This is a commuter click, as I suggest Liprap's tirade and additional research on for-profit management for schools for your perusal.
The telling quote (amongst many):
The charter's administrators will pass that blame on to teachers, who weren't teaching well enough to attract students that would stay, who couldn't establish a superhuman mentor/therapist/counseling/advocating role with each student along with their daily duties of imparting reading, writing, and arithmetic skills needed to pass every standardized test on the planet and show what a great school it desperately needed to be to survive.
We already hit on that the sustaining force behind many charter school movements is based on teachers whose lives become consumed with their work, or the thing doesn't work.
The first priority to ensure good, professional teachers get in and stay in your schools is to treat teaching like teaching is a profession, where you get to go to work during a certain time of day and go home during a certain time of day and enjoy your life, family, friends and hobbies.
If you need more, competent teachers, you shouldn't require them to be absolute superheroes to be successful. Because, if you do, your pool of applicants will be very, very small, and your turnover will be very, very high.
And, as a post-script, we should remember that one of the biggest "blame teachers" public officials in the United States is gearing up for another run at the Georgia Governor's mansion.
