S.D. Codified Laws § 13-32-14

If a school district does not have a bullying policy, the school district shall follow the model bullying policy in § 13-32-19 until such time as the school district adopts its own bullying policy. Nothing in §§ 13-32-14 to 13-32-19, inclusive, supplants or preempts an existing school district policy, except that no school district policy prohibiting bullying, whether it is existing or adopted pursuant to §§ 13-32-14 to 13-32-19, inclusive, may contain any protected classes of students.
