One Florida charter school has gotten into trouble for charging students for basic classes (not allowed in public schools, which charters technically are, even if in many ways they don't act like it). And its founder:
...set up the management company that runs the school on a $90,000 no-bid annual contract, and he owns the property on which Arts & Minds is located, meaning that the school pays rent to one of his companies. The Herald said that records show that the school pays more than $77,000 a month in rent, and the property on which the school is located is not taxed.
And he owns the company that provides school lunches—for a fee, of course.
It's not that every charter is like this. But they open up the possibility for these kind of abuses, especially as states rush to expand their charter systems without adequate oversight.
