Results released yesterday of test scores in the New York State Assessment Program showed that the most relentlessly attacked charter schools—Eva Moskowitz’s Harlem Success academies—have outperformed their public-school peers, often by a wide margin.

At all New York City’s public schools, 60% of third, fourth and fifth graders passed the math exam; at Harlem Success, 94% passed. In the state language arts exam, 49% from the city schools passed compared to 78% at the charters. The 94% pass rate for the academies’ black and Hispanic students surpassed the 73% pass rate for white students taking the exam in New York state.
