S.D. Codified Laws § 36-4-19

However, the board may require the applicant to successfully pass either an oral or written examination and personally appear before the board, a member of the board, or its staff.
Each applicant applying under the provisions of this chapter shall pay to the secretary of the board a license fee not to exceed four hundred dollars to be set by the board by rule promulgated pursuant to chapter 1-26.
