S.D. Codified Laws § 13-14-13
The governing board of any school district organized pursuant to chapter 13-5 may authorize one or more private, nonprofit benevolent organizations to, independently of the control of the school district, accept and solicit donations, gifts, grants, or other private financial resources for the ultimate benefit of the educational or interscholastic activities of the school district. Funds collected pursuant to this section and § 13-14-14 shall be offered, at an appropriate time, to the governing board of the school. If accepted, such funds shall be used for the expansion and enhancement of academic curricula, for the support of interscholastic activities, for the initiation or support of musical, forensic, civic, technologic, or similar extracurricular instruction or programs, for special trips or activities supporting core school activities, or other programs or activities of substantial benefit to the educational environment of the school district. None of the funds may be used for capital acquisition, debt retirement, or ordinary expenditures or expenses.
