Diane Ravitch says: "I like this post by Peter Greene a lot because it clears up confusion about what defines a public school. Many people think that charter schools are public schools because most state laws define them as “public charter schools.” The charter industry wrote the state laws, and they desperately wanted to be considered “public schools” so they could qualify for the same funding as public schools (in Texas, they get even more funding than real public schools). The proliferation of corporate charter chains make it even harder to see charter schools as public schools, since nowhere in the history of public schools were multiple schools managed by a corporation. Read, because If your school doesn’t meet these minimal requirements, it is not a public school. "
