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: 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.

Where to start in King County

Learn the mortgage arithmetic first

Homes in King County run about 6.6× median household income — well past the 3× rule of thumb. That makes amortisation, escrow, PMI and the true cost of a rate difference the most valuable arithmetic a resident can learn before signing anything.
