What Washington teaches — and to whom
Washington requires personal finance instruction, but folds it into another course rather than a class of its own — so how much a student actually gets depends heavily on the district and the teacher. Coverage like that varies enormously between districts, and it reaches no one who has already graduated.
LearnLife organises this the way the decisions actually arrive: Emotional regulation — the self-management that decides whether the other skills ever get used; Money — budgeting, credit, debt and taxes — the mechanics nobody is formally taught; Legal literacy — leases, contracts, employment rights and what a signature actually commits you to.
