The short version
In Florida, a microschool usually operates as a private school or serves families using the Personalized Education Program. Unlike some states, Florida asks private schools that want scholarship students to register with the state (FLDOE) and file an annual survey. Your work is your legal structure, that registration, your building, insurance, records, and connecting with the scholarship funding organization.
Why Florida is different
Florida's scholarships are huge, but the state expects more paperwork up front than Arizona or Texas — the FLDOE registration is a real gate. Get it right early and the large pool of scholarship families opens up.
