This website, called “KnowYourCharter” is powerful. It dispels the myth that charter schools are superior to public schools. A few are, but most are not. Even in some of the lowest-performing, most impoverished districts in the state, the public schools outperform many charter schools.
You can plug in the name of any school district in the state and see how the public school district compares to individual charter schools. They are compared by such factors as state funding per pupil, overall state performance rating, average teaching experience of teachers, and how much money the charters extract from the public system.
It takes only a moment to click the button. Open the link and you will learn more in a few minutes than by reading tomes about charters.
