Two state lawmakers are calling for an investigation into a large rally this week in support of charter schools, after it emerged that charter leaders canceled class and required students and staff to attend. Charter schools, which serve around 142,000 students in New York City, are privately managed but publicly funded. “Canceling classes during a school day and forcing families and students to engage in a political rally is an egregious misuse of instructional time and state funds,” the lawmakers wrote. The rally across the Brooklyn Bridge on Thursday featured thousands of charter parents, students and staff. “Nobody who works at Success should be surprised by this or should object to standing up for charter schools,” its spokesperson, Ann Powell, said in a statement on Wednesday.
