S.D. Codified Laws § 13-32-4.6
If the superintendent of a school district determines that an expelled student has met the early reinstatement conditions established pursuant to § 13-32-4.5 that the student is required to meet before the student may be granted early reinstatement, the superintendent may grant the student early reinstatement and allow the student to return to school.
If a student violates an early reinstatement condition that the student was required to meet after the student's early reinstatement, but before the end of the expulsion period, the superintendent of the school district may revoke the student's early reinstatement. Within five days after revoking an early reinstatement, the superintendent shall provide written notice of the revocation including any early reinstatement condition that was violated by the student to the student's parent or guardian or to the student, if the student is at least eighteen years of age or an emancipated minor.
If a student's early reinstatement is revoked, the student's expulsion shall continue until the end of the original period of expulsion unless the student's expulsion is firearm-related and the original period of expulsion is modified by the superintendent pursuant to § 13-32-4.
