The CEO of UNO/Acero Charter Schools, Robert Rodriguez, is angry that his teachers went out on strike. He blames the union and “outside” interests who are anti-charter. Apparently, he does not take seriously his teachers’ demands for higher pay and smaller class sizes. He disrespects them by not hearing their voices.

He released this letter.

This is a video of him reading his letter.

In his letter and statement, he describes Acero as “one of the best performing charter networks in Chicago.”

Dana Goldstein wrote in the New York Times, however, that “At Acero schools, a quarter of students met standards on state exams in 2016, the same percentage who met standards in the Chicago district schools, according to a report from the Illinois State Board of Education.”

If that is what it means to be “one of the best performing charter networks in Chicago,” that speaks poorly of the entire charter sector.
