What Arizona teaches — and to whom
Arizona 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.

A median age of 26.7 means a large share of St. Johns is making decisions with thirty-year consequences: the first credit card, the first lease, whether to take the employer match. These are cheap to get right now and expensive to unwind later.
