(1)    Grant of license or certificate. Subject to s. 448.05 (1) (d), if three-fourths of the members of the board find that an applicant who has passed the required examinations is qualified, the board shall so notify the applicant and shall grant the license or certificate.

   (1m)   Grant of limited license or certificate. If the board finds, based upon considerations of public health and safety, that the applicant has not demonstrated adequate education, training or performance on examinations or in past practice, if any, to qualify for full licensure or certification under sub. (1), the board may grant the applicant a limited license or certificate and shall so notify the applicant.

   (2)   Denial of license or certificate. The board may deny an application for any class of license or certificate and refuse to grant such license or certificate on the basis of unprofessional conduct on the part of the applicant, failure to possess the education and training required for that class of license or certificate for which application is made, or failure to achieve a passing grade in the required examinations.
