S.D. Codified Laws § 36-18A-14
The Board of Technical Professions is created to administer the provisions of this chapter. Each member of the board shall receive a certificate of appointment from the Governor and shall file with the secretary of state a written oath for the faithful discharge of the member's official duties. The board shall consist of seven members to be appointed by the Governor for a term of three years. No member may serve more than three consecutive full terms. However, appointment to fill an unexpired term is not considered a complete term for this purpose. The board shall be composed of two professional engineers, two architects, two land surveyors, and one member from the public. The Governor may stagger the terms to enable the board to have different terms expire each year. Any member appointed to the board prior to July 1, 2005, shall serve the four-year term to which the member was originally appointed. Any member appointed to the board after July 1, 2005, shall serve a three-year term.
