From the Florida Department of Education:
“Certification of private school teachers and administrators is not required in Florida.”
Private elementary and secondary schools are not licensed, approved, accredited or regulated by the Department of Education.
Florida’s private schools issue independent school diplomas that do not require approval from the state of Florida.
Florida private schools establish their own system of school accountability, grading, reporting, and evaluating and are not included in the state’s measurement of public schools.
Private elementary and secondary schools are structured as private corporations, churches or private businesses that only report directory information and the enrollment of compulsory attendance aged students to the Department of Education.
Private schools are not subject to school definitions and requirements specified in education statutes and they are not under the jurisdiction of the Department of Education.
So, if you want unregulated schools where the janitor can teach, Florida says OK!
