Wis. Admin. Code Med § 1.08
If an applicant has been examined 4 or more times in another licensing jurisdiction in the United States or Canada before achieving a passing grade in written or computer-based examinations also required under this chapter, the board may require the applicant to submit evidence satisfactory to the board of further professional training or education in examination areas in which the applicant had previously demonstrated deficiencies. If the evidence provided by the applicant is not satisfactory to the board, the board may require the applicant to obtain further professional training or education as the board deems necessary to establish the applicant's fitness to practice medicine and surgery in this state. In order to determine any further professional training or education requirement, the board shall consider any information available relating to the quality of the applicant's previous practice, including the results of the applicant's performance on the oral examination required under s. 448.05(6), Stats., and s. Med 1.06.
