(1) Professional educator 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 educator advisory board consist of representatives who meet the qualifications of this subsection and who are from the role for which the professional educator advisory board has responsibility.

(2) If any professional educator advisory board receives a written request from other school districts or other public or private agencies for representation on such professional educator advisory board, the current members of such professional educator 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 educator advisory board without adding to the representation from the role for which the professional educator advisory board has responsibility if the professional educator advisory board authorizes such action by a majority vote.
