What South Dakota teaches — and to whom

South Dakota lets students satisfy the requirement with either Personal Finance or Economics. Which means for most residents of Castlewood, whatever they know about money they picked up somewhere other than a classroom.

LearnLife organises this the way the decisions actually arrive: Legal literacy — leases, contracts, employment rights and what a signature actually commits you to; Money — budgeting, credit, debt and taxes — the mechanics nobody is formally taught; Emotional regulation — the self-management that decides whether the other skills ever get used.
