S.D. Codified Laws § 34-45-24

No person may be appointed as a 911 telecommunicator, except on a temporary or probationary basis, unless the person has satisfactorily completed a preparatory program of 911 telecommunicator training at a school approved by the commission. No 911 telecommunicator may be employed on a temporary or probationary basis beyond one year if the telecommunicator lacks the educational and training qualifications required by the commission. However, in municipalities of the third class, a 911 telecommunicator's probationary period may be extended for one additional year.
