S.D. Codified Laws § 13-32-9
Any person adjudicated, convicted, the subject of an informal adjustment or court-approved diversion program, or the subject of a suspended imposition of sentence or suspended adjudication of delinquency for possession, use, or distribution of controlled drugs or substances or marijuana as defined in chapter 22-42, or for ingesting, inhaling, or otherwise taking into the body any substances as prohibited by § 22-42-15, is ineligible to participate in any extracurricular activity at any secondary school accredited by the Department of Education for one calendar year from the date of adjudication, conviction, diversion, or suspended imposition of sentence. The one-year suspension may be reduced to thirty calendar days if the person participates in an assessment with a certified or licensed addiction counselor. If the assessment indicates the need for a higher level of care, the student is required to complete the prescribed program before becoming eligible to participate in extracurricular activities. Upon a second adjudication, conviction, diversion, or suspended imposition of a sentence for possession, use, or distribution of controlled drugs, substances, or marijuana as defined in chapter 22-42, or for ingesting, inhaling, or otherwise taking into the body any substance as prohibited by § 22-42-15, by a court of competent jurisdiction, that person is ineligible to participate in any extracurricular activity at any secondary school accredited by the Department of Education for one year from the date of adjudication, conviction, diversion, or suspended imposition of sentence. The one year suspension may be reduced to sixty calendar days if the person completes an accredited intensive prevention or treatment program. Upon a third or subsequent adjudication, conviction, diversion, or suspended imposition of sentence for possession, use, or distribution of controlled drugs or substances or marijuana as defined in chapter 22-42, or for ingesting, inhaling, or otherwise taking into the body any substances as prohibited by § 22-42-15, by a court of competent jurisdiction, that person is ineligible to participate in any extracurricular activity at any secondary school accredited by the Department of Education. Upon such a determination in any juvenile court proceeding the Unified Judicial System shall give notice of that determination to the South Dakota High School Activities Association and the chief administrator of the school in which the person is participating in any extracurricular activity. The Unified Judicial System shall give notice to the chief administrators of secondary schools accredited by the Department of Education for any such determination in a court proceeding for any person eighteen to twenty-one years of age without regard to current status in school or involvement in extracurricular activities. The notice shall include name, date of birth, city of residence, and offense. The chief administrator shall give notice to the South Dakota High School Activities Association if any such person is participating in extracurricular activities.
Upon placement of the person in an informal adjustment or court-approved diversion program, the state's attorney who placed the person in that program shall give notice of that placement to the South Dakota High School Activities Association and chief administrator of the school in which the person is participating in any extracurricular activity.
As used in this section, the term, extracurricular activity, means any activity sanctioned by the South Dakota High School Activities Association. Students are ineligible to participate in activity events, competitions, and performances, but a local school district may allow a student to participate in practices.
