What California teaches — and to whom
California has committed to 1 semester of personal finance as a graduation requirement, phasing in with the class of 2031 — so today's middle schoolers will be the first cohort held to it. That covers students still in the system. It does nothing for the adults already out of it — which, in San Marcos, is most of the people reading this.
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.
