The public schools, at least of NYC, absolutely stink. Perhaps originally they were doing good work, but the combination of the absolute filthy corruption of the Department of Education (what is in actuality a criminal entity made "kosher" by the facade of being a government sanctioned entity), the insane libtard no-fault student behavior now deemed acceptable by said criminal entity, and the lack of parental involvement resulting in disrespectful brats reporting to class and labeled as students has resulted in a seething, bubbling cesspool of pretend education. I recently saw a table of graduation rates vs. college readiness rates for 50 NYC high schools:
I guarantee you that there are good and bad teachers in all these schools. The difference is the school tone set by the students, what they bring with them from their home's tone and the level of parental involvement.
