may grant an extension of the seven-year period if the applicant has obtained a MD/PhD degree in a program accredited by the liaison committee on medical education (LCME) and a regional university accrediting body. The board may waive the provisions of this section if the applicant is licensed to practice as a physician and surgeon in another state of the United States, the District of Columbia or Canada and the applicant has achieved a passing score on a licensing examination administered in a state or territory of the United States or the District of Columbia and no license issued to the applicant has been disciplined in any state or territory of the United States or the District of Columbia. Prior to waiving the provisions of this section, the board may require the applicant to achieve a passing score on one of the following:

   1. (1) The American Specialty Board's certifying examination in the physician's field of specialization;
   2. (2) Part II of the FLEX; or
   3. (3) The Federation portion of the State Medical Board's Special Purpose Examination (SPEX).
3. 3. If the board waives the provisions of this section, then the license issued to the applicant may be limited or restricted to the applicant's board specialty. Scores from one test administration shall not be combined or averaged with scores from other test administrations to achieve a passing score. The board shall not be permitted to favor any particular school or system of healing.
