What Illinois teaches — and to whom
Illinois 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: 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; Emotional regulation — the self-management that decides whether the other skills ever get used.

Start with the money that moves every month
For most households in Grayslake, the fastest gain is not an investing strategy — it is seeing the recurring outflows clearly, knowing what a credit score actually responds to, and understanding which line items on a payslip are negotiable.
