My wife was a teacher in a public school system, from time to time she would get a student that had been in a charter school. Generally, a charter school student needed help to catch up to the level of other students in her classroom. IMO charter schools are about protecting your child from “the good, the bad and the ugly” that occurs in public schools. Some of this is also fueled by the opportunity to make government supplied $$$$ and a nice profit. Lower wages for teaching staff and less enforcement of educational standards are a way to profit in charter school ownership.
