1. FAFSA — federal need-based aid
The Free Application for Federal Student Aid. Opens Oct 1 each senior year. Most state and school aid uses your kid's FAFSA score, so even if you don't expect federal aid, you have to file to unlock everything else. It's not optional — it's the unlock for the whole financial aid universe.
Your role: You provide the income data. The kid fills the rest. File ASAP after Oct 1 — most aid is first-come, first-served.
