(B) For FLEX examinations taken before June 1, 1985, the following standards apply:

An applicant for permanent licensure shall obtain, in one sitting, a FLEX weighted average score of at least seventy-five on the examination.

(C) For FLEX examinations taken after June 1, 1985, the following standards apply:

An applicant for permanent licensure shall obtain a score of seventy-five or more on both Component I and Component II. An applicant shall pass both components within five years of the first taking of any component of this examination.

(D) For the SPEX (Special Purpose) and COMVEX examinations, the following standards apply:

An applicant for permanent licensure who has not passed national boards, FLEX, SPEX, COMVEX, or been certified, recertified, or awarded a certificate of added qualifications by a specialty board recognized by the American Board of Medical Specialities or the American Osteopathic Association within ten years of the date of filing the application with this board shall pass the SPEX or COMVEX exam. A passing score on the SPEX examination is seventy-five or better. A passing score on the COMVEX examination must be established by the testing agency. This requirement is in addition to all other requirements for licensure. The SPEX or COMVEX examination requirement does not apply to a physician employed full time by the South Carolina Department of Corrections, South Carolina Department of Health and Environmental Control, State Department of Mental Health, and Department of Disabilities and Special Needs acting within the scope of his employment. A license issued to this physician is revoked immediately if he leaves the full-time employment or acts outside his scope of employment. However, the SPEX or COMVEX examination requirement applies to a physician providing services under a contract for the State and a physician providing services for which there is an expectation of payment, is payment for services, or should have been payment from a source other than the salary the physician receives from the State.
