S.D. Codified Laws § 13-13-72.1
Any adjustments in the levies specified in § 10-12-42 made pursuant to §§ 13-13-71 and 13-13-72 shall be based on maintaining the relationship between statewide local effort as a percentage of statewide local need in the fiscal year succeeding the fiscal year in which the adjustment is made. For school fiscal years 2017 to 2022, inclusive, the proportion of local need paid by local effort and state aid shall be adjusted annually to reflect adjustments in local effort due to the implementation of the other revenue base amount as defined in § 13-13-10.1. However, if the levies specified in § 10-12-42 are not adjusted to maintain this relationship, the target teacher salary as defined in § 13-13-10.1 shall be reduced to maintain the relationship between statewide local effort as a percentage of statewide local need.
