"The NYS Board of Regents has decided to permit the Ember Charter School in B'klyn to expand& add a high school. How they get permission to expand is definitely a scandal. Charter schools get permission to grow if they have demonstrated success. Gary Rubinstein checked state data and found that Ember’s greatest “success” was getting rid of students by attrition. The Regents must know this too. Why did they vote to expand a failing charter school? Charter school supporters often complain that the cap needs to be lifted. But there are two ways that charters can get more students even without lifting the cap. The most obvious way is for charters to reduce their attrition rates.So just like so many other charter schools, when they can’t cheat by booting out their students, their test scores are nothing special.
