(1) Professional education advisory boards may authorize the appointment of additional representatives from other school districts or other public and private agencies as long as one-half or more of the members of the professional education advisory board consist of representatives who meet the qualifications of this subsection and who are from the role for which the professional education advisory board has responsibility.

(2) If any professional education advisory board receives a written request from other school districts or other public or private agencies for representation on such professional education advisory board, the current members of such professional education advisory board shall vote on such request at the next regular meeting of such board. A program may elect to add private school representatives to a professional education advisory board without adding to the representation from the role for which the professional education advisory board has responsibility if the professional education advisory board authorizes such action by a majority vote.
